About this map

Sheldon National Wildlife Refuge dominates the western half of this 1990 survey, protecting a high-altitude desert landscape where the slopes of Big Mountain descend into the rugged drainage of Idaho Canyon and Little Idaho Canyon. The map captures the remote ranching infrastructure of Humboldt County, centered on the Knott Creek Ranch and a network of water management features essential for survival in the Great Basin.

Strategic water sources like West Spring and Indian Spring feed into West Creek and Craine Creek, eventually reaching the broad Alkali Flat to the northeast. To the south, the terrain rises into the northern reaches of the Black Rock Range. This provisional edition provides a meticulous look at the land use of the era, recording scattered Stock Ponds, a Borrow Pit, and irrigation Ditch segments that illustrate the intersection of conservation and cattle ranching.
