The Lochsa River carves a path through the northern reaches of this Idaho County terrain, where the U.S. Forest Service infrastructure supports backcountry access. Public recreation sites like the Major Fenn Picnic Area and Knife Edge Campground sit adjacent to the river’s course, marking the primary corridor for travelers. The Split Creek Bridge provides a critical crossing point near Black Canyon, where the water narrows between steep slopes.
