1956 Map of May

USGS Topo · Published 1959

About this map

The Pahsimeroi Valley serves as the central focal point of this mid-century survey, framed by the towering heights of the Lemhi Range and the Lost River Mountains. The small settlement of May is situated near the valley floor, featuring a local Cemetery and a dedicated Landing Strip, indicating the reliance on light aircraft for connectivity in this high-altitude ranching region. The Pahsimeroi River meanders northwest through the valley toward the Salmon R, fed by numerous alpine tributaries like Falls Creek and Morse Creek. This landscape is largely defined by the intersection of the Salmon National Forest and Challis National Forest, where steep drainages such as Black Canyon and Dry Gulch descend from peaks like May Mtn and Long Mtn. The map documents a period when the sparse settlement at Ennis and the surrounding drainages remained essential nodes in the remote interior of Lemhi and Custer counties.
