Three snowboarders were caught in an avalanche in Maroon Bowl on Monday then two of them had to fight off multiple attacks from a moose after self-rescuing from the slide.

One of the riders suffered a broken rib and a strained back after getting pinned against a tree and covered with snow in Maroon Bowl, according to Blase Reardon, forecaster for the Aspen Zone of the Colorado Avalanche Information Center. Reardon talked to the victim by phone and posted a report on the CAIC website Tuesday.

Reardon was in the field Wednesday and couldn’t be reached for additional comment about the incident or the identity of the riders. Maroon Bowl is just outside the boundary of Aspen Highlands ski area. It shares the same ridge as Highland Bowl.

The riders were on a northerly slope of Maroon Bowl at an elevation of about 10,650 feet, according to the report. They were filming higher in the bowl earlier in the day. Right before the slide all three entered a slope. The victim, whose name wasn’t available, told Reardon they “got lazy” and didn’t follow their usual protocol of entering the slope one at a time.

“About 300 vertical feet below the ridge and just below a big tree that was near a convexity, the slope avalanched,” Reardon wrote in his report. “It broke above them and all three were caught and carried several hundred feet down the slope.”
