This area located south of Challis has thousands of square miles of moose habitat between some of the highest terrain in the state.

Moose hunters in this unit have had success in tagging mature bulls. Bulls typically range from 35-43”

The northern tip of this unit has terrain varying from flat desert lowlands to some of the highest, rockiest and most rugged mountains in the state. Some high points exceed 11,000 feet in elevation, including Castle Peak, Easley Peak, Galena Peak, Glassford Peak, Silver Peak and Ryan Peak. Antelope Flats, farm fields, river bottoms and barren foothills in the northern and eastern parts of the area can be found here. Between extremes are countless ridges, foothills, draws and mountains that are mostly between 6,000 and 8,000 feet above sea level.

The western and northern parts of the unit are covered with sagebrush and wild grasses. Willows and cottonwoods line the Salmon River while fields planted in grass hay, alfalfa and other crops line Warm Springs Creek. Aspens grow in some foothill draws. Mahoganies, bitterbrush, serviceberries, river birch and alders grow in places. Pines and firs grow on north and east-facing slopes above about 7,000 feet. Above 8,000 feet and below timberline grow spruces, pines and subalpine firs.

Road access starts from U.S. Highway 93 and Idaho Route 75. Many interior roads intersect the main routes including Bradbury Flat Road, Spar Canyon Road and East Fork Road. These roads lead to other public roads which lead toward high mountains like Boulder Creek, Herd Creek and Jim Livingston Mine roads.

Hunters can camp along dirt roads. Several primitive campgrounds are found along Idaho Route 75 with a couple of private facilities like Old Sawmill Station in Clayton and nearby May Family Ranch. The BLM has a primitive Herd Lake campsite. Another primitive campsite is located on the East Fork Road just north of the mouth of Germania Creek. Lodging is available in Challis.
