Emergency officials are working on recovering the body of a man who died near a technical area of Wichita Mountain known as Falcon Ridge.

The Summit County Sheriff’s Office and Summit County Rescue Group have set up an operations center near North Tenmile Creek trailhead, which is at the west end of Main Street near Frisco. Wichita Mountain is a roughly 10,850-foot peak west of Interstate 70, near Exit 201 known for its craggy terrain.

The man was reported missing from Frisco last night, according to a Sheriff’s Office Lt. Mike Schilling. He said some of the man’s friends were looking for him last night and found his bicycle near the trailhead.

“Rescuers went out last night and ultimately were able to locate the deceased,” Schilling said, “But it was getting dark, and with the weather that was moving in, it wasn’t safe to attempt a recovery last night.”

The body recovery operation is unrelated to the search for Sean Marquardt, who was reported missing from Vail in early May. Anyone with information about his whereabouts since Friday, May 9, should call the Vail dispatch number at 970-479-2201.

Schilling said the body recovery will take most of the day, as rescuers will have to hike up rocky terrain and use rope systems to perform a technical recovery. The operation will not utilize helicopters or other air assistance.

While Schilling said the rescue area is only about 1.5 miles from the trailhead “as the crow flies,” the terrain will make the hike to the area take significant time.

The man was wearing tennis shoes, Schilling said, so deputies suspect he was hiking or running.

“He’s known to recreate in this area often,” Schilling said. “We believe he was out on a hike or a run and had some sort of an accident.”

Conditions on Wichita Mountain are mixed this time of year, with dry conditions at the trailhead and snow, especially in shaded areas, at higher elevations, Schilling said.

“Our hearts are with the family, friends, and loved ones of the individual during this difficult time,” Summit County Sheriff’s Office officials stated in a press release. “Please utilize other areas for recreation today to give our responders the space needed to complete this work safely, with care and dignity.”
