2021 Map of Prehistoric Rim

About this map

Prehistoric Rim and Skull Creek Rim define the high desert topography of this Sweetwater County landscape. The drainage patterns are clearly marked by the winding paths of Skull Cr and Sand Cr, which gather the occasional runoff from these arid elevations. In the central portion of the quadrangle, Haystack Wash carves a distinct channel through the terrain, while East Fork Point provides a prominent landmark overlooking the creek beds below. This 2021 survey offers a modern look at the public land survey system divisions across townships T13N through T15N, showing the precise grid that organizes this open rangeland. The absence of named settlements or heavy infrastructure emphasizes the remote character of this high-altitude Wyoming basin, where the primary features are geological and hydrological rather than man-made.
