Mount Aix is a 7,766-foot (2,367 m) mountain summit in Yakima County of Washington state.
The William O. Douglas Wilderness is a designated wilderness in Central Washington. It includes 169,081 acres (68,425 ha) located between the U.S. Route 12 and State Route 410 and is jointly administered by the Okanogan-Wenatchee National Forest and the Gifford Pinchot National Forest. It shares a boundary with the Mount Rainier National Park on the west; Norse Peak Wilderness lies to the north, Goat Rocks Wilderness to the south. Approximately 25 miles (40 km) of the Pacific Crest Trail travel along the Cascade Range crest within its boundaries. It contains scattered peaks, sharp ridges, steep slopes and hundreds of small lakes and potholes. Much of the wilderness is drained by tributaries of the Naches River.
The Bumping River is a tributary of the Naches River, in Washington in the United States. It flows down the east side of the Cascade Range, through Wenatchee National Forest and the William O. Douglas Wilderness. From its source at Fish Lake near Crag Mountain, it flows northeast to Bumping Lake, a natural lake enlarged and regulated by Bumping Lake Dam. Below the dam, the Bumping River continues flowing northeast. It is joined by the American River, its main tributary, a few miles above its mouth where it joins the Little Naches River to form the Naches River.
Naches Peak is a 6,452-foot (1,967 m) mountain summit located on the shared border of Mount Rainier National Park and William O. Douglas Wilderness. It is also on the shared border of Pierce County and Yakima County in Washington state. Naches Peak is situated on the crest of the Cascade Range and immediately southeast of Chinook Pass. Its nearest higher neighbor is Tahtlum Peak, 1.45 mi (2.33 km) to the east. The name Naches Peak was proposed by the Yakima Chamber of Commerce and approved by Asahel Curtis in 1927. The Naches Peak Loop Trail is a popular 3.5 mile trail encircling the peak. Precipitation runoff from the west side of Naches Peak drains into Chinook Creek, which is a tributary of the Ohanapecosh River, whereas the east side drains into tributaries of the American River.
Bismarck Peak 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. Bismarck Peak is situated east of the crest of the Cascade Range, southeast of Bumping Lake, south of Mount Aix, and northwest of Rimrock Lake. Its nearest higher peak is Mount Aix, 2.2 mi (3.5 km) to the north-northeast. Aix and Bismarck are the two highest peaks midway between Mount Rainier National Park and Yakima, Washington so they are quite prominent. Precipitation runoff from Bismarck Peak drains into tributaries of the Yakima River, thence to the Columbia River.
Spiral Butte is a cinder cone in Yakima County, Washington in the United States. The summit and most of the slopes are located within the William O. Douglas Wilderness of the Okanogan–Wenatchee National Forest between White Pass and Rimrock Lake. Historically the mountain has also been referred to as Big Peak. The present name stems from its orientation with a lava flow extending north out of the cone before spiraling east and then south. US 12 runs along the southern slope of the butte.
