May Mtn and the high ridges of the Lemhi Range dominate this portion of Idaho's high country, marking the boundary between the Salmon National Forest and Challis National Forest. The landscape is defined by a dense network of drainage systems, including Hayden Creek flowing toward the north and Morgan Cr to the south. Historically significant for its rugged geography, the area shows very little human infrastructure beyond Morse Creek Rd, which follows the contours of the Morse Creek drainage. Notable peaks like Long Mtn provide essential landmarks for navigation within these national forest lands. Local history and genealogy researchers may find the specific naming of gulches and creeks, such as Spring Gulch and Bray Cr, useful for pinpointing early ranching or mining claims that often relied on these seasonal water sources for survival and commerce.
