Salmon National Forest defines this high-elevation landscape in Lemhi County, where the Yellowjacket Mountains meet a series of prominent peaks and ridgelines. The topography is dominated by massive landforms such as Blackbird Mountain, Quartzite Mountain, and Red Rock Peak, creating a complex drainage network that feeds into Big Deer Creek and Musgrove Creek. Historically part of a region known for its remote mining and timber potential, the map reveals a system of forest roads and trails including the Blackbird Mtn Rd and Yellowjacket Rd that navigate the steep terrain between Remenclau Saddle and Porphyry Ridge. The presence of labels like Road 260 Con With ATV indicates the modern recreational use of these historical corridors through French Gulch and across the headwaters of Fourth of July Creek.
