The 15,720 acre Tatoosh Wilderness shares a portion of Mount Rainier National Park's southern boundary. The long rugged Tatoosh Ridge runs north-south out of the park to cross the Wilderness near the middle. The top of Tatoosh Ridge (6,310 feet) provides views in all directions and is the former site of a fire lookout built in 1932. About 25 feet of snow falls on the ridge during the winter, dusting a half-dozen small lakes.
Numerous streams cascade off the ridges into the Muddy Fork of the Cowlitz River or into Butter Creek, both of which funnel down to the Cowlitz River south of the Wilderness. Deer and elk winter along the Muddy Fork, and migrate into higher country in warmer seasons. Black bears may be seen foraging in the forest of hemlock, fir, and red cedar, and mountain goats live in the upper elevations.
The Tatoosh Range was used historically by Taidnapam (Upper Cowlitz) Indians. In mid-to-late August, Taidnapam families would climb up the ridge from fishing camps at the confluence of the Muddy Fork and Clear Fork Cowlitz Rivers, to hunt, gather materials for making baskets, and pick huckleberries for drying. The dried berries were transported to home villages for eating during the winter months. Archaeological evidence suggests that these high country treks were a long tradition among the local Indian people.
