MAMMOTH, CALIFORNIA — Authorities have identified the skier who died following a fatal fall on a notoriously dangerous slope at Mammoth Mountain.

According to the Mono County Sheriff’s Office, the victim was Robert Carroll, 40, of California. Carroll died last week while skiing at the resort. He lost control while attempting to descend Dropout Chute 2 — a trail infamous for being one of the steepest and most hazardous ski runs in California.

A harrowing eyewitness account of the accident was later posted on Reddit, describing Carroll’s death as “the worst thing” the witness had ever seen on the mountain.

According to the post, Carroll appeared to lose one of his skis while navigating a series of uneven moguls, possibly about 50 feet from the edge of a cliff. It was unclear whether he was wearing a helmet. He reportedly slid headfirst down the slope, striking his head on a rock.

The account further stated that Carroll, already unconscious, continued sliding roughly 150 yards down the trail, leaving a trail of blood behind him. A fellow skier was seen screaming and desperately chasing after him, attempting to jump on top of Carroll to stop his slide.

Information from Carroll’s social media indicates that he was originally from Vancouver, Washington, and later moved to Oakland, California. He was an avid rock climber and adventurer, with a passion for travel, including trips to Asia.

Carroll’s death marks the fourth fatality at Mammoth Mountain this winter season. In December, a snowboarder died at Climax Bowl. In January, one skier was killed in an avalanche at Cornice Bowl, while another died after losing control on Devil’s Slide later that same month.

Mammoth Mountain receives an average of approximately 400 inches of snowfall annually, and its snow season can sometimes extend as late as July.
