About this map

Lewis & Clark National Forest and Flathead National Forest converge in this high-altitude landscape within the Lewis and Clark Range. The topography is defined by significant elevations such as Patrol Mtn and Sugarloaf Mtn, with Observation Pass providing a named transit point through the ridgelines. The drainage system is anchored by the S Fork Sun River, which collects numerous tributaries including Ellis Cr and Hoadley Cr.

Remote infrastructure is limited but notable, specifically the Benchmark Airport located in the northeast near Wood Canyon. The map reveals a wild landscape where drainage basins like Grizzly Basin and Honeymoon Basin are carved between steep features like the Wood Creek Hogback. This 2017 survey reflects the enduring wilderness character of this montane region, where water bodies like Benchmark Cr and Sugarloaf Cr follow narrow canyon floors.
