Middle Peak is a 7,464-foot-elevation (2,275-meter) mountain summit located in the North Cascades in Whatcom County of Washington state, United States.
Middle Peak is set one-third mile south of the Canada–United States border near Boundary Monument No. 60. It is within North Cascades National Park and Stephen Mather Wilderness. This sharp peak is situated immediately west of Hanging Lake, four miles southwest of the southern tip of Chilliwack Lake, and 3.4 mi (5.5 km) southeast of Mount Rexford. The nearest higher neighbor is Mount Lindeman, 1.6 mi (2.6 km) to the northeast, and Mount Redoubt is 8.1 mi (13.0 km) to the southeast. [2] Other peaks which can be seen from the summit include Mount Baker, Mount Shuksan, Mount Challenger, Copper Mountain, and many more. Middle Peak is more notable for its steep rise above local terrain than for its absolute elevation. Topographic relief is significant as the summit rises 4,000 feet above the Little Chilliwack River in two miles. Precipitation runoff from this mountain drains into the Little Chilliwack and headwaters of Centre Creek which are both tributaries of the Chilliwack River.
The first ascent of the peak's 7,160-foot-elevation southwest summit was made July 8, 1859, by surveyor Henry Custer and party during a reconnaissance. [1] [5] The first ascent of Middle Peak was made June 30, 1908, by James J. McArthur, a Canadian surveyor of the International Boundary Commission. [1] Paragliders have lifted off from the summit and landed at the upper end of Chilliwack Lake. [1]
Middle Peak is located in the marine west coast climate zone of western North America. [1] Most weather fronts originating in 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 snowfall 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. [1] Because of maritime influence, snow tends to be wet and heavy, resulting in high avalanche danger. [1] 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. [1] 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). [1] This climate supports small glacial remnants on the north slope above Hanging Lake. The months July through September offer the most favorable weather for viewing or climbing this peak.
The North Cascades feature some of the most rugged topography in the Cascade Range with craggy peaks, ridges, and deep glacial valleys. Geological events occurring many years ago created the diverse topography and drastic elevation changes over the Cascade Range leading to various climate differences.
The history of the formation of the Cascade Mountains dates back millions of years ago to the late Eocene Epoch. [6] With the North American Plate overriding the Pacific Plate, episodes of volcanic igneous activity persisted. [6] In addition, small fragments of the oceanic and continental lithosphere called terranes created the North Cascades about 50 million years ago. [6]
During the Pleistocene period dating back over two million years ago, glaciation advancing and retreating repeatedly scoured the landscape leaving deposits of rock debris. [6] The U-shaped cross section of the river valleys is a result of recent glaciation. 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.
Mount Pugh is a peak near the western edge of the North Cascades, in Washington state. It is located 12.2 miles (19.6 km) west of Glacier Peak, one of the Cascade stratovolcanoes. It rises out of the confluence of the White Chuck River and the Sauk River, giving it very low footings. For example, it rises 6,150 feet (1,875 m) above the Sauk River Valley in just over 2 horizontal miles (3.2 km); its rise over the White Chuck River is almost as dramatic. The mountain is named for John Pugh, who settled nearby, in 1891.
Buckner Mountain is a tall peak in the North Cascades of Washington state and in the Stephen Mather Wilderness of North Cascades National Park. At 9,114 feet (2,778 m) in elevation it is the highest in Skagit County and one of about ten of Washington's non-volcanic peaks above 9,000 feet high. It is ranked as the 14th highest peak in the state, and the third highest peak in North Cascades National Park.
Chimney Rock is a mountain located in the Alpine Lakes Wilderness of the Central Cascade Range in western Washington, United States. The mountain has two main summits, a northeast spire and a central spire, as well as a minor south peak. Situated 10 miles NNE of Snoqualmie Pass, with its craggy appearance Chimney Rock is the most distinctive peak on the crest dividing the Snoqualmie River and Yakima River drainage areas. Lemah Mountain is to the south on the crest, and Summit Chief Mountain to the northeast. Overcoat Peak is off the main ridge just to the north of Chimney Rock. The mountain has three glaciers: the Overcoat Glacier on the north, the Chimney Glacier on the south and east, and an unnamed glacier on the east side of the North Peak.
