2020 Map of Mount McGuire

About this map

Mt McGuire and the dramatic topography of the Bighorn Crags dominate this high-elevation portion of the Salmon National Forest in Lemhi County. The landscape is defined by its complex network of alpine basins and granite ridges, containing dozens of named lakes including Ship Island Lake, Gooseneck Lake, and Roaring Cr Lakes. The survey illustrates the glacial carving of the region, where features like Fishfin Ridge and Fishing Ridge separate drainage basins. Notable landmarks like Cathedral Rock and Dome Mtn serve as primary navigational points in this wilderness area. The map also records numerous seasonal waterways such as Garden Cr and Waterfall Cr, alongside unique features like Ship Island and the humorously named Puddin Mountain.
