This small unit bordering Oregon is split approximately 60/40 between private and public land. The 4-0 Ranch Wildlife Area is located at the center of the unit, bordering the south side of Umatilla National Forest. Grouse Flats Unit and several sections of BLM on the southside breaks of the Grande Ronde River also provide public hunting opportunities. The 4-0 Ranch Unit within manages deer and elk tags by special draw permit only access. The National Forest is the largest chunk of public property and provides good backpack or pack animal hunting with very little in the way of interior roads.

A small but growing sheep population is doing very well in this unit. Anyone with a tag will be in for a great hunt.