Mount Larrabee is a 7,865-foot (2,397-metre) Skagit Range mountain summit situated 1.4 mile south of the Canada–United States border, in the North Cascades of Washington state. It is located immediately southeast of American Border Peak within the Mount Baker Wilderness, which is part of the Mount Baker-Snoqualmie National Forest, and near North Cascades National Park. It is notable for its reddish coloring caused by oxidation of Iron in the rock. The rock consists of reddish interbedded and interfolded phyllites and greenstone. Originally known as Red Mountain, the name was changed in 1951 to honor Charles F. Larrabee (1895–1950), of the prominent Larrabee family of Bellingham, Washington. The toponym was officially adopted in 1951 by the U.S. Board on Geographic Names.
Tomyhoi Peak is a 7,439-foot (2,267-metre) Skagit Range mountain situated one mile south of the Canada–United States border, in the North Cascades of Washington state. It is located west of Mount Larrabee and within the Mount Baker Wilderness, which is part of the Mount Baker-Snoqualmie National Forest. This mountain's toponym was officially adopted in 1913 by the U.S. Board on Geographic Names.
Ruby Mountain is a prominent 7,412-foot (2,259-metre) mountain summit located in the North Cascades Range of Washington state. It is situated in Ross Lake National Recreation Area which is part of the North Cascades National Park Complex. The Diablo Lake Overlook along the North Cascades Highway is at the foot of the mountain. The nearest higher peak is Colonial Peak, 4.2 miles (6.8 km) to the southwest. Precipitation runoff on the east side of the mountain drains to Ross Lake via Ruby Creek, whereas the west side of the mountain drains to Diablo Lake via Thunder Creek. Topographic relief is significant as the summit rises 6,200 feet above Diablo Lake in approximately two miles.
Devils Thumb is a 5,172-foot-elevation (1,576-meter) mountain summit in Snohomish County, Washington, United States. It is located near the western edge of the North Cascades, 10 miles south of Darrington, Washington, and 20 miles west of Glacier Peak which is one of the Cascade stratovolcanoes. The peak is situated on land administered by Mount Baker-Snoqualmie National Forest. The nearest higher neighbor is Devils Peak, 0.79 miles (1.27 km) to the southwest. Precipitation runoff from the south slope of Devils Thumb drains into Coal Creek which is a tributary of the Stillaguamish River, whereas the other slopes drain into Helena Creek → Clear Creek → Sauk River. Although modest in elevation, topographic relief is significant as the summit rises over 2,100 feet above Helena Lake in one-half mile (0.8 km). This mountain's toponym has been officially adopted by the United States Board on Geographic Names.
Big Snow Mountain is a prominent 6,680-foot (2,040-metre) mountain summit located 7 mi (11 km) north of Snoqualmie Pass in the Alpine Lakes Wilderness in eastern King County of Washington state.

Mount Lago is a prominent 8,745-foot (2,665-metre) mountain summit located in the Okanogan Range of the North Cascades, in Okanogan County of Washington state. The mountain is situated on the eastern side of the Cascade crest, in the Pasayten Wilderness, on land managed by the Okanogan–Wenatchee National Forest. The nearest higher peak is Jack Mountain, 19.5 miles (31.4 km) to the west-southwest. Mount Lago is the highest summit of the Okanogan Range, and follows only Jack Mountain {9,075 ft} as the highest peak in the Pasayten Wilderness. Lago is the fourth-most prominent mountain in the Pasayten Wilderness. Precipitation runoff from the mountain drains into tributaries of the Pasayten River and Methow River. The mountain was named for Lage Wernstedt (1878–1959), a Forest Service surveyor who made numerous first ascents of the mountains he was mapping in the North Cascades. Lago, is a play on the way Americans pronounced his name. Lage, pronounced Loggy, had a son named Lago.
