Search resumes in Wyoming's Wind River Range for brother of Colorado Sen. Mark Udall

CHEYENNE, Wyo. — A wilderness search for James "Randy" Udall, whose family is well-known in Western politics, continued Tuesday with no sign of the environmentalist and energy efficiency advocate overdue almost a week from a solo backpacking trip in the shadow of Wyoming's highest mountain.

Udall is a brother of Colorado Sen. Mark Udall, cousin of New Mexico Sen. Tom Udall, and son of the late Arizona Rep. Morris "Mo" Udall. His uncle, Stewart Udall, was Interior secretary in the 1960s.

Dozens of searchers on the ground and in two helicopters were looking for Udall in a 225-square-mile area of the Wind River Range southwest of 13,809-foot Gannett Peak.

Udall, 61, left June 20 from a trailhead 10 miles northwest of Pinedale in western Wyoming. He was due back last Wednesday. The search for him began Friday, the day he was reported missing.

The Wind River Range sprawls 100 miles southeast of the Yellowstone ecosystem and jags the horizon of the nearby sagebrush country like saw teeth.

Compared to other wilderness areas in Wyoming, the area's maze of trails is popular with summertime backpackers and day hikers. Many who explore the area venture off-trail to fish or climb, said Rick Rochelle, director of professional training for the Lander-based National Outdoor Leadership School.

A well-known wilderness training academy, NOLS currently has 29 groups of 14 students and instructors participating in courses in the Wind Rivers. Groups headed into the mountains were being told to keep an eye out for Udall. Half a dozen NOLS employees joined the core search party Tuesday, he said.

"You can't see through the forest canopy to see the ground, if you're searching from a helicopter," Rochelle said. "So you need people on the ground to search that kind of area."

Thin air and slick snowfields are challenges higher up, said Rochelle, who has taken part in search efforts in the Wind River Range over the years.

One thing going for Udall: The weather has been warm, with nighttime temperatures dipping to freezing only at the very highest elevations.

"It's been pretty comfortable conditions out there," Rochelle said.

Sublette County authorities described Udall as an experienced hiker and no stranger to exploring the Wind River Range over the past 30 years. Even so, the rugged winds claim even experienced hikers and climbers with disturbing frequency.

In 2006, Wyoming's chief state public defender, Kenneth Koski, 56, died on 12,585-foot Mount Bonneville about 60 miles southeast of Pinedale. Koski was alone and apparently fell more than 400 feet during a climb.

In 1998, Idaho pastor Mike Turner, 48, became trapped between two boulders while backpacking on the east side of the Wind River Range. He used a cup attached to a rope to try to fetch water from a nearby pond. He wrote at length in a diary about his ordeal and survived nine days before he perished.

Udall is an author and helped found the Community Office for Resource Energy Efficiency, a nonprofit group that promotes the use of renewable energy in the Aspen, Colo., area.

Under a program Udall helped create, people building large homes in the Aspen area pay an energy fee which is then used to pay for rebates for energy reducers like efficient appliances or solar power systems, said Mona Newton, the office's current director.

Newton said her staff members are optimistic and hopeful Udall will be found healthy and safe.
