2023 Map of Trinity Mountain

USGS Topo · Published 2023

About this map

Trinity Mtn and the adjacent Trinity Lookout command the high ground of the Boise National Forest in this 2023 survey. This portion of the Boise river system is defined by a dense concentration of subalpine lakes, including the notable Big Trinity Lake, Big Roaring River Lake, and Twin Sisters Lakes. The drainage patterns are intricately mapped, showing the headwaters of Trinity Creek and Fall Creek as they descend from Trinity Ridge. A network of established paths like the Rainbow Basin Trl and Bear Hole Trl connect these water bodies, while the presence of the Tally-Baker route and various forest spurs indicates the modern management and recreational use of this Elmore County high country. Significant peaks such as Lava Mountain and Red Mtn frame the lake basins, illustrating the complex hydrology of the western Idaho mountains.
