1980 Map of Hinman Reservoir

About this map

Muddy Creek defines the drainage of this high-elevation Grand County landscape, where the seasonal flow and irrigation needs of the late 1970s are evident in features like the Mc Mahon Ditch. The presence of the Hinman Reservoir and various Drill Holes suggests a terrain utilized for both water management and resource exploration. Settlement indicators are sparse but specific, including a lone Cem and multiple Gravel Pits that suggest local infrastructure maintenance. To the south, the topography rises toward Wolford Mountain, with numerous tributaries such as Pass Creek, Red Dirt Creek, and Antelope Creek carving through the valleys. The map provides a detailed record of the water-reliant economy of the era, from the Alkali Slough to the many named springs and gulches that supported ranching or mining activities.
