Clearwater National Forest dominates this landscape, where the high ridges of the Bitterroot range divide complex drainage systems. The survey area is defined by massive topographical features like French Mountain and Dan Lee Ridge, with the namesake Hemlock Butte rising in the northeast corner at the boundary of Clearwater Co and Idaho Co. The map reveals a dense network of forest service roads, such as French Mountain Rd and Nat For Dev Rd 103, providing access to specialized terrain features including Lost Hat Saddle and Winter Draw. Waterways like Musselshell Cr and Orofino Cr cut through deep gulches, illustrating the classic drainage patterns of north-central Idaho’s timbered highlands. This sheet is particularly useful for understanding the modern access routes into high-elevation sites like Chamook Ridge and Austin Ridge.
