Search for U.S. Senator Mark Udall's brother, Randy Udall, continues in Wyoming's Wind River Range

James "Randy" Udall didn't return from hiking trip

PINEDALE, Wyo. - Helicopters and ground crews are again searching Wyoming's Wind River Range for the brother of Colorado Sen. Mark Udall.

James "Randy" Udall failed to return from a solo backpacking trip as planned last week.

Thirty searchers from multiple agencies were looking for signs of the 61-year-old over a 225 square mile area, the same region they've been searching since Friday. Sublette County’s contract helicopter was over the search area Tuesday, along with a helicopter of the Air National Guard. A third helicopter was expected to join the aerial search, according to the Sublette County Sheriff’s Office.

Udall is an alternative energy advocate and environmentalist from Carbondale, Colo. He's an experienced backpacker who has hiked the Wind River many times over the past 30 years.

He signed in at the popular Elkhart Park trailhead on June 20. Sublette County sheriff's spokesman Stephen Smith says it's a well-marked trail over rolling country that starts at 10,000 feet.

He is described as 6 feet 4 inches tall, 200 pounds with gray/brown hair and blue eyes. If you have been in the Wyoming backcountry recently and have seen a man matching this description, contact the Sublette County Sheriff’s Office at (307)367-4378.
