About this map

Trinity Mtn Lookout stands as the central landmark of this high-elevation backcountry, part of the Boise National Forest during the mid-1960s. The area is defined by a dense concentration of subalpine lakes, including Big Trinity Lake, Roaring River Lake, and the colorful series of Big Rainbow Lake, Middle Rainbow Lake, and Little Rainbow Lake.

A complex network of primitive transportation routes, such as the Windy Trail and various Pack Trail segments, suggests a landscape managed for fire lookout access and seasonal recreation. The hydrology is intricate, with numerous drainages like Fall Creek and East Fork Smith Creek carving through the terrain from peaks like Red Mtn. This survey captures the wilderness character of Elmore County before significant modern changes, preserving the locations of remote mountain springs and isolated water bodies like Hideaway Lake and Fiddle Lake.
