Trap Mtn and Woodtick Mtn anchor this high-elevation landscape within the Lewis & Clark National Forest and Flathead National Forest. The map documents a complex drainage system where waters like Danaher Cr, Basin Cr, and Ayres Cr carve through deep alpine basins. The terrain is marked by prominent ridges and peaks, including Scarlet Mtn and Sentinel Mtn, which define the boundary between Powell and Lewis and Clark counties. A significant corridor for movement through the high country is preserved at Camp Creek Pass, located near the northern edge of the survey. The absence of developed roads emphasizes the area's character as a primitive backcountry environment, defined instead by geological features like Hoadley Reef and vast depressions such as Pearl Basin and Grizzly Basin.
