Glen MacDonald to head White Mountain Research Center

By Karen A. Lefkowitz

Moving to the front lines of climate change, UCLA professor Glen MacDonald recently accepted a position as director of the White Mountain Research Center. The multi-station center is situated among diverse ecosystems ranging from high alpine to arid deserts east of the Sierra Nevada, 270 miles north of Los Angeles.

“This is an amazing setting to explore and contemplate the interplay between human cultures and nature, the environment and art, and environmental communications,” MacDonald said.

In operation since 1948, the center supports research, field classes, workshops and conferences for a range of disciplines, from astronomy to ecology. Management of the center was transferred to UCLA from the University of California, San Diego in 2012. MacDonald takes over for Tony Orme, a geography professor who oversaw the transition. The center has been modernized and refurbished and now includes two high-elevation stations running on off-grid solar power. But not everything is new—the center’s Crooked Creek Station is close to a 5,065 year-old bristlecone pine that’s believed to be the oldest living tree in the world.

MacDonald is a member of the National Academy of Sciences, former director of the Institute for the Environment and Sustainability, and the John Muir Memorial Chair of Geography. His research focuses on climate change, water resources in arid locations and biogeography. MacDonald said he looks forward to educating the next generation of environmental scientists and expanding the facility’s ability to track the impacts of climate change.

In Memoriam Hal Klieforth

Hal Klieforth

We mourn the passing of meteorologist Hal Klieforth, a longtime friend of WMRS/WMRC. After graduating from UCLA Hal came to Bishop for the Sierra Wave project in 1951. When not soaring high above Owens Valley on record-setting glider flights, he befriended WMRS staff who had just constructed Barcroft Station. Hal thus had the distinction of having been one of the earliest visitors to Barcroft, having dined there just before its temporary abandonment during the winter of 1951-52.

He maintained his interest in WMRS throughout his life, and was honored at the 2008 WMRS CEREC Conference, along with his friend Derham Giuliani, for contributions to science and natural history of the Eastern Sierra. His knowledge, energy, and unfailing courtesy will be missed.

Crooked Creek Station is going off grid!

WMRC staff recently installed 12 solar panels on the roof of Crooked Creek Station along with the necessary inverters to convert the solar energy. More panels will be installed early next spring allowing Crooked Creek Station to operate off grid.

This field station is located in the Ancient Bristlecone Pine Forest at an elevation of 10,200’ in the White Mountains. It is an ideal facility in which to teach field classes, conduct research, and to hold workshops and retreats. Crooked Creek Station offers meals and accomodations for up to 45 people. There is high speed internet access, four dry lab spaces and a classroom. The station is open from about June 1 to about October 31.

The Effects of Warming and Shading on Alpine Cushion Plants in the White Mountains.
Chris Kopp, phD student, UC San Diego.

This past summer (2011) was my second field season at WMRC. In 2010, I arrived in the White Mountains as a newly minted Ph.D. student at UC San Diego who was enthusiastic about working in the mountains, but in need of a focused dissertation project. The best way for me to become familiar with the Whites, and its diverse plant communities, was to get out and explore the landscape. This exploration took the form of a resurvey of work done by Harold Mooney back in 1961. In Dr. Mooney’s original survey, he and his associates described the distribution and abundance of several plant species that were recorded along line transects between 2,900 m (9,500 ft) and 3,950 m (13,000 ft) of elevation. In the summer of 2010, I set out to replicate this survey to find out if there had been shifts in species distributions and abundances in the past 49-years. I found that sagebrush (Artemisia arbuscula) advanced its upper elevational range margin on granitic soils as much as 150 m (500 ft) from the original 1961 survey. This upward range expansion coincided with significant declines in abundance of three alpine cushion plants: Anderson’s Clover (Trifolium andersonii), condensed phlox(Phlox condensata), andoval-leaved buckwheat(Eriogonum ovalifolium). There were, however, smaller, but significant, declines in these species at higher elevations and on soil types wheresagebrushhad already become abundant in 1961. These changes occurred during a period of increasing temperatures in the White Mountains.Together, these results suggest that rising temperatures may be negatively impacting these alpine plant communities via both direct and indirect mechanisms, increasing the likelihood these communities will be lost. Based on these results I have established an experiment that tests the effects of warming and shading by sagebrush on alpine plant cushion plants in the White Mountains.

