About this map

Oro Mountain stands as a central peak in this high-altitude landscape within the Boise National Forest in late-twentieth-century Idaho. The map reveals a complex network of drainages and passes, most notably where the Middle Fork Payette River cuts through the southeastern corner. Higher elevations are marked by the North Fork Range, while the terrain is punctuated by landmarks such as Grouse Rock and high-mountain water bodies like Curtis Lake.

Evidence of early travel and transit through these mountains is found at Railroad Pass and Clear Creek Summit, providing a look at how this part of Valley County was traversed before modern improvements. The landscape shifts from the open expanses of Stony Meadow and Porcupine Flat to the steep ravines formed by Johnson Creek and Hargrave Creek. This survey captures the wilderness character of the region as it was documented in the 1980s.
