Chiwawa Mountain is an 8,459-foot (2,578-metre) mountain summit located in the Glacier Peak Wilderness of the North Cascades in Washington state. [4] The mountain is situated on the crest of the Cascade Range, on the shared border of Snohomish County and Chelan County, also straddling the boundary between the Mount Baker-Snoqualmie National Forest and the Wenatchee National Forest. Its nearest higher peak is Fortress Mountain, 1.12 mi (1.80 km) to the west. Chiwawa Mountain is a triple divide peak, so precipitation runoff from it drains northeast to Lake Chelan via Railroad Creek; northwest into Miners Creek which is a tributary of the Suiattle River; and south into the Chiwawa River headwaters. The mountain's name is taken from the river's name, which was applied by Albert Hale Sylvester (1871-1944), a pioneer surveyor, explorer, topographer, and forest supervisor in the Cascades. [3] Chiwawa comes from the Columbia-Moses language and means a kind of creek ("wawa" creek). [5]
Chiwawa Mountain is located in the Cloudy Pass batholith, an intrusive formation that was formed approximately 20 million years ago, during the early Miocene. [3] [6] During the Pleistocene period dating back over two million years ago, glaciation advancing and retreating repeatedly scoured and shaped the landscape. [7] Remnants of the Lyman Glacier remain on the northeast slope of Chiwawa Mountain. Glaciation was most prevalent approximately 18,000 years ago, and most valleys were ice-free by 12,000 years ago. [3] Uplift and faulting in combination with glaciation have been the dominant processes which have created the tall peaks and deep valleys of the North Cascades area. Subduction and tectonic activity in the area began during the late cretaceous period, about 90 million years ago. Extensive volcanic activity began to take place in the oligocene, about 35 million years ago. [8] Glacier Peak, a stratovolcano that is 10.0 mi (16.1 km) southwest of Chiwawa Mountain, began forming in the mid-Pleistocene. [3] Due to Glacier Peak's proximity to Chiwawa Mountain, volcanic ash is common in the area.
Chiwawa Mountain is located in the marine west coast climate zone of western North America. [3] Most weather fronts coming off the Pacific Ocean travel northeast toward the Cascade Mountains. As fronts approach the North Cascades, they are forced upward by the peaks of the Cascade Range (orographic lift), causing them to drop their moisture in the form of rain or snow onto the Cascades. As a result, the west side of the North Cascades experiences high precipitation, especially during the winter months in the form of snowfall. [3] Because of maritime influence, snow tends to be wet and heavy, resulting in high avalanche danger. [3] During winter months, weather is usually cloudy, but, due to high pressure systems over the Pacific Ocean that intensify during summer months, there is often little or no cloud cover during the summer. [3] Due to its temperate climate and proximity to the Pacific Ocean, areas west of the Cascade Crest very rarely experience temperatures below 0 °F (−18 °C) or above 80 °F (27 °C). [3]
Fortress Mountain is an 8,679-foot (2,645 m) peak in the Cascade Range located about 15 miles (24 km) west of Lake Chelan in Chelan/Snohomish Counties, Washington, United States. It straddles the border between the Mount Baker-Snoqualmie National Forest and the Wenatchee National Forest, and is also part of the Glacier Peak Wilderness. Fortress Mountain is the highest point on Chiwawa Ridge, and other notable peaks on this ridge include Napeequa Peak, Buck Mountain, Brahma Peak, Bandit Peak, Mount Berge, Helmet Butte, and Chiwawa Mountain.
Hinkhouse Peak is a 7,566-foot-elevation (2,306-meter) mountain summit located on the shared border of Okanogan County and Chelan County in Washington state. It is part of the Okanogan Range which is a sub-range of the North Cascades Range. Hinkhouse Peak is situated on land administered by the Okanogan–Wenatchee National Forest. The nearest higher neighbor is Liberty Bell Mountain, 1.52 miles (2.45 km) to the south. Hinkhouse Peak is situated north of Washington Pass, at the east end of a high ridge which connects to Cutthroat Peak. A high ridge extending northeast connects it to Constitution Crags. Most precipitation runoff from the peak drains into Early Winters Creek which is a tributary of the Methow River, but the south slope drains into a tributary of the Chelan River. Topographic relief is significant as it rises nearly 3,200 feet above Early Winters Creek in approximately one mile (1.6 km).
Sitting Bull Mountain is a 7,759-foot (2,365-metre) double summit mountain in the North Cascades of Washington state. The north summit is higher than the south peak, and easier to climb, however neither peak sees much climbing activity. Sitting Bull Mountain is located 2.1 mi (3.4 km) northwest of Suiattle Pass in the heart of the Glacier Peak Wilderness. Its nearest higher peak is Plummer Mountain, 1.51 mi (2.43 km) to the south-southwest. The mountain is situated on the crest of the Cascade Range, on the shared border of Snohomish County and Chelan County. Precipitation runoff from Sitting Bull Mountain drains east into Agnes Creek which is a tributary of the Stehekin River, or west into Canyon Creek which is a tributary of the Suiattle River.
Dumbell Mountain is an 8,416-foot (2,565-metre) double summit massif located in the Glacier Peak Wilderness of the North Cascades, in Chelan County of Washington state. The Dumbell summit is slightly higher than the northeast subpeak (8,408 ft) which is unofficially called Greenwood Mountain. The nearest higher neighbor is Chiwawa Mountain, 2.4 mi (3.9 km) to the east-southeast. Precipitation runoff from Dumbell Mountain drains into tributaries of the Chelan River and the Wenatchee River. The mountain's descriptive name was applied by Albert Hale Sylvester (1871-1944), pioneer surveyor, explorer, topographer, and forest supervisor in the Cascades.

Precipitation runoff from the mountain drains into Buck Creek, Chiwawa River, and Napeequa River, each a tributary of the Wenatchee River. The mountain's toponym was applied by Albert Hale Sylvester (1871-1944), pioneer surveyor, explorer, topographer, and forest supervisor in the Cascades.
