CODY, Wyo. (AP) — It may be months before search and rescue members can reach a single-engine plane that crashed on a mountain in northwest Wyoming.

The two elderly brothers from Alabama and Washington were on board the aircraft. They are presumed dead based on aerial views of the crash site on a rugged, snow-covered mountain just outside Yellowstone National Park.

The Park County Sheriff's Office says the danger of avalanche makes it too risky to put people on the ground to recover the bodies and the plane

Sheriff's Office spokesman Lance Mathess says it could be two weeks or two months before the avalanche danger ends and the deep snow melts enough to allow recovery.

The brothers were headed from Cody to Twin Falls, Idaho, and then to Seattl


CODY, Wyo. (AP) — Officials have found a single-engine plane that was missing.

The Park County Sheriff Office says the crashed plane was found Monday morning on a rugged, snowy mountain just outside Yellowstone National Park. It was carrying two brothers in their 80s.

The fear of an avalanche has prevented rescuers from reaching the crash site, which is at about 9,900-foot elevation. So officials can't determine the condition of the occupants.

The 1963 Mooney M20C was last seen last Tuesday departing Yellowstone Regional Airport in Cody. On board were 84-year-old Robert Zimmerman of Huntsville, Alabama, and 86-year-old Ward Zimmerman of Seattle. The plane was reported missing Saturday, and the search began Sunday.
