Siskiyou National Forest land defines this portion of the Klamath Mountains, where the drainage of the Chetco River meets steep, high-elevation summits. The terrain is characterized by prominent peaks like Big Craggies, Green Craggie, and Mislatnah Peak, which tower over a network of tributary waters including Collier Cr, Mislatnah Cr, and Tincup Cr. In a landscape dominated by sharp vertical relief, small pockets of level ground are identified at High Prairie and Lately Prairie. Human activity is primarily represented by Forest Service access routes, such as Nat For Dev Rd 1376 and Nat For Dev Rd 060, providing passage to points like Humboldt Spring. The map documents the complex boundary between Josephine and Curry Counties, following the ridgelines that separate these watersheds.
