PINEDALE, Wyo. (AP) — An accidental fall was apparently what killed a climber found dead on Wyoming’s highest mountain, according to the Sublette County Sheriff’s Office.

A helicopter crew spotted the body of Thor Hallingbye, 41, of Cheyenne, shortly after noon Monday on Gannett Glacier. The glacier is at nearly 13,000 feet (3,960 meters) on 13,810-foot (4,210-meter) Gannett Peak.

“This appears to be a tragic climbing accident and our deepest condolences go out to the friends and family of Mr. Hallingbye,” sheriff’s office spokesman Sgt. Travis Bingham said in a statement.

Hallingbye’s body was flown from the mountain to the Lander airport. The Fremont County Coroner’s Office was investigating, the Casper Star-Tribune reported.
