Oregon's Matterhorns is an informal group of volcanoes in the Cascade Range, in the American state of Oregon, named after the original Matterhorn. The Pacific Crest Trail passes near all of the volcanoes which constitute Oregon's Matterhorns. [2] [3] [4]
Oregon's Matterhorns gained their name from Stephen Harris' book Fire Mountains of the West . [5] The name was inspired by similarities in form to the original Matterhorn in the Alps between Switzerland and Italy.
Oregon's Matterhorns should not be confused with the peak in the Wallowa Mountains (sometimes referred to as "The Alps of Oregon") [6] also called Matterhorn. [7]
It is a small set including all of: [8] [5]
The Cascade Range or Cascades is a major mountain range of western North America, extending from southern British Columbia through Washington and Oregon to Northern California. It includes both non-volcanic mountains, such as the North Cascades, and the notable volcanoes known as the High Cascades. The small part of the range in British Columbia is referred to as the Canadian Cascades or, locally, as the Cascade Mountains. The latter term is also sometimes used by Washington residents to refer to the Washington section of the Cascades in addition to North Cascades, the more usual U.S. term, as in North Cascades National Park. The highest peak in the range is Mount Rainier in Washington at 14,411 feet (4,392 m).
The Pacific Crest Trail (PCT), officially designated as the Pacific Crest National Scenic Trail, is a long-distance hiking and equestrian trail closely aligned with the highest portion of the Cascade and Sierra Nevada mountain ranges, which lie 100 to 150 miles east of the U.S. Pacific coast. The trail's southern terminus is next to the Mexico–United States border, just south of Campo, California, and its northern terminus is on the Canada–US border, upon which it continues unofficially to the Windy Joe Trail within Manning Park in British Columbia; it passes through the states of California, Oregon, and Washington.
Mount Thielsen, or Big Cowhorn, is an extinct shield volcano in the Oregon High Cascades, near Mount Bailey. Because eruptive activity ceased 250,000 years ago, glaciers have heavily eroded the volcano's structure, creating precipitous slopes and a horn-like peak. The spire-like shape of Thielsen attracts lightning strikes and creates fulgurite, an unusual mineral. The prominent horn forms a centerpiece for the Mount Thielsen Wilderness, a reserve for recreational activities such as skiing and hiking. Thielson is one of Oregon's Matterhorns.
Mount Bailey is a relatively young tephra cone and shield volcano in the Cascade Range, located on the opposite side of Diamond Lake from Mount Thielsen in southern Oregon, United States. Bailey consists of a 2,000-foot (610 m)-high main cone on top of an old basaltic andesite shield volcano. With a volume of 8 to 9 km3, Mount Bailey is slightly smaller than neighboring Diamond Peak. Mount Bailey is a popular destination for recreational activities. Well known in the Pacific Northwest region as a haven for skiing in the winter months, the mountain's transportation, instead of a conventional chairlift, is provided by snowcats—treaded, tractor-like vehicles that can ascend Bailey's steep, snow-covered slopes and carry skiers to the higher reaches of the mountain. In the summer months, a 5-mile (8 km) hiking trail gives foot access to Bailey's summit. Mount Bailey is one of Oregon's Matterhorns.
Three Fingered Jack is a summit of a shield volcano of the Cascade Range in the U.S. state of Oregon. Formed during the Pleistocene epoch, the mountain consists mainly of basaltic andesite lava and was heavily glaciated in the past. While other Oregon volcanoes that were heavily glaciated—such as Mount Washington and Mount Thielsen—display eroded volcanic necks, Three Fingered Jack's present summit is a comparatively narrow ridge of loose tephra supported by a dike only 10 feet (3.0 m) thick on a generally north–south axis. Glaciation exposed radiating dikes and plugs that support this summit. The volcano has long been inactive and is highly eroded.
Mount Washington is a deeply eroded volcano in the Cascade Range of Oregon. It lies within Deschutes and Linn counties and is surrounded by the Mount Washington Wilderness area.
Mount McLoughlin is a dormant steep-sided stratovolcano, or composite volcano, in the Cascade Range of southern Oregon and within the United States Sky Lakes Wilderness. It is one of the volcanic peaks in the Cascade Volcanic Arc, within the High Cascades sector. A prominent landmark for the Rogue River Valley, the mountain is north of Mount Shasta, and south-southeast of Crater Lake. It was named around 1838 after John McLoughlin, a Chief Factor for the Hudson's Bay Company. Mount McLouglin's prominence has made it a landmark to Native American populations for thousands of years.
The Pasayten Wilderness is a 531,539 acres (215,106 ha) protected area located within Okanogan–Wenatchee National Forest and Mount Baker National Forest in Washington state, centered on the Three Forks of the Pasayten River, a tributary of the Similkameen River. Although part of the wilderness lies in Mount Baker-Snoqualmie National Forest, the largest section falls within the boundaries of Okanogan National Forest, which has responsibility for the wilderness's management. The wilderness is bordered by the Stephen Mather Wilderness to the west. The northern boundary of the wilderness is the Canada–US border. Across the border are Manning Provincial Park and Cathedral Provincial Park. The wilderness area is adjacent to the Ross Lake National Recreation Area to the west, and North Cascades National Park beyond that. The Pacific Crest National Scenic Trail has its northernmost section in this wilderness. The western part of the wilderness features dramatic views and peaks of the northern Washington Cascade Mountains while the eastern section is known for its grasslands and Alpine tundra. The tallest point in the Pasayten is Jack Mountain.
