The Lewis and Clark National Historic Trail follows a high, winding route through this mountain landscape, mirroring the historic passage of explorers across the Beaver Ridge divide. This 1994 revision shows the area as a preserved wilderness and forest interior, where human presence is largely limited to backcountry stations like the Roundtop Lookout and primitive stopping points such as Glade Creek Camp and 21 Mile Camp.
