Sitting in the eastern shadow of Mount Rainer, the Bumping River unit is a great place to look for mountain goats. This unit is made up of multiple ridgebacks leading up to Mount Aix, a dominant terrain feature in this unit. As you climb out of the trees, these ridgelines hold numerous ideal habitats for goats, from small craggy outcroppings to large snowfields and sheer rock faces. The level of physical effort to hunt this unit is often considered moderate but plan on a multiple mile hike gaining several thousand feet in elevation before you reach good goat habitat. Once you have gained some elevation, the hike is not extremely strenuous from there. Although day hikes are possible, it is probably best to plan on spike camping for a few days in the unit. Keep in mind that there is little water available in this unit, and plan accordingly.

Although there are few reports of goats on Timberwolf Mountain, there is a road to the top of this area that will allow you to get a great vantage over most of the more popular goat peaks in the area, including Mount Aix, Nelson Butte and more. A trip up to this lookout at the beginning of your hunt should be very helpful in deciding where to go, as it is very easy to look over many of the peaks in the area with good optics.
