2021 Map of Old Iron Mountain

About this map

Eldorado National Forest encompasses this high-elevation landscape, where the Sierra Nevada's drainage patterns are defined by the N Fork Cosumnes River and the Steely Fork Cosumnes River. The map highlights a network of historic forest settlements including Bryants, Bonetti, and Griminger, which represent the scattered residential and logging hubs of the mid-20th century. The terrain is dominated by prominent landforms like Old Iron Mtn and Plummer Ridge, intersected by a complex system of forestry roads and recreational paths.