Goat Rocks Wilderness is a U.S. wilderness area in Washington, United States, comprising 108,096 acres (43,745 ha) of Okanagan–Wenatchee National Forest and Gifford Pinchot National Forest on the crest of the Cascade Range south of U.S. Highway 12. Its central feature is a number of rugged peaks, the Goat Rocks, that are named after the numerous mountain goats that live in the area.
Umpqua National Forest, in southern Oregon's Cascade Range, covers an area of 983,129 acres (3,978.58 km2) in Douglas, Lane, and Jackson counties, and borders Crater Lake National Park. The four ranger districts for the forest are the Cottage Grove, Diamond Lake, North Umpqua, and Tiller ranger districts. The forest is managed by the United States Forest Service, headquartered in Roseburg.
The Diamond Peak Wilderness is a wilderness area straddling the Cascade crest and includes the Diamond Peak volcano. It is located within two National Forests - the Willamette National Forest on the west and the Deschutes National Forest on the east.
Diamond Peak is a volcano in Klamath and Lane counties of central Oregon in the United States. It is a shield volcano, though it might also be considered a modest stratocone. Diamond Peak forms part of the Cascade Volcanic Arc, a segment of the Cascade Range in western North America extending from southern British Columbia through Oregon to Northern California. Reaching an elevation of 8,748 feet (2,666 m), the mountain is located near Willamette Pass in the Diamond Peak Wilderness within the Deschutes and Willamette national forests. Surrounded by coniferous forest and visible in the skyline from foothills near Eugene, Diamond Peak offers a few climbing routes and can be scrambled. Diamond Peak is one of Oregon's Matterhorns.
The Deschutes National Forest is a United States National Forest located in parts of Deschutes, Klamath, Lake, and Jefferson counties in central Oregon. It comprises 1.8 million acres (7,300 km2) along the east side of the Cascade Range. In 1908, the Deschutes National Forest was established from parts of the Blue Mountains, Cascade, and Fremont National Forests. In 1911, parts of the Deschutes National Forest were split off to form the Ochoco and Paulina National Forests, and parts of the Cascade and Oregon National Forests were added to the Deschutes. In 1915, the lands of the Paulina National Forest were rejoined to the Deschutes National Forest. A 1993 Forest Service study estimated that the extent of old growth in the forest was 348,100 acres (140,900 ha). Within the boundaries of the Deschutes National Forest is the Newberry National Volcanic Monument, containing cinder cones, lava flows, and lava tubes. The Deschutes National Forest as a whole contains in excess of 250 known caves. The forest also contains five wilderness areas, six National Wild and Scenic Rivers, the Oregon Cascade Recreation Area, and the Metolius Conservation Area. Forest headquarters are located in Bend, Oregon. There are local ranger district offices in Bend, Crescent, and Sisters.
The Mount Thielsen Wilderness is a wilderness area located on and around Mount Thielsen in the southern Cascade Range of Oregon in the United States. It is located within the Deschutes, Umpqua, and Fremont–Winema national forests. It was established by the United States Congress in 1984 and comprises 55,100 acres (22,300 ha).
Howlock Mountain is a heavily eroded shield volcano in the Cascade Range of central Oregon, located along the Cascade Crest just north of Mount Thielsen. Ice Age glaciers eroded away most of the flanks of the volcano, leaving numerous deep cirques surrounding a central ridge capped by several horns. The summit of Howlock Mountain lies along the border between Douglas County and Klamath County.
Union Peak is a heavily eroded shield volcano in the Cascade Range of central Oregon, located along the Cascade Crest less than 7 miles (11.3 km) southwest of the rim of Crater Lake. Ice age glaciers eroded away most of the flanks of the volcano, leaving numerous deep cirques surrounding a central glacial horn. This is the same process that formed the summit horns of Three Fingered Jack, Mount Washington, Howlock Mountain, and Mount Thielsen from other shield volcanoes farther north in the Oregon Cascades.
The Cascades ecoregion is a Level III ecoregion designated by the United States Environmental Protection Agency (EPA) in the U.S. states of Washington, Oregon, and California. Somewhat smaller than the Cascade mountain range for which it is named, the ecoregion extends north to Snoqualmie Pass, near Seattle, and south to Hayden Pass, near the Oregon-California border, including the peaks and western slopes of most of the High Cascades. A discontiguous section is located on Mount Shasta in California.
Sacajawea Peak is a peak in the Wallowa Mountains, in the U.S. state of Oregon. It is in the Eagle Cap Wilderness and the Wallowa–Whitman National Forest.
The Oregon Skyline Trail is a long-distance trail in the Cascade Mountains of Oregon. The trail extends 428 miles (689 km) from Cascade Locks on the Columbia River south to Siskiyou Summit near the Oregon-California border. The century-old trail is a foot and equestrian path that passes through nine wilderness areas, Crater Lake National Park, and Cascade-Siskiyou National Monument. Historically known as the Oregon Skyline Trail or Skyline Trail, the entire length of the trail was incorporated into the Pacific Crest National Scenic Trail in 1968.
