A climbing accident has killed two men in Wyoming's Wind River Range, marking the second double climbing fatality in the state in a week.

Fremont County Undersheriff Ryan D. Lee says another nearby climber saw the two men fall several hundred feet down the face of Pingora Peak on Friday afternoon.

The Fremont County coroner's office identified the victims as 23-year-old Jonathan Peter MacDonald, of Lander, Wyoming, and 57-year-old Keith Murray Henderson, of Cheyenne.

Lee says it appears the two men were rappelling down the 11,884-foot peak when they fell. Investigators are inspecting their climbing gear.

Two women died in a simultaneous fall at Grand Teton National Park on Aug. 22. Officials say 28-year-old Tyler Strandberg and 27-year-old Catherine Nix fell 200 feet.