During the 2011 field season, I established these experiments at two sites near Crooked Creek and Barcroft. At each site I constructed passive warming chambers and shading structures. The warming chamber will examine the response of the species described earlier to temperatures increased 1-3 °C above ambient. The shading experiment employs shade cloth mounted over cushion plants to test their response to simulated shading by sagebrush. My expectation is that warming will enhance fitness (growth, flower and seed production, etc.) of sagebrush but decrease fitness of cushion plants. I expect shading will decrease fitness of cushion plants indicating their inability to withstand encroachment by sagebrush. These experiments will continue through the 2013 field season and I am excited to see what results are yielded.

My first two years in the White Mountains have been a great success thanks to the tremendous help, hospitality and cooking of the WMRC staff. I am looking forward to continuing my research here and interacting with all the great friends and scientists I have met thus far!


The 2011 Open House at Barcroft on Sunday August 7th was a tremendous success. Beautiful weather and an outstanding crew of volunteers (thank you Friends of WMRC!!) provided a unique and enjoyable summer outing for over 450 guests! Talks, video presentations, building tours and tours of the energy system were available all day, and over 120 dozen homemade cookies were provided by our cooks. Thanks to our scheduling coordinator Denise Waterbury for organizing all this, and special thanks to Olin Beall and the USFS engineers who graded the washed out White Mountain Road just in time for the event. See photos!

Barcroft Field Station opens July 7. The warm weather permitted WMRC staff to open the road to Barcroft, and we plan to open the station later this week. Currently we recommend 4wd only because of muddy spots in the road.

The Physiological Ecology meetings were cancelled this year. These are normally held every June at the WMRC Owens Valley Laboratory.

September 2010 Bighorn Sheep Exclusion Fence In recent years the Barcroft Domestic Sheep Facility has been undergoing major renovation in order to eliinate any possible contact between the domestic sheep and the wild Desert Bighorn sheep that roam the Whites. Along with WMRC assistance and under the direction Ben Gonzales, Department of Fish and Game, staff from the Loma Linda University Animal Care facility completed the final stage of these improvements. A 10' high gated pen now surrounds the domestic sheep dung trailer. The fence also surrounds the rest of the sheep facility (see photo-click on photo to enlarge).With this final improvement, dung collected from the sheep pens is directly deposited inside the trailer. Runoff control barriers prevent dung or dung-laden water from escaping the fenced area. When full, the trailer is covered with a tight-fitting canvas tarp and driven down to Bishop for disposal.

This sheep facility supports one of WMRC' flagship projects, a long-term, multi-million dollar effort to understand how low oxygen harms pregnancy and fetal development. In 2009 this project was rated as one of the nation's top health science projects by the National Institutes of Health (NIH).

Barcroft update, September 1, 2010: WMRC staff re-install 68 solar panels on the roof of the Pace lab. After a major effort including about 25 person days of work, all the solar panels but one were re-installed by gluing them directly to the roof surface using many gallons of EPDM adhesive. As of today all 68 of the panels are connected to the battery bank and are generating 6 KW of electricity at mid-day. The solar-battery installation is so effective that it is seldom necessary to run the backup generator, saving thousands of gallons of fossil fuel every summer. see WMEP web site for more information see also carbon offsets page.

