1957 Map of Grizzly Ridge

About this map

Black Canyon of the Gunnison National Monument dominates this mid-century survey, showcasing the sheer drop-offs and complex geology of the Gunnison River gorge. The map details the infrastructure required to navigate this vertical landscape, from the North Rim Ranger Sta and South Rim Ranger Sta to the critical water management of the Vernal Ditch. At the bottom of the canyon, the East Portal marks a significant point of human intervention in the river's flow. On the surrounding plateaus, the landscape transitions to the agricultural and grazing lands of Fruitland Mesa and Vernal Mesa. Significant local landmarks like Orchard Corner and the Bostwick Park Road indicate the established rural road network during the late 1950s. The topography is dotted with family-named features and local geographic identifiers, including Jones Summit and Poison Spring Hill, which define the high ground between the deep gulches.
