Perhaps no one loves trout as much as James Prosek, who by age 20 journeyed thousands of miles and through 49 states to depict in watercolors all 70 subspecies of North American wild trout at least four times for this definitive volume on the subject. He details the diversity and brilliant range of colors in the species with his paintings, which are accompanied by written snippets, including angling anecdotes, historical sketches and personal reminiscences. At the devastating rate that trout are being lost to hybridization, displacement and extinction, we should be thankful that Prosek's obsession has led to this beautiful document of the species now, before it is too late.
