Bismarck Peak[3] is a 7,585-foot-elevation (2,312 meter) mountain summit in Yakima County of Washington state.

It is also 24 miles east-southeast of Mount Rainier and centrally located in the William O. Douglas Wilderness, on land administered by the Wenatchee National Forest.

Its nearest higher peak is Mount Aix, 2.2 mi (3.5 km) to the north-northeast.

[1] Aix and Bismarck are the two highest peaks midway between Mount Rainier National Park and Yakima, Washington so they are quite prominent.

Most weather fronts originating in the Pacific Ocean travel northeast toward the Cascade Mountains.
