A 53-year-old skier from Pennsylvania died after an accident at Steamboat Resort Saturday, officials said.

Frank Maimone, of Philadelphia, was found unresponsive near an area at the bottom of Shadows Glades around 2:30 p.m.

“Steamboat ski patrol arrived on the scene and administered advanced life support,” said Loryn Duke, Steamboat spokeswoman.

Maimone was taken to UCHealth Yampa Valley Medical Center, where he died, she said.

Routt County coroner Robert Ryg said he will do an autopsy on Monday to determine how Maimone died, but said the man suffered trauma in some sort of accident on the mountain.

“It was an accident,” he said. “We’re not exactly sure what happened, if he was injured in the accident or went into a tree well.”

The man’s death is the first fatality this season at Steamboat Resort.
