2013 Map of Little Trinity Lake

About this map

Boise National Forest dominates this high-elevation landscape within the Trinity Mountains, where a complex network of river forks and alpine lakes defines the geography. The map captures a concentrated recreation area centered around Little Trinity Lake and Big Trinity Lake, featuring the Little Trinity Lake Campground and the Little Roaring River Lake Campground. These sites serve as gateways to the surrounding wilderness, including the headwaters of the Roaring River, which splits into several distinct branches such as the Middle Fork Roaring River and E Fork Roaring River. Infrastructure in this part of Elmore County is limited to vital forest access routes like Trinity Ridge Rd and Trinity Mountain Rd, which navigate the steep terrain between peaks like Sheep Mtn and the various gulches. The drainage patterns are intricate, with several creeks like Whiskey Jack Cr and Rainbow Cr feeding into the larger river systems that carve through the mountain range.
