This hunt area has large mountains that rise in elevation very quickly from the creek bottoms. These mountains are very steep and covered with thick, dark conifer timber that transforms into grass-covered mountain tops at the treeline. Large bucks are known to frequent this unit, with many record book bucks found every year.

The elevation in this area can change quickly and creates the steep mountains found here. Many rocky cliff areas are found in higher elevations where large mule deer bucks have bedding grounds. Thick, forested hills with large amounts of downfall can make some trails difficult to hike. Most lower elevations have a creek or stream running through all year long.

The bottoms of the canyon are covered in thick willow bushes, aspen trees along the creeks and streams with beaver dams that create grass flats. Most of the mountain sides in this area are covered with conifer trees. Wildflowers and short high mountain grasses cover the rock fields above the treeline.

The majority of this unit is in the National Forest and many locations have marked Forest Service roads to guide hunters deep into the woods. Maintained hiking trails provides hunters with access to the backwoods where large deer roam the mountain sides.

Hunters that go into the backcountry can camp remotely with no fees required. Hunters can also stay in lodging found east of the unit in Jackson Hole or to the west in Palisades Idaho.
