BOULDER COUNTY, Colo. — A body believed to be that of a female cross-country skier was discovered at Brainard Lake on Thursday morning, the Boulder County Sheriff’s Office said.

Officials said someone called about 10 a.m. to report the discovery of the woman at the west end of a ski trail.

Deputies hiked one hour from the trailhead off the Peak to Peak Highway about 12 miles north of Nederland to the lake to confirm the discovery.

The sheriff’s office, Rocky Mountain Rescue Group and the Boulder County Coroner’s Office used snowmobiles to recover and take the body from the recreation area.

The coroner’s office will determine the cause and manner of death and release her identification. No foul play is suspected.

The Brainard Lake Recreation Area is popular with hikers and cross-country skiers. The lake is at 11,355 feet in the Indian Peaks Wilderness Area.
