WMRC Director’s Research on the Eastern Sierra
Gains National Press Attention
A study published in Nature.com/Scientific Research by WMRC Director
Glen MacDonald and an international team of scientists has gained na-
tional attention in the Washington Post, Christian Science Monitor, San
Francisco Chronicle, the Los Angeles Times and many other print, radio
and television outlets.
The research, based on the analysis of the sediments from Kirman Lake
in Mono County near Bridgeport, shows that past prolonged episodes of global warm-
ing produced la Nina-like conditions in the Pacific Ocean and resulted in long periods of
drought in California. These arid episodes extended from decades to thousands of years,
depending on how long the warming persisted. “Radiative forcing in the past appears to
have had catastrophic effects in extending droughts,” said MacDonald, an international
authority on drought and climate change. “When you have arid periods that persist for
60 years, as we did in the 12th century, or for millennia, as we did from 6,000 to 1,000
B.C., that’s not really a ‘drought.’ That aridity is the new normal.” Read more below:

Weather Station Network along the Piute Creek Drainage

S ince late 2006 we have maintained a network of seven weather stations in the White Mountains. The lowest
elevation site is located at Fish Slough in the Volcanic Tablelands north of Bishop and west of US Highway 6. The
remainder of the transect is laid out east of the highway along the Moulas Mine jeep trail in the Piute Creek Drainage
on the west slope of the White Mountains. Including Fish Slough, the sites span an elevational gradient from 1289 m
(4228 ft.) to 3121 m (10,240 ft.) in roughly 333 m (1000 ft.) increments (Figure 1). Most of the sites are located in a
desert ecosystem, and the upper two sites extend into a sparse conifer region.
A ccessing the stations via the jeep trail is a challenge as the rocks are particularly unforgiving and are adept at
cutting through the sidewalls of tires with ease. On a recent journey up the road a new field worker could not
understand why the truck was stopped so frequently to move seemingly arbitrary rocks off the trail since the trail was
covered with rocks. After getting a flat at just about the highest point traveled on the mountain, he became a believ-
er and was first out of the truck whenever trail maintenance was required. We average at least one flat tire per trip.
(Figure 2).
E ach of the weather stations measures air temperature, hu-
midity, wind, precipitation, solar radiation, barometric pres-
sure, soil moisture and soil temperature. The installations were
designed for durability, low power consumption, data storage
and transmission, and affordability. The meteorological instru-
ments are mounted on an aluminum pole (Figure 3) with soil
sensors buried below ground. The data sampling, storage and
wireless communications are managed by a DL4-Met data log-
ger that was developed in-house by Douglas Alden at SIO. The
logger records one minute averages of air temperature, humidi-
ty, barometric pressure, solar radiation, and winds. Precipitation
is recorded as a running sum while soil temperature and

soil moisture are sampled at one hour intervals. The stations are powered by a small 6A-hr battery recharged with a
5W solar panel. Data are stored locally on a SD memory card. Each logger transmits a subset of these data every 30
minutes to the White Mountain Research Center, Owens Valley
Lab, where they are forwarded via the internet to a server at SIO
for archiving.
T he network seeks to inform issues relating to weather, cli-
mate variability and climate change that arise along the west
slope of the White Mountains. The White Mountain network is
an extension of a large-scale network in the Sierra that we main-
tain in cooperation with the California Snow Surveys unit of the
California Department of Water Resources. The network runs
along the highway 120 corridor from Priest Reservoir in the west,
across Yosemite National Park, over Tioga Pass and down
through the Inyo National Forest to Lee Vining, California. The
combined network seeks to understand how climate and its fluc-
tuations change within the air masses that move across the Sier-
ra Nevada and up into the White Mountains.

Altitude Sickness Prevention and Efficacy of Comparative
Treatments (ASPECT)
Story and photos courtesy of Dr. Grant Lipman, MD, Stanford University
H uman beings are getting smarter about traveling to high altitude. The incidence of acute mountain sickness
(AMS) is now half of historical norms at the most popular trekking routes on the Everest approach and on the
Annapurna circuit, researchers at the Himalayan Rescue Association
are seeing one case of AMS every other day. The distressing con-
stellation of symptoms that comprise AMS (headache, sleep dis-
turbance, fatigue, dizziness, and gastrointestinal distress) often re-
solve within 1 to 2 days after arrival at high altitude. However, the
disease can be debilitating, ruin an adventure, and, if left unrecog-
nized or untreated, can progress to potentially fatal high altitude
cerebral edema.
W hile the decreasing rates of AMS is great news for trekkers,
the lower incidence of AMS negatively affects power calcula-
tions and makes it nearly unfeasible to run large clinical trials. So
where in the world can one go to study altitude illness? Certainly a
trip to Mt Kilimanjaro with over 50,000 annual visitors and a terrify-
ing 40 fatalities a year is ripe for education and interventions, but
the lack of infrastructure and logistical challenges of Tanzania
makes it a daunting venue. Colorado is a great option complete
with a drive-up 14er, but baseline acclimation of Denverites and the
lack of high altitude lodging have made things difficult. Alternative-
ly, the White Mountain Research Center (WMRC) in California has
been serving up an approachable and comfortable option for high
altitude research for nearly 60 years. Established in 1950 just outside
of Bishop, California, WMRC has stations at 4,100’, 10,200’,
and 12,500’ and located on the flanks of White Mountain; the
3rd highest peak in California at 14,252’ with a gorgeous
ascent path.
W ith the generous support of the American Alpine
Club’s 2015 Research Grant, Wilderness Medical Socie-
ty’s Herbert N. Hultgren Grant, and the Institute for Altitude
Medicine, in August 2016 we studied the inhaled asthma
medication budesonide for AMS prevention compared to the
standard AMS prophylactic acetazolamide (diamox) versus
placebo. This was a dou-
ble blind and random-
ized, placebo controlled
trial. Considered the
most rigorous type of research
methodology, the trial was run by Stanford Wilderness Medicine.
A SPECT enrolled 103 participants, resulting in the largest North American
AMS prevention trial to date. We witnessed AMS rates from 56% to 72%,
with severe AMS of 46%. Imagine the worst hangover of your life replete with
Dr. Lipman and a study participant suffering from AMS at

