Authorities closed the Frisco Scenic Overlook on westbound Interstate 70 for about two-and-a-half hours Wednesday as they investigated a man's death at the popular pull-off site.

Colorado State Patrol Sgt. Pat Williams confirmed the deceased man was a white male in his 50s but would not release his name, pending the notification of the man's family.

Williams said police were called to the overlook shortly after 9 a.m. to check on a black Ford Focus that had been left there for a few days. Inside the snow-covered car they found the man's body.

According to CSP, he was in the driver's seat, and he was the only one inside the car.

The license plates on the car also were associated with a missing-persons report out of Denver, according to Williams, who said Colorado State Patrol and Denver police are currently working the investigation together.

"Right now, it appears to be no suspicious circumstances," Williams said, adding that further details will not be released at this time.

According to the Colorado Department of Transportation, the overlook reopened at 12:40 p.m.

CDOT, Frisco police, Denver police and Lake Dillon Fire Rescue all either responded to the call or assisted with the investigation.
