About this map

Boise National Forest provides the setting for this high-altitude survey of the Trinity Lakes region, dominated by the drainage systems of the Roaring River and Trinity Creek. The map centers on a concentration of mountain lakes and seasonal outposts, including the Trinity Lakes Guard Station and established campgrounds. The hydrologic network is intricately detailed, showing the headwaters of the Middle Fork Roaring River and the complex of streams such as Whiskey Jack Creek and Deadman Creek.

A network of pack trails and unimproved roads represents the primary means of movement through the terrain, connecting the high points like Sheep Mountain to the various basins. Notable water bodies such as Big Trinity Lake, Little Trinity Lake, and the remote Twin Sisters Lakes are depicted alongside specific landmarks like Roaring River Lake. The mapping of these trails and water sources reflects the mid-century infrastructure for forest management and recreation in the Elmore County wilderness.