New opportunity for UC GRADUATE STUDENTS working at WMRC! The Mildred E. Mathias Graduate Student Research Grant Program is now open to all Graduate Students currently enrolled at any of the University of California campuses. There are no restrictions on the research topic, and students from all academic disciplines are strongly encouraged to apply. The maximum individual grant is $3,000, and the limit on total awards is $38,000.  The deadline for submitting an application is 8:00 am on October 18, 2010.  Letters of recommendation and permissions to use reserve(s), are due no later than 8:00 am on October 27, 2010. See Matthias grant flyer for details. Please note that the WMRC minigrant program (open to all graduate students from all institutions) will probably also be announced in November or December.

July 28-30, 2010 WMRC hosts Review Committee from the UCNRS. In June 2010, WMRC submitted an application to join the UC Natural Reserve System. In July a Review Committee, chaired by UCLA Professor Tony Orme, made a site visit to the station. They were favorably impressed with the scope and breadth of station activities, and are preparing a report which should move the process along. Although there are questions which need to be answered and details to be worked out, joining the UCNRS would bring more resources and expertise to WMRC. It would also give us a new administrative home within the Office of Research.

Annual Open House at Barcroft, Sunday August 1, 2010 between 6:30 am to 6 pm. Beautiful weather brings a large crowd for an inside look at one of North America's most unique scientific facilities. . Highlights included the Road Kill Museum, lectures by faculty, staff and graduate students, tours of the energy and astrophysics labs, souvenir sales, unlimited free cookies baked by WMRC cooks and, of course, the unparalleled high altitude scenery at 12,500 feet elevation.

July 2, 2010: WMRC staff re-install 33 solar panels and revive battery-inverter system: hope for a full recovery. Once the road opened WMRC staff began a top-priority scramble to recover the solar electrical system (see below for details). The fallen solar panels were straightenend and cleaned, and tested for generating capacity. Remarkably, the 60 panels retained 60-100% of their power (mostly 100%), enough to justify their re-installation. The new mounting system glues the panels directly to the roof. The dead batteries were also revived by a multi-step process which has resulted in at least a partial recovery. On June 30, the generator was shut off after running continuously for 6 days, and the station returned to partial solar/battery power. We plan to remount the remaining solar panels next week and to complete the re-installation over the next few weeks. We are hoping for a full system recovery but this can only be determined by actual performance.

Trek to Barcroft, May 28, 2010: Winter storm sweeps away Barcoft solar panels. The heavy snows and delayed spring snowmelt in 2010 prevented WMRC staff from reaching Barcroft in winter/spring 2010. We knew via remote monitoring that the main power sytem had shut down, but we didn't know why. Getting up to Crooked Creek has been delayed by large snow drifts, and once the way was open the snow was too soft for easy passage. Finally, on May 28, WMRC Associate Director John Smiley was able to drive the snow cat to the base of Sheep Pass; close enough to enable a 6-mile hike up to the station. See full story for what he found, with details and photos.

On March 31, the Owens Valley Roadside Heritage Project hosted an Open House celebrating completion of their new CD "Exploring Extreme Environments: Audio Stories from California's Eastern Sierra." The Eastern Sierra Watershed Project also displayed results of their environmental education program centered on the lower Owens River. These projects have been sponsored by the Eastern Sierra Institute for Collaborative Education in partnership with WMRC, the National Science Foundation, and other organizations.

Major Budget Cuts at the University of California are forcing reductions in the level of service WMRC offers researchers and classes. We have cut staff hours from their already minimal levels, and the entire staff is currently taking unpaid furloughs. The most visible effect will be felt at Crooked Creek. There, in 2010, we plan to offer meal service only to groups larger than 10 persons. Individuals, couples and smaller groups will have to purchase, transport and cook their own meals while at Crooked Creek, except when they overlap with a larger group for which meals are being prepared. It is very important that visitors plan their trips to Crooked Creek (and the other stations) well in advance (at least 2 weeks and preferably a month or more). We ask our station users to be patient through these difficult times, and please know that our primary concern is to support you, the station users, in safety and as much comfort as our field conditions allow.

