1989 Map of Mc Cormick Peak

About this map

The Reservation Divide serves as the prominent physical and administrative backbone of this mountain landscape, marking the high-altitude boundary between the Flathead Indian Reservation to the north and the Lolo National Forest to the south. This boundary also aligns with the county line between Sanders and Missoula Counties, tracing a series of high points including Mc Cormick Peak, Blackrock Peak, and Josephine Peak. The map reveals a history of resource extraction tucked into the steep drainages, specifically within Favorite Mine Gulch, where the Favorite Mine and associated Tailings indicate localized mining activity. The drainage patterns are well-defined, with the headwaters of Revais Creek and its various forks flowing north, while Mc Cormick Creek and Butler Creek drain the southern slopes. Several Pack Trails provide the primary access through this remote terrain, connecting the high basins like Blacktail Basin to the valley bottoms.
