About this map

The high ridges of the Bitterroot Range define this landscape along the boundary of Flathead and Sanders County, where the Lolo National Forest meets the Flathead Indian Reservation. This 1990s revision of earlier 1960s topography highlights a network of forest roads and trails that traverse significant summits like Bassoo Peak, Pashua Peak, and Snowstorm Mountain. The drainage patterns show a series of creeks flowing from the high divides, including Big Rock Creek in the north and Chippy Creek to the west.

Water management in this high-altitude environment is evidenced by the Alder Creek Ditch in the southern section, which skirts the slopes below Thompson Peak. The presence of Snowstorm Azimuth near the northern peaks indicates the area's importance for surveying and lookout operations within the national forest. This sheet documents the intersection of federal forest management and tribal lands during the late twentieth century.
