1964 Map of Little Trinity Lake

About this map

Boise National Forest encompasses this high-elevation landscape in Elmore County, defined by a complex drainage network that feeds the Roaring River and Trinity Creek. The mid-1960s terrain is marked by an intricate system of pack trails and forest service infrastructure, notably the Trinity Lakes Guard Station situated near the southern cluster of alpine lakes. This area serves as a focal point for backcountry management and recreation, featuring the Trinity Lake Campground and Big Trinity Campground near the water's edge. The hydrography of the region is particularly dense, with various forks and tributaries such as the Middle Fork and East Fork carving through the slopes below Sheep Mountain. A legacy of early mountain travel is preserved in the numerous pack trails that navigate the ridges between drainages like Deadman Creek and Whiskey Jack Creek, indicating a landscape accessed primarily by horse and foot during this era.
