About this map

The Lander Trail cuts a historic path through this high-elevation landscape within the Bridger National Forest, marking a critical corridor for westward expansion in the nineteenth century. Anchored by the prominent Mt Thompson and Thompson Pass, the terrain is defined by a series of significant uplifted features including Witherspoon Ridge, Absaroka Ridge, and Packsaddle Ridge. These heights separate deep drainages such as Snyder Basin and the Meridonal Valley.

Water sources are abundant across the slopes, from the headwaters of S Piney Creek in the north to S La Barge Cr and Little Fall Creek further south. The map provides a clear view of the complex hydrology of the region, including smaller features like Indian Spring and Nameless Cr. This document is an essential resource for tracing the physical geography and historical migration routes across the Lincoln and Sublette county line.
