2013 Map of Trinity Mountain

About this map

Trinity Mountain stands as a central landmark in this high-elevation reach of the Boise National Forest. The landscape is defined by a dense concentration of subalpine lakes and the headwaters of numerous creeks, including Rainbow Creek and the West Fork Fall Creek. A network of forest infrastructure supports seasonal access, with established sites like the Big Trinity Lake Campground, Big Roaring River Lake Campground, and Cold Spring Campground clustered around the peaks. This 2013 survey illustrates the rugged drainage patterns of the Trinity Mountains, where names like Potter Lake, Smith Creek Lake, and the Twin Sisters Lakes suggest a history of local land-marking in a wilderness area shaped by glacial activity and steep timbered slopes.
