1963 Map of Colona

Water management and transportation dominate the terrain, evidenced by the West Canal and South Canal that cut through the valleys. The map documents an extensive network of Jeep Trails and the Government Springs Road, which navigate the complex drainage systems of Broman Canyon and Horsefly Creek. This area on the Montrose and Ouray county line illustrates the transition from river-bottom ranching and rail transit to the high, arid mesa lands of western Colorado.
