Out of the office and up Denali!
July 2004
By Amy Hartley,
Installing a weather station at 19,000 feet is rough duty, but two men from UAF recently
left their offices on campus to climb almost to the top of North America's highest
peak and get the job done.
Kevin Abnett, a software engineer from the university's , and Tohru Saito of the , scaled Denali--the traditional Athabascan Indian name for Mount McKinley. They were out for 20 days as they hauled and then installed 20 pounds of equipment at an outcrop just south of the peak's summit. The weather station--an upgrade and replacement for one installed earlier which malfunctioned and was no longer transmitting data--will record wind speed and direction, relative humidity, barometric pressure and temperature.
For Abnett, the opportunity to climb Denali allowed him to witness first-hand the
extreme weather conditions his equipment is expected to withstand. During storms the
winds on the mountain are typically greater than 100 miles per hour with winter temperatures
as low as 60 degrees below zero Fahrenheit. The weather station recorded an unofficial
wind speed of 188 miles per hour three days before it stopped working in January 2003.
"In 2002, when I first got the invitation to go, I said, 'No--absolutely not! I prefer oxygen in the air I breathe!'" Abnett said. "It sounded so ridiculous to me at the time, I declined. But as I started to think about it more, I realized I wanted to understand the conditions on the mountain better, so I decided to make the attempt this summer."
For months, Abnett trained for the climb. He hiked the Fairbanks area with a large
pack and took a mountaineering class. He was in good physical condition, but before
leaving he was understandably anxious.
"The physical endurance required at altitude was the most challenging," Abnett said. "I just couldn't seem to get enough air in my lungs, especially carrying a 40-pound load. No matter how hard I breathed, it just wasn't enough. After a few days of acclimatizing it was better, but still difficult."
This was the third trip up Denali for Saito. He's worked on the weather station project
since 2002, when the first equipment which transmitted data was built and installed.
From his cubicle in the International Arctic Research Center, Saito helped coordinate
the trip's logistics and translated for participants from Alaska and Japan. Saito's
involvement was crucial because the expedition was led by Japanese mountaineer Yoshitomi
Okura and aided by members of the Japan Alpine Club.
Having been up the mountain before, Saito was supportive of Abnett. He and Abnett hiked together and practiced rope-climbing, and he explained what Abnett could expect.
"Getting to know someone before you go is important," Saito said. "When you're doing something like this, it's you against the mountain. It's you against all those elements, so it's nice to have someone you know there to help you."
"The Japanese climbers were just great," Abnett said. "They helped me out many times on my way up there."
Abnett set the weather station equipment up at the 14,000 foot medical camp on June 22, 2004 and ran some tests. On June 27 the Japanese crew climbed to 18,735 feet and assembled the equipment at its permanent location, then continued to the summit. The whole team was down at Kahiltna Base Camp by June 30, when more tests confirmed the weather station was transmitting as intended.
"We're receiving the signal just fine in Fairbanks now," Abnett said.

Weather data for everyone
The Mount McKinley weather station project got Abnett and Saito off campus and into
the extreme, but the crux of the project is to provide critical information about
a location that is little known or understood. The UAF team hopes to enhance current
forecasting methods atop the mountain with this station, which will provide current
weather data by sending a transmission with the latest information back to the International
Arctic Research Center every 30 minutes. The data will also be listed online around
the first of August, so anyone in the world can key in its address and find out what's
happening atop Denali. The Mount McKinley weather station website is www.iarc.uaf.edu/mt_mckinley_weather.php