October 2009 In cooperation with the USGS Western Ecological Research Center (WERC), WMRC has recently completed an 1800 square foot, climate-controlled greenhouse at the Owens Valley Laboratories.  The greenhouse will initially be used to germinate soil samples (looking at seed banks in desert plant communities), but may be used for other compatible research as space becomes available.  The construction of the greenhouse is part of WERC's recent expansion of their Yosemite Field Station to include an office in Bishop, as well as their two offices in Yosemite.  In addition to the plant restoration work involving the greenhouse, WERC has also received funding to conduct assessments of wildlife in the high altitude Sierra Nevada and White Mountain ranges.  This involves monitoring transects across the Sierra Crest in several locations, counting Bighorn Sheep, Pika, Marmots, Belding and Golden-mantled Ground Squirrels, and then modeling the effects of climate change to predict future range shifts for these species. WERC researchers are collaborating with students and faculty from UC Merced, UC Davis and Cal Poly San Lius Obispo on these and other projects in our region.

July 2009. Major lighting storm damages some equipment at Barcroft, but main power system OK. Barcroft Report from Dori Cann:

7/23/09 Around 7 pm a squall was happening over Piute mtn.I was out in the sheep pens feeding them their evening meal.Looking over at Piute I could see alot of hail and graupel was covering the ground.A few lightnings were striking over there.I finished up with the sheep quickly and ran back over to main building to tell everyone(there were 9 of us here) to check out the good lightning show.So we all stood in the office oohing and ahhing.After 15 mins or so it was obvious that the storm was moving our way.Lightnings quickly fallowed by thunder.Amazing strikes with parts branching off left and right.So bright we would be blinded for a moment .Then a close one with sparks coming out of the outlets.And a few minutes a lightning that seemed to hit the back(west end )of the building and a loud crack and the power was out.Wow,as we are generating our own power that might mean we were struck!We let some more time go by and then went out to look (not touch ) the mian electric panel to see if there was any obvious sign of why power was out.I was walking back in front of shop bench to get flashlight and another crack and bright blue sparks flew out of the outlets on work bench.And that happened with power out.by now it was 8 pm and things were settling down.Went to check what I could and was able to fire up diesel generator and get power to building. Decided to look for any damage in the morning.

7-29-09 Lightning visited the area in a big way last Thursday, and we now are troubleshooting various problems: the T1 connection to Barcroft is down, even though the dome Wi-Lan radio is working. Electric power is also off at the observatory dome - there seems to be short or some other problem. The Starband satellite connection is working at Barcroft, as is the T1 to Crooked Creek. We also just installed a new, higher bandwidth (2 Mb/s download, 500 Kb/s upload, with 5 static IP addresses) "Hughes Net" satellite internet service at Crooked Creek - details on how to access this later. The Crooked Creek Starband has been disconnected.

7/30/09 The lightning event destroyed or damaged at least nine devices, including internet switches, media converters, and digital pressure gauges. There is also damage to the dome power supply, either in the transformers or in the buried line. JTS is working on a write-up of the event.

June 2009. The 26th Annual Physiological Ecology Conference, was held at OVL on June 5-7, 2009. 13 presentations, including one by featured speaker John Harrison of Arizona State University, were given to the audience of 50 attendees.. See phys-eco web site for registration information and other details.

Student Minigrant Awards WMRC awarded 16 fellowships supporting graduate student research at the station, totalling over $20,000. See 2009 list of recipients. Recipients included 9 researchers from 5 UC campuses, in additon to 7 from other Universities.

April 2009. The 7th and final lecture of the Winter 2009 lecture series was held at the station on East Line Street on April 16. We had a very well-attended and successful 2009 seminar series. Our thanks go to organizer Denise Waterbury, the Friends of the White Mountain Reseach Station and the lecturers who donate their time. Details on WMRC public lectures web site.

Report from OVL....Christine Goedhart March 1, 2009

Figure 1– Measuring salt grass (Distichlis spicata) photosynthesis

This year in particular I am amazed at the change of seasons in the Owens Valley, and it gives me special admiration for the vegetation and wildlife that live here. I’ve been working in Owens Valley for three years now, but this is the first time that I’ve had field work during the winter. I didn’t think it was possible to miss the sweltering heat of the summer, but as I recently woke up to temperatures in the teens, I caught myself dreaming of long summer days under the scorching sun.

