1988 Map of Aldrich Basin

About this map

Aldrich Basin serves as the central focal point of this high-altitude landscape, where the rugged topography of Carter Mountain defines the drainage patterns of the upper Bighorn Basin area. The map illustrates a transitional environment governed by the Shoshone National Forest, with a significant portion of the southern terrain protected under the Washakie Wilderness designation. A complex network of watercourses, including Aldrich Creek, Little Boulder Creek, and the West Fork Rock Creek, carves through the steep slopes. The presence of a clear Wilderness Boundary and isolated features like Piney Pass underscores the undeveloped and remote character of this region during the late 20th century. For the researcher, the map preserves the exact alignment of seasonal trails and minor tributaries such as Warhouse Creek and Betty Creek before modern environmental shifts or administrative changes.
