The Bitterroot Divide forms a high-altitude spine through this late-twentieth-century survey, marking the jurisdictional boundaries of the Lolo National Forest and Bitterroot National Forest. This section of the Sapphire Mountains is characterized by its network of saddles and ridges, including Holloman Saddle and Cooney Ridge, which dictate the flow of numerous drainages like Plant Creek and Eightmile Creek. The landscape transitions into protected territory within the Welcome Creek Wilderness in the southeast, where the South Fork Welcome Creek flows. Evidence of local industrial activity is noted at the Gravel Pit near the northern boundary, while natural water sources like Lost Drink Spring provide critical landmarks for those navigating the higher elevations near Elk Mountain.
