A 19-year-old woman died Friday at Vail after a ski jacket was caught in a chairlift and pulled down into her body, authorities say.

The accident occurred at the intermediate 6-acre Snow Shovel trail at about 3:30 p.m., according to the Summit County Sheriff’s Office.

Sheriff’s deputies, rescue personnel and the Vail Resorts’ Flight for Life helicopter team responded to the mountain after receiving reports of an on-site patient, according to a news release. Responders worked to free the woman, who was then flown to the Vail Medical Center in nearby Frisco, where she was pronounced dead.

“This was an all-out team effort involving Avalanche Rescue Team members, including their help with extricating the patient from her jacket and transporting her from the area to the hospital,” the sheriff’s office said in a statement.

The resort’s snowplow team was conducting an emergency avalanche control activity nearby, in the Skybarn area, when it happened, Vail officials said. The rest of the resort remained open.

Temperatures on Friday were below freezing, and a band of arctic cold rolled in overnight. It dipped to about 6 degrees Thursday night, and forecasters expect the frigid conditions to continue through Sunday.

“We will continue to monitor the avalanche warnings, and to continue snowmaking and other operations that aid in and protect the terrain,” said Jeff Hanle, Vail’s vice president of marketing and communications.
