This large GMU is located on the north bank of the Columbia River, between I-5 in the east and the Chehalis River to the west. Other than a large piece of state land in the southwestern portion, the unit is basically all private, dominated by large timber companies except along the major rivers and interstate. Here the private land is divided into small tracts of all sizes stuck together like a puzzle making land access and hunting a bit more difficult, but not impossible, for those willing to do just a bit of legwork early on. The timber companies typically offer public access, however, this access can easily close if fire danger is too high. In the southwestern tail along the Columbia River lies the Julia Butler Hansen Refuge for Columbia Whitetail deer. Boistfort Peak is the high ground at 3,087 ft and is located on Weyerhaeuser land. Steep to rolling mountains that have been heavily logged throughout the years create a patchwork of forests and a network of roads and trails that seem to go everywhere. Boistfort Prairie and the South Fork Chehalis River create a low-lying vertical strip of ground right down the center of the GMU giving easy access along Wildwood Road to the center of unit, however, it is all private land through here. Whether you choose to hunt public state land, large timber company ground, or gain access on smaller private land, there are hunting opportunities for those willing to do a bit of homework. There are significant numbers of deer throughout the area, but the unit is also heavily hunted so it is best to find areas not often traveled, which is difficult.

Timber companies typically offer some access however, it does not seem to be consistent from year to year.
