1989 Map of Dennison Cap

About this map

Siberia Ridge dominates the northern landscape of this Sweetwater County quadrangle, a high-desert expanse characterized by remote sheep camps and intermittent water sources. Based on field work from the late 1950s and mid-1980s, the map reveals a land utilized for grazing and energy extraction. Seasonal watering spots like Twelvemile Hole and Black Lake provide critical landmarks in a region largely defined by its topography, such as the prominent Dennison Cap. The infrastructure consists primarily of unimproved paths and industrial corridors, including a pipeline and the Luman Ranch Road. Remote outposts such as Buzzard Sheep Camp and Circle Bar Sheep Camp suggest the enduring importance of livestock ranching in this isolated portion of Wyoming, while scattered Gas Wells reflect the area's development for natural resources during the latter half of the 20th century.
