About this map

The Sawtooth Range and the Castle Reef formation dominate this mountain landscape along the eastern edge of the Lewis and Clark National Forest. Revised in the mid-1990s, this survey documents the rugged drainage systems where the North Fork Deep Creek and South Fork Deep Creek meet. The map reveals the intricate network of gulches and creeks that define the transition from the high peaks down toward the plains, notably including Green Timber Gulch and Hannan Gulch.

Settlement patterns are sparse, characterized by isolated holdings like Kellogg Ranch and Davy High Ranch. At the southern edge of the sheet, the Sun River and the Pishkun Canal indicate the vital role of water management in this Montana backcountry. For the researcher, the map preserves specific local place names like Wagner Basin and provides a detailed look at the Blacktail NRT 122 trail through the high country.
