About this map

Pahsimeroi Valley floor meets the steep, eastern front of the Lemhi Range here, creating a landscape defined by sharp elevation shifts and alluvial drainage. The small settlement of Patterson is situated at the canyon mouth where Patterson-Morse Creek exits the mountains and enters the flats. This interface is marked by a network of local roads such as Farm To Market Rd and Pahsimeroi Rd, which suggest a history of agricultural and transit-based land use at the valley's edge.

Public lands dominate the higher elevations, split between the Salmon National Forest to the north and the Challis National Forest to the south. Numerous drainage features like Falls Cr, Mahogany Cr, and the E Fork Patterson Creek carve into the mountain mass, while family-named landmarks like Miller Rd and Wallis Ln offer clues to the early ranching and homesteading families who settled this part of Lemhi County.