My dissertation project involves studying the effects of differing water and nutrient availabilities on vegetation in Owens Valley. In general, grass abundance is usually explained by water availability. However, at any given depth to watertable there is considerable variation in plant cover, suggesting that nutrient limitation may also play an important role. Indeed, we found that sites with greater grass cover had more soil nitrogen, and that grass photosynthesis was closely related to nitrogen availability. These results indicate that controls on nitrogen cycling may be an important determinant of grass distribution in this region.

Figure 2– Collecting leaves from an Ericameria nauseosa shrub

Watertable depths change radically throughout the valley, and lately I’ve been looking at how this difference in water availability affects the water transport system of dominant shrub and grass species. Surprisingly, although leaf carbon isotopes of the shrub species Ericameria nauseosa (Rubber rabbitbrush) showed increased plant water stress with increasing site watertable depth, there was no indication that the more water stressed plants had an altered water transport system to make them more water stress resistant. This pattern was also true for the shrub species Atriplex torreyi (Torrey’s saltbush) and the grass species Distichlis spicata (Saltgrass), where plants in sites with deeper watertables were not more water stress resistant. Currently, I’m focusing on how depth to watertable and soil nutrient availability affect plant chemical and nutrient composition.

What a wonderful opportunity it has been to work in such a beautiful location! While in the field I sometimes take breaks to gaze at the snow-capped mountains and reflect on how lucky I am to be out here this time of year. Although I might not think so when I first wake up, being able to see Owens Valley in the winter is definitely worth having to pile on the extra jackets in the morning.

Report from Crooked Creek....Adelia Barber August 31, 2008

This week, I returned to Crooked Creek after a few weeks away, and the chilly weather of fall has arrived in full force! The wind outside is blowing so hard that the metal roof at the station is making strange howling noises. I spent most of the early summer up here as well, and with the help of a few dramatic thunderstorms it’s been an idyllic season in the White Mountains. This is my third season at Crooked Creek working on my dissertation research, which is focused on the population dynamics of bristlecone pine trees in several groves around the station. For this trip, I’m joined by some excellent field assistants, some of whom are designing their own projects on seed predation and seedling survival.

Picture 1: Five small bristlecone pine seedlings emerging under a log near Patriarch Grove

This year, we’ve discovered some exciting things. First, of about 10,000 seeds that we placed out in protected cages over the winter, about 30 tiny seedlings germinated and a few are still alive after the hot, dry summer. We also spent a week of the early summer on our hands and knees, looking carefully under every rock in an attempt to find naturally germinating seedlings. After searching in many different areas, we had found only 9 trees total. Interestingly, 5 of these trees are all germinating together under a piece of wood near Patriarch Grove, suggesting that a small mammal or bird may have cached some seed and forgotten about it over the winter. All told, we’re discovering that bristlecone seedlings are very, very rare, despite the fact that millions of seeds are produced each year. However, our calculations of population growth rate indicate that the total numbers of trees are actually increasing (despite the low success rate of the seedlings) simply because these trees live for so long.

Picture 2: Team Bristlecone posing near a spectacular tree we call the “old sucker”

Myself, and the rest of “Team Bristlecone” are now settling nicely back into the routines of research station life. Every morning we hike out into the bristlecone groves, we wave “hi” to Campito the wild horse and begin a long, fun day of looking for seedlings, counting cones, and mapping trees. We hike back at the end of day, completely exhausted, and are treated to the wonderful creations of our two chefs Tim and Lisa.


August 3, 2008 Over 400 people attended the annual Open House at Barcroft. Our thanks to the WMRC friends' group for assisting. See Lecture Schedule and Photo for more details.

June 15 Barcroft report from Thea Wang*!

