About this map

The Lemhi Range dominates this corner of Idaho, where the high-altitude landscape is split between the Targhee National Forest and the Challis National Forest. This modern survey details a complex system of drainage and relief, with prominent peaks like Bald Mtn and Mahogany Butte rising above a series of deep gulches and canyons. The Birch Creek Valley provides a lower-elevation corridor on the eastern side of the quadrangle, where Birch Creek flows near W Foothill Rd.

Access into the interior is marked by specialized routes such as Eightmile Canyon Rd and Windfall Canyon Rd, which navigate the steep transitions between the valley floor and the mountains. From Bald Mountain Spring in the north to the depths of Big Dry Canyon in the south, the map illustrates the hydrography and terrain of the Clark County and Butte County borderlands, including named features like Surrett Canyon and Post Canyon.
