A Utah snowmobiler accidentally triggered an avalanche that buried his brother, whom he was able to save after spotting his fingers sticking out of the snow. The brothers and their father were riding snowmobiles across the slopes in the Franklin Basin area of the Utah backcountry near the Idaho border, according to the Utah Avalanche Center.

A man rescued his brother from a “large avalanche” he triggered while the pair were snowmobiling in Utah on Wednesday, authorities said.
