1980 Map of Hinman Reservoir

About this map

Muddy Creek flows through this high-altitude drainage basin north of the Colorado River during the late 1970s. The landscape is defined by its complex water management and ranching infrastructure, evidenced by the Mc Mahon Ditch and a network of named drainages like Pass Creek, Slough Creek, and Red Dirt Creek. The Hinman Reservoir serves as a central hydrological feature, while the presence of a lone Cem and scattered Drift Holes or Drill Holes suggest a history of local burial sites and resource exploration. Fences, marked by fine dashed lines, crisscross the terrain near Wolford Mountain, revealing the managed nature of this open range. This survey captures a moment when traditional land use, from grazing to gravel extraction at the various Gravel Pits, remained the primary activity in this portion of Grand County.
