Backcountry enthusiasts can win prizes for submitting avalanche observations to the Colorado Avalanche Information Center. The Friends of the Colorado Avalanche Information Center has launched an “observation challenge,” according to a news release from the nonprofit. The challenge encourages backcountry users to submit avalanche, snowpack and weather observations to the Colorado Avalanche Information Center, a state program. Colorado Avalanche Information Center forecasters publish daily avalanche reports that cover approximately 28,000 square miles from November through May, the release states. Backcountry travelers can submit observations related to avalanche activity, cracking or collapsing of the snowpack, snowpack structure and conditions, snowfall, skiing and riding conditions at Avalanche.State.co.us/observations/observation-report .
