1986 Map of The Pinnacles

About this map

The Pinnacles dominate this high-desert landscape in southwestern Wyoming, where jagged terrain features drop toward the winding depression of Alkali Draw. Surveyed in the early 1980s, the map reveals a remote and arid expanse characterized by deep basins and seasonal drainages. The Alkali Basin occupies the eastern portion of the sheet, while Bush Creek carves a narrow path in the north. This 1986 provisional edition captures the topography of Sweetwater County as it existed prior to extensive modern development, noting only essential landmarks such as a lone Well near the basin. The scarcity of named human settlements emphasizes the isolation of this corner of the state, where the natural geology remains the primary focus for researchers and explorers.
