It seems as if every river in the mountains is fed by at least one Hellroaring Creek. None is more deserving of the name, however, than the torrent of water that drains the alpine basins of Montana's Beartooth Range. It's a land of rocky crags, soaring cliffs, and random ridges of pine, where mountain goats are king and wise hunters tread carefully. On a September morning in 2001, Ross Winfrey of Livingston, Montana, and his uncle were hunting this drainage when they spotted some goats from the crest of a ridge. White against the cliffs, the goats were up another precipitous mountainside, across a valley. Winfrey and his uncle decided to go after them.
