About this map

Washam is the primary point of settlement in this southern Sweetwater County landscape, situated where the high desert terrain meets the water system of the Henrys Fork. The map documents a complex network of water management essential for ranching and agriculture in this arid region, featuring a series of catchments including Briggs Reservoir, Silk Reservoir, Middle Reservoir, and Neff Reservoir.

Natural drainage patterns are defined by the winding course of the Henrys Fork, which is fed by smaller tributaries such as Little Dry Cr and Lane Meadow Cr. Topographical features like Logan Hollow and Big Hollow flank the central Antelope Wash, while reliable water sources like Antelope Spring and Richardson Spring provided critical anchors for local movement and land use. The presence of Washam Rd and Briggs Ln suggests the established routes connecting these isolated homesteads and grazing lands.
