The murky waters of the Yellowstone serve as the backdrop for the adventurous survival of the brown trout, Oncorhynchus clarki. Every year, these trout swim upstream to spawn, but their journey is hindered by a thousand dangers. Attacked from the air, on land, and in the water, these defenseless prey seek to return to their birthplace.
