Authorities in Pitkin County on Tuesday recovered the body of 64-year-old skier John Martin Gancsos, who was killed in an avalanche near Aspen Mountain on Monday afternoon.

The Pitkin County Sheriff’s Office said he was best known to residents as “Marty.”

Gancsos’ body was recovered early Tuesday by Mountain Rescue Aspen. Search crews evaluated the avalanche risk in the area where the fatal slide happened and determined it was safe to search for and locate the victim.

The avalanche happened at about 3 p.m. in the Castle Creek Valley area outside of the boundary of Aspen Mountain ski area.

According to the county sheriff’s office, officials were notified shortly before 3 p.m. that two skiers were involved in the snowslide. One of the skiers provided information on their location to rescuers from the sheriff’s office as well as the Aspen Mountain Ski Patrol and Mountain Rescue Aspen.

The Sheriff’s Office said Gancsos’s body was discovered just after 4 p.m. at the bottom of a snow-covered chute at approximately 9,400 feet. He was pronounced dead at about 5 p.m. The cause/manner or death will be released by the coroner’s office after an autopsy.

The Colorado Avalanche Information Center said the slide happened below treeline.

The Aspen area received several inches of new snow with the storm last week that buried the state. Resorts in the area were warning skiers and snowboarders not to enter closed terrain because of high avalanche danger.

The CAIC says avalanche danger remains “considerable” across the state.
