1956 Map of May

USGS Topo · Published 1975

About this map

The Pahsimeroi Valley serves as a central corridor for high-altitude ranching and settlement in the mid-1950s, bounded by the towering peaks of the Challis National Forest and Salmon National Forest. The settlement of May sits as a primary hub within the valley, supported by a nearby Landing Strip and a Cemetery, indicating the established nature of this remote mountain community. To the north, the terrain transitions into the steep drainages of the Salmon River, while the southern reaches are dominated by the Lost River Mountains. The map reveals a landscape defined by water rights and access, with numerous named creeks such as Patterson Creek and Morgan Creek feeding the Pahsimeroi River. The presence of bench marks like BM 5022 and BM 5321 near Patterson underscores the detailed survey work required to manage this complex topography of gulches and peaks like May Mtn.
