2011 Map of Trinity Mountain

About this map

Trinity Mountain serves as the focal point for this high-altitude landscape in the Boise National Forest area, where a dense network of subalpine lakes and cold-water drainages defines the geography. At the time of this 2011 survey, the region supported recreational infrastructure centered around Big Trinity Lake Campground, Big Roaring River Lake Campground, and Cold Spring Campground. The map reveals a complex hydrologic system where numerous named water bodies, including Heart Lake, Fiddle Lake, and Big Lookout Lake, feed into descending drainages like Rainbow Creek and Bear Hole Creek. Access is primarily facilitated by the winding Trinity Mountain Rd, which navigates the steep elevation changes between peaks like Red Mountain and the various creek basins such as Dry Buck Creek and Anderson Creek.