I am back at Barcroft Station for a third summer season. I spend summers here collecting data for my four year PhD thesis research project. My study is on the social behavior of yellow-bellied marmots (Marmota flaviventris). I am specifically looking at marmot social structure and how behavior is distributed among group members. I am focusing on four types of behaviors. These include positive and negative social interactions, alarm calling (antipredator defense) and the first marmot to emerge from the burrow in the morning. I have individually marked marmots from six different colonies around Barcroft Station. I use small metal ear tags for long-term identification and black fur dye for long distance identification. Interestingly, I have trapped marmots that already have ear tags. These are probably from Bette Stallman’s previous marmot project on marmot foraging preferences that concluded in 2001. Marmots can live for up to 17 years so it is not that surprising that I found them.

So far this year at Barcroft has been a little different from the previous two. I still have a field assistant and I still have Dori the cook but this year the road is blocked with snow and we had to ride in the snow cat to the station. Even with the snow, most of the marmots are above ground and not hibernating. The first few days up here were pretty slow as the weather was cold and windy and not much was happening. But now it is balmy with temperatures in the 50s and there is tons of marmot action for us to observe. There are other animals around including ground squirrels, chipmunks, birds and hares but no pikas yet. My field assistant and I have started a routine that will be the same for the rest of the season… waking up before the marmots (around 5 AM), taking marmot behavioral observations and trapping for the rest of the day.

WMRC annual butterfly count sets North American record! Plebejus shasta, the Shasta Blue (photo at right) was super-abundant at 12,700' elevation and above during the 2007 summer butterfly count. Our team of 4 counters recorded 875 individuals in about 30 minutes of counting. Large numbers of these butterflies were also seen in August of 2006 at the 13,000' level. This record eclispes the previous record of 230 in 24 hours by a wide margin. This result, after only three years of counting, suggests some unique characteristics of the high alpine habitat surrounding the Barcroft Field Station. It also illustrates the value of targeting the high alpine habitat for sampling. For more information about the annual butterfly count, see WMRC 4th of July butterfly count pages.

2006 news

WMRC-affiliated astronomer George Smoot wins Nobel Prize for his work on the origins of the universe! Using extraordinarily sensitive instruments developed and tested in the dry air at WMRC Barcroft Field Station, in balloon flights, at the South Pole, and in the COBE (Cosmic Background Explorer) satellite, UC Berkeley Professor George Smoot and coworkers (see Smoot Group web site) discovered tiny ripples in the Cosmic Microwave Background Radiation (CMB). The brightness and pattern of these ripples have helped define modern theories about the age, composition and origin of the universe. Dr. Smoot's work built on a long history of cosmology research carried out at WMRC facilities, particularly Barcroft.

Some of the early measurements of the CMB were made at Barcroft in 1966 by UC Berkeley radio astronomers Jack Welch, David Cudaback and colleagues. In 1967 the MIT group headed by Bernard Burke, and independently, the Princeton group with cosmology pioneer David T. Wilkinson came to Barcroft and made crucial measurement of the CMB spectrum. In 1969 and 1971 research teams from the Aerospace Corporation and UC Berkeley (led by Paul Richards and including Dr. Smoot's co-Nobel laureate John Mather) made a set of crucial observations confirming the blackbody spectrum of the CMB. These findings led to a major program involving balloon flights and rocket-borne instruments. Dr. Smoot's team began working at Barcroft in 1980 and returned most summers throughout the 80's, testing and refining instruments and taking measurements. For a more complete story, read "The spectrum of cosmic background radiation: early and recent measurements from the White Mountain Research Station" by George Smoot, and "25 Years of High Altitude Research" written by WMRC' founder Nello Pace.

