Chinese Wall stands as the dominant geological landmark along the eastern edge of this 2017 survey, marking the dramatic divide where Lewis & Clark National Forest meets the Flathead National Forest. This high-altitude wilderness area is defined by its vertical relief and water systems, including the headwaters of the White River and the South Fork Flathead River. The map details a complex network of ridges and summits such as Gladiator Mtn, Tillson Peak, and Shale Peak, which form part of the larger Lewis and Clark Range. Significant hydrological features like Needle Falls and Francois Cr demonstrate the steep drainage patterns of the Flathead Alps. As a modern record, the map shows the preservation of these lands across three counties, including Flathead, Powell, and Lewis and Clark, through its depiction of the Continental Divide and its associated passes like White River Pass.
