This is the story of Michigan's 150 mile copper range, from the preposterous, premature, greedy boom days of the 1840's down to the present. Interwoven is the life in boom-camp towns, cold, hunger, moderate dissolution, and the personalities who played a part in fact and legend. Douglas Houghton, the Columbus: the fortune hunters who followed him but didn't know how to prospect; Sam Knapp, who hit a jackpot; Hulbert who was led to the richest lode by a herd of pigs, etc. The discovery of virgin copper, when pure copper was unheard of, the lesser motif of silver; peak days during the first war, to be followed by the depression, labor troubles, with no betterment today. Good indigenous material, for the early Holbrook market.
