About this map

Washakie Wilderness and the Shoshone National Forest dominate this high-elevation landscape within the Wyoming mountains. This 1991 revision, based on 1969 aerial photography, highlights a topography defined by steep ridges and dramatic drainage basins, specifically where the Wapiti Ranger District meets the Greybull Ranger District. The terrain is anchored by massive landmarks such as Needle Mountain and Crater Mountain, with significant watercourses like Needle Creek and Boulder Basin Creek carving through the granite and forest.

The lack of roads reflects the protected status of the wilderness, with the Boulder Basin Trail serving as one of the few established routes through the Boulder Ridge area. This map is a primary resource for tracing the high-country boundaries of the national forest and the headwaters of the North Fork Anderson Creek and South Fork Anderson Creek, showing the drainage patterns before modern digital elevation modeling became standard.
