About this map

The White River drainage system dominates this section of the Flathead National Forest, carving a path through a series of high ridges and mountain passes. The landscape is defined by its dramatic geological formations, most notably the Chinese Wall, a prominent escarpment that runs through the central portion of the sheet. This area remains largely defined by its natural water features and vertical relief, with significant peaks like Amphitheatre Mountain and Turtlehead Mountain providing the primary landmarks for navigation.

Water flows from high alpine sources like My Lake and Diamond Lake, feeding into numerous tributaries including Cliff Creek and Pagoda Creek. The presence of named passes and flats, such as Larch Hill Pass and Brushy Park, indicates the established routes used to traverse this complex terrain. This survey provides a precise look at the hydrology and topography of the Bob Marshall Wilderness area at the start of the 2010s, tracing the relationship between the river valley and the surrounding summits like Gladiator Mountain and Sphinx Peak.
