It is situated in the Great Bear Wilderness, on land managed by Flathead National Forest.

Precipitation runoff from the mountain drains north to the Middle Fork Flathead River via Roaring, Argosy, and Dolly Varden creeks.

Topographic relief is significant as the summit rises 2,350 feet (720 meters) above Argosy Creek in one mile.

Access to this remote peak is from the nearby Shafer Ranger Station at the Schafer landing strip which was grandfathered with the wilderness designation.

Argosy Mountain is composed of sedimentary rock laid down during the Precambrian to Jurassic periods.
