One snowboarder fell off the Montezuma Express chairlift around 1:30 p.m. on Nov. 13 and was transported to the hospital, according to Lee Rasizer, a public information officer for the Colorado Passenger Tramway Safety Board.

Keystone Resort filed an incident report with the safety board the day of the fall, Rasizer wrote in an email, which it is required to do when someone falls outside of the loading or unloading zone and injuries are involved.

The incident report attributed the fall to skier error and stated it was not related to any mechanical failure, Rasizer wrote, meaning the board will not be producing its own report.

Rasizer wrote that the snowboarder fell about 35 feet while between towers four and five of the Montezuma Express chairlift. The lift stopped at the request of ski patrol “immediately,” Rasizer wrote, and reopened about 27 minutes later after lift maintenance staff completed an inspection.