For more information see 45 minute web cast of Professor Smoot's Nobel Prize lecture. Here is a quote from Dr. Smoot's Nobel Lecture (see Rev. Mod. Phys. 79, 1349–1379 2007) in which he credits WMRC with a key role in the early development of cosmology in the 1970's:


Shortly after the Penzias and Wilson discovery and initial estimate of the CMB temperature, there were a number of observations and determinations or estimations of the temperature at various wavelengths which were the beginnings of the effort to establish that the CMB spectrum was blackbody. David T. Wilkinson and Peter Roll were pioneers in radiometric observations beginning on the roof of Jadwin Hall at Princeton. Wilkinson and colleagues, first Stokes and Partridge continued with a set of long wavelength observations from the White Mountain Research Station in California. This is a high altitude site operated by the University of California and one that is a good site for CMB observations because of its high altitude (12,000 ft, dryness, and reasonable accessibility via a road that is open for about half the year). As mentioned above, by 1974 Professor Paul Richards began a program taking on graduate students, John Mather and Dave Woody. Richards’ program developed bolometers and a Michelson interferometer for spectrum observations and these are the precursor for COBE FIRAS. The FIRAS ((Far Infrared Absolute Spectrophotometer) instrument design came directly from the original White Mountain instrument, which was then morphed to be the Woody and Richards balloon-borne instrument. The FIRAS team, led by John Mather, studied the results and performance of the Woody and Richards instrument and experiment and designed FIRAS both to be as symmetric as possible and to operate at the same temperature as that from the sky input. Another key feature was the sky simulating blackbody which was carefully designed, crafted and tested to be a very good blackbody at a well-defined temperature.

Cosmic origins research continues at WMRC to this day under the direction of one of Professor Smoot's former students, UC Santa Barbara Professor Philip Lubin. The Lubin group continues to design, build, test and operate instruments that look back to the early universe. See WMRC Astrophysics web site for details.


GLORIA "Master Station" at WMRC The University of California White Mountain Research Center (WMRC) hosted a GLORIA planning workshop at the Owens Valley Labs on May 22, 2006, and 16 scientists attended (GLORIA stands for the Global Observation Research Initiative in Alpine Environments). The primary outcome was a commitment by the group and the WMRC to establish a "GLORIA Master Station" at WMRC, dedicated to investigating the high elevation environment surrounding the seven White Mountain GLORIA summits (see WMRC-GLORIA web pages for details). A second outcome was a tentative plan to host a conference and produce conference proceedings as early as fall 2007. Finally, the group created a working plan for this summer's WMRC-GLORIA field week, held at Crooked Creek Station during the week of July 22-29, 2006.


OPEN GATE DAY SUNDAY, September 3. The gate to the Barcroft Station will be opened for those wishing to climb White Mountain Peak. You may drive to Barcroft, park, and hike up to the peak. Please be advised that the Barcroft research facility will not be opened to the public on this day, and please do not disturb staff or researchers at the station. You will be at high altitude and if you experience any health problems, go down immediately.

Even though the station will be closed to visitors, there will be a team of medical researchers asking hikers if they will volunteer to be interviewed and monitored for symptoms of acute mountain sickness. The results are part of an effort to understand the health implications of travel to high altitude.

2003 news

November 2003 UCSD television is working on a feature-length documentary about the station. The web page shows some of the progress.

October 2003 In collaboration with the Western Regional Climate Center, we installed a new on-line weather station at the summit lab on White Mountain Peak. It is now North America's highest-altitude weather station! We also have installed a similar on-line station at Barcroft and have plans for one at Crooked Creek.

December 2003 Barcroft station is supporting full winter operations for the first time in many years. Two staff are in residence at the station, taking care of animals and keeping the station open. Winter research projects include animal physiology, growth and development at high elevation, astrophysics, millimeter-wave astronomy, atmospheric studies, and others. The Barcroft staff are in turn being supported by the Bishop staff, who are making weekly sno-cat runs over the snow-drifted roads, to bring in supplies, investigators, and staff shift changes. illustrate one such trip. Researchers who wish to ride in on the snocat trips should call the station for details, and tentative trip dates have been scheduled (but please note that safety and staffing needs have priority and that the trip schedule is subject to change without notice).
