Spider Mountain is an 8,317-foot (2,535-metre) mountain summit located in the Glacier Peak Wilderness in western Chelan County of Washington state. [4] It is part of the North Cascades, which is a subset of the Cascade Range. Meltwater from the Spider Glacier on the steep north face, and other surface runoff from the mountain drains into Flat Creek, which is a tributary of the Stehekin River. Topographic relief is significant as the summit rises 4,200 feet (1,300 meters) above West Fork Flat Creek in one mile (1.6 km). The nearest higher neighbor is Mount Formidable 1.5 miles (2.4 km) to the west. [2] The Middle Cascade Glacier lies between these two mountains and the Ptarmigan Traverse passes between the two.
Spider Mountain is located in the marine west coast climate zone of western North America. [3] Weather fronts coming inland from the Pacific Ocean travel northeast toward the Cascade Mountains. As fronts approach the North Cascades, they are forced upward by the peaks (orographic lift), causing them to drop their moisture in the form of rain or snow onto the Cascades. As a result, the North Cascades experience high precipitation, especially during the winter months in the form of snowfall. 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] The months of July through September offer the most favorable weather for climbing or viewing this peak.
The North Cascades features some of the most rugged topography in the Cascade Range with craggy peaks and ridges, deep glacial valleys, and granite spires. 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. [5] With the North American Plate overriding the Pacific Plate, episodes of volcanic igneous activity persisted. [5] In addition, small fragments of the oceanic and continental lithosphere called terranes created the North Cascades about 50 million years ago. [5]
During the Pleistocene period dating back over two million years ago, glaciation advancing and retreating repeatedly scoured the landscape leaving deposits of rock debris. [5] 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.
Silver Star Mountain is an 8,876-foot (2,705-metre) mountain located in Okanogan County, Washington. The mountain is part of the Methow Mountains, a subset of the Cascade Range. Silver Star is the dominant feature in the Washington Pass area and visible from the North Cascades Highway. It was first climbed by Lage Wernstedt in 1926.
Sahale Mountain is a jagged, glaciated mountain, in North Cascades National Park, in northern Washington state. The summit of Sahale Mountain is referred to as Sahale Peak. It is 0.3 miles (0.48 km) south of its higher neighbor, Boston Peak, and the saddle between the two is 80 feet (24 m) lower than Sahale's summit. Quien Sabe Glacier is to the west of the ridge between the two peaks while Davenport Glacier is in a cirque east of this ridge and above Horseshoe Basin. Sahale Glacier is south of the summit and east of Sahale Arm, a ridge that extends southwest from Sahale to Cascade Pass. The name Sahale may originate from a Northwest Native American word meaning "high place," "falcon," or "sacred."
Dragontail Peak, also known as Dragon Tail, is a mountain in the Stuart Range, in Chelan County, Washington. While climbing an adjacent peak, Lex Maxwell, Bob McCall, and Bill Prater remarked that the needles on the crest, southwest of the summit, resembled a "dragon tail". The name was officially accepted in 1955. On the mountain's northeast flank lies Colchuck Lake which drains into Mountaineer Creek, and Colchuck Glacier lies below the western slopes of the peak. On its south side the mountain drops steeply to Ingalls Creek, which flows about 5,800 feet (1,800 m) below the summit.
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.
Kimtah Peak, elevation 8,600+ feet, is in North Cascades National Park in the U.S. state of Washington. Kimtah Peak is a summit along a ridge known as Ragged Ridge. Kimtah Glacier is on the northwest slopes of the peak, while Katsuk Glacier is to the northeast.
Frisco Mountain is a 7,760-foot (2,365-metre) mountain summit in the Cascade Range in the U.S. state of Washington. It is located two miles southwest of Rainy Pass on the borders of the Stephen Mather Wilderness and North Cascades National Park. First climbed by surveyor Lage Wernstedt in 1926, the mountain derives its name from a mining claim on the south side that was worked in the 1920s. Its nearest higher peak is Rainy Peak, 0.54 mi (0.87 km) to the east-southeast. Precipitation runoff from Frisco Mountain drains into Rainy Lake and tributaries of Bridge Creek. The retreating Lyall Glacier in its northeast cirque contributes to waterfalls which tumble 1,000 ft (300 m) into Rainy Lake.
Mount Misch is a remote 7,435 ft mountain summit in the North Cascades, in Skagit County of Washington state. It is the highest point of the Buckindy Range, or Buckindy Ridge. It is located 19 miles east-northeast of Darrington, Washington, and 15 miles north-northwest of Glacier Peak which is one of the Cascade stratovolcanoes. It is situated in the Glacier Peak Wilderness on land administered by the Mount Baker-Snoqualmie National Forest. Mount Misch was named by mountaineer and author Fred Beckey for his friend Peter Misch (1909-1987), University of Washington geology professor and mountaineer, who was renowned for his study of the North Cascades. Precipitation runoff from Mount Misch and the unnamed Goat Creek glacier on its east slope drains into tributaries of the Suiattle River and ultimately the Skagit River.
Hurry-up Peak is a 7,821-foot-elevation summit located on the shared boundary of Skagit County and Chelan County in Washington state. It is positioned on the crest of the North Cascades Range, and is set at the northern end of the Ptarmigan Traverse. Hurry-up Peak is situated southeast of Cascade Pass on the shared border of North Cascades National Park and Glacier Peak Wilderness. The nearest higher peak is Spider Mountain, 1.49 miles (2.40 km) to the south, with Magic Mountain 0.83 miles (1.34 km) to the north, and Trapper Mountain 0.7 miles (1.1 km) to the east. The S Glacier rests on the eastern flank of the peak and meltwater from it drains into Trapper Lake. Precipitation runoff on the east side the mountain drains into tributaries of the Stehekin River, while precipitation drains into the Cascade River from the west side. Ess Mountain and S Mountain are variant names for Hurry-up Peak. This geographical feature's toponym was officially adopted in 1969 by the U.S. Board on Geographic Names.
