2020 Map of Patterson

About this map

Patterson is situated at the foot of the Lemhi Range, where the steep mountain slopes meet the agricultural lands of the Pahsimeroi Valley. This 2020 survey illustrates the transition from the protected wilderness of the Challis National Forest to the settled valley floor, defined by a network of local roads such as Farm To Market Rd and Wallis Ln. The drainage patterns are a central feature, with Patterson-Morse Creek and the E Fork Patterson Cr flowing from the high country toward the valley. The presence of Miller Rd and Patterson Creek Rd indicates a landscape shaped by rural ranching and access to the canyon waterways. This map provides a modern record of land use in a region where remote mountain terrain and valley agriculture coexist.
