This large GMU is dissected by the Wenas Valley as it meanders its way to the Yakima River at Selah. A large majority of the public land in this unit is Wenatchee National Forest, state land, and Wenas Wildlife Areas. The majority of private land is located along the major travel corridors, and Wenas, Lower Naches, and Selah Valleys. A bulk of the boundary edges follow waterways, including Umtanum Creek in the north, Naches River in the west, and Yakima River in the east. Cleman Mountain runs parallel between the Naches River and Wenas Creek. The northeastern face offers the darkest, old growth forest, however, this gives way to open rangeland in approximately two miles or so. The most rugged portion of the unit is the Oak Creek Wildlife Area, and is the best place to get away from roads. East of Wenas Valley is wide open, rolling scrubland comprised of sagebrush and grasslands, except for the various creeks offering enough water for buckbrush and other forbs.

There has been talk of wolves in this GMU. Hunters willing to hike will have a better opportunity at finding solitary, secluded honeyholes.
