The cause of a gas leak that forced an evacuation of Snowmass Base Village for part of Tuesday was unknown as of Tuesday afternoon, according to the gas company investigating the incident.

The evacuation was ordered around 9:20 a.m. via Pitkin Alert and other public channels. According to a press release from the town of Snowmass Village, approximately 175 people were asked to leave all Base Village properties, including the Limelight Hotel, Capitol Peak, Hayden Lodge, Lichenhearth and Tamarack properties. The Snowmass Village Police Department set up a check-in and check-out area for people to enter the area briefly to retrieve valuables, but vehicles were not accessible, due to the risk of gas ignition, according to the police department.

Responders from Roaring Fork Fire Rescue, Pitkin County Sheriff’s Office, Basalt Police Department, the town of Snowmass Village and the Snowmass Village Police Department all responded to the scene. Black Hills Energy also responded to the scene, once fire crews confirmed that there was no risk in attempting to stop the leak, according to a press release from Black Hills Energy.

Just before 1 p.m., the leak was stopped, and once Roaring Fork Fire Rescue confirmed the gas levels were safe, evacuees were allowed to return to the area.

According to the press release from Black Hills Energy, the cause of the leak is not yet known, but crews will continue to investigate the cause.