pounding headache, stupefying nausea, and
a rapid resting heart rate with low oxygen
levels that would set off alarm bells in a sea
level emergency room. That is severe AMS .
W hile budesonide did not appear to
work any better than a placebo, dia-
mox worked wonders, especially on prevent-
ing severe disease. This was significant both
statistically and clinically with a 20 – 30%
reduction of disease over both placebo and
budesonide. The laboratory space, off-grid
infrastructure, and broadband internet ac-
cess at 12,500’ Barcroft Station, allowed us
to run ultrasound testing and pulmonary
function tests to analyze the physiologic
changes seen with rapid ascent to high altitude. Having study participants provide forced expiratory tests in a low
oxygen state made all the researchers profoundly appreciative of the volunteer’s time and effort! The initial analyses
point to increased total body water in those suffering
from AMS, findings that may provide greater insight
into causation of the disease itself.
D iamox (125mg twice / day) is usually ingested the
night prior to ascent to allow time for maximal
effect. Interestingly, ASPECT was one of the few studies
to examine diamox beginning the morning of ascent, in
a rapid ascent profile (4,100’ to 12,500’) that is common
for most hikers, climbers, as well as tactical and search
& rescue personnel. The robust protective effect of dia-
mox in this setting is generalizable to ascents found in
the continental US and Western Europe, which may al-
low diamox to be utilized in a new manner. Further-
more, diamox appeared to work as well as ibuprofen
(600mg taken three times a day, started morning of as-
cent), at the same altitudes which was the subject of our
prior study at WMRC; the Prevention of Altitude Illness with Non-steroidal anti-inflammatory Study (PAINS).
W hile the potential for a new pre-
vention in budesonide appears to
be a non-starter, we were able to confirm
the rates of AMS at WMRC that perhaps
will make this an epicenter of future high
altitude clinical trials. Every study often
poses more questions than answers, and
future work may find us comparing dia-
mox to ibuprofen to make definitive con-
clusions of the efficacy of these two popu-
lar drugs.

Daniel Pritchett, long-time WMRC staff member, Retires
Daniel Pritchett, WMRC’s longest serving staff member, is retiring after almost 20 years as the
Center’s information technology specialist and historian. He began work at the Center as a vol-
unteer in 1996 and was hired the following year. Daniel developed the WMRC computer labora-
tory in the early 2000s and has maintained individual work stations for staff during his time here.
He has been instrumental in developing and maintaining internet capabilities, particularly at the
high elevation laboratories. One of his greatest accomplishments at WMRC was designing the
new telecommunications system to the upper stations, in collaboration with Noley Baker, and
Jeremiah Eanes; a daunting and very challenging task.
When asked about a memorable experience he reflected on a snowmobile adventure to the Bar-
croft Station in the late 1990’s with then WMRS manager, David Trydahl. After having to dig out
the machines from deep snow, having engine difficulties and getting disoriented, they made it
to the Barcroft Station. Daniel was so smitten (or hypoxic) with himself making it that far, he
thought he would quit his new job to become a professional snowmobiler! However, once back
down to Sierra View the reality of being coated with exhaust and ringing in the ears from engine
noise changed his mind. He ended up working at WMRS/WMRC for over 19 years instead.
Daniel has a strong interest in the history of WMRC, the White Mountains, and our surrounding
high desert environs. His column, ’From the Archives’ in the spring newsletters are often historical
accounts of WMRS (now WMRC). Fortunately, for WMRC, Daniel plans to volunteer in working with the WMRC archives. He
comments, “There is a lot of interesting WMRS history that cries out for publication.” He would like to see the holdings of the
WMRC archives described in a standard digital format so they could be searchable through the Online Archive of California. He
will continue to work with a consultant to do an evaluation of WMRC facilities for eligibility for listing on the National Register of
Historic Places. Last but not least, WMRC will be receiving Doug Powell’s papers and photos and this material will need to be
described and organized. Everyone at WMRC wishes Daniel a fulfilling and adventurous retirement!
Big Pine Paiute Tribe, USFS and WMRC
share a Cultural Exchange Day
The Big Pine Paiute Tribe of the Owens Valley invited WMRC staff
to attend a field trip into the White Mountains in early August.
In attendance were: about twenty Tribal representatives, includ-
ing youth and elders; Paiute Tribe Environmental Director, Sally
Manning; USFS Archeologist Jacqueline Beidl; Assistant Forest
Archeologist Ashley Blythe; Archeological Technician Krystal Kis-
singer; and WMRC staff members Daniel Pritchett and Denise
Waterbury. Manning said, “The purpose of the trip was to share
perspectives on the long-term relationship between humans and
the White Mountain range while exploring as a group, some of
the beautiful places in the White Mountains.” We visited the cul-
turally significant pinyon-juniper woodland and Schulman Grove.
Forest Service archeologists spoke about geography and human
use of the range, and Daniel Pritchett shared a brief history of
WMRC and discussed some of the important research performed
at the research station. After lunch at the Crooked Creek Sta-
tion, everyone took a walk. Tribal Elder, Ross Stone, shared sto-
ries, and along with Tribal youth, sang two traditional songs of
the mountains. Everyone enjoyed sharing camaraderie,
knowledge, and being outdoors in the White Mountains.
