1962 Map of Mt Mc Guire

About this map

Mt McGuire anchors this high-elevation survey of the Salmon River Mountains in the early 1960s. The landscape is defined by its dense concentration of alpine lakes and dramatic ridgelines within the Salmon National Forest. Notable geological formations like Fishfin Ridge and Gant Ridge segment the terrain, while water bodies such as Ship Island Lake, Harbor Lake, and Glacier Lake are connected by seasonal drainages like Ship Island Creek and Waterfall Creek. The map documents a primitive network of trails providing access to remote peaks including Beehive and Dome Mtn. This record is particularly useful for understanding the hydrologic patterns and named natural landmarks that predate later wilderness designations in the Lemhi County backcountry.
