A 22-year-old Tempe man his dead after hitting a tree Monday at Arizona Snowbowl in Flagstaff, authorities said.

The skier struck the tree before 11 a.m. Jan. 22 after which Coconino County Sheriff’s Office officials said they received a report of a seriously injured person being treated at the resort.

Ski patrol personnel were at the scene, and emergency medical services were dispatched, officials said.

Deputies responded to the area and found that the patient was in a first aid station, according to CCSO. Paramedics from Guardian Medical Transport also were at the location.

“The patient apparently succumbed to injuries and was declared deceased at the location,” a CCSO Facebook post stated.

“According to information collected by deputies, the skier was initially skiing on ‘Upper Ridge’ run, which is labeled with a ‘black diamond’ or ‘most difficult’ terrain rating. The skier is believed to have skied just outside a boundary line and struck a tree.”

The incident remains under investigation.

A CCSO spokesman said names of accident victims are not released by the office.
