Oregon's Matterhorns
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. Origin of the name Oregon's Matterhorns gained their name from Stephen Harris' book '' Fire Mountains of the West''. 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") also called Matterhorn.

Mount Washington (Oregon)
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. Like the rest of the Oregon Cascades, Mount Washington was produced by the subduction of the oceanic Juan de Fuca tectonic plate under the continental North American tectonic plate, forming during the late Pleistocene. Made mostly of mafic (rich in magnesium and iron) volcanic rock like subalkaline basalt and basaltic andesite, it has a volcanic plug occupying its summit cone and numerous dikes. It is surrounded by other volcanic features such as cinder cones and spatter cones. The volcano's last eruptions took place from spatter cones about 1,350 years ago, generating basaltic andesite lava deposits. Mount Washington has barren surroundings, which have seen little historical recreational use. A wagon road at McKenzie Pass was built in 1872, which was later paved during the 1930s. On August 2 ...

Wallowa Mountains
The Wallowa Mountains () are a mountain range located in the Columbia Plateau of northeastern Oregon in the United States. The range runs approximately northwest to southeast in southwestern Wallowa County and eastern Union County between the Blue Mountains to the west and the Snake River to the east. The range is sometimes considered to be an eastern spur of the Blue Mountains, and it is known as the "Alps of Oregon". Much of the range is designated as the Eagle Cap Wilderness, part of the Wallowa–Whitman National Forest. Geography The range is drained by the Wallowa River, which flows from the north side of the mountains, and its tributary the Minam River, which flows through the west side of the range. The Imnaha River flows from the east side of the range. The highest point in the range is Sacajawea Peak, which is above sea level. Sacajawea is the sixth highest mountain in Oregon and the state's highest peak outside of the Cascade Range. Geology Many geologists be ...

McKenzie Pass
McKenzie Pass, elevation , is a mountain pass in the Cascade Range in central Oregon in the United States. It is located at the border of Linn and Deschutes counties, approximately northwest of Bend, between the Three Sisters to the south and Mount Washington to the north. Oregon Route 242 goes over the pass. At the summit of the pass, Oregon Route 242 crosses a lava flow just west of Sisters. Surrounded by lava, the Dee Wright Observatory was constructed in 1935 by Civilian Conservation Corps workers and named after their foreman. Visitors climb to the observatory to view the Cascade peaks visible from McKenzie Pass. Also near the summit is Clear Lake, a renowned location for fresh-water diving. Highway 242 is not recommended for large trucks, trailers or motor homes due to numerous tight switchbacks. The pass is closed from November to July due to snow. The pass is named for Donald McKenzie, a Scottish Canadian fur trader who explored parts of the Pacific Northwe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Diamond Peak Wilderness
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. Designation On February 5, 1957, the Forest Service established the Diamond Peak Wild Area. Upon passage of the federal Wilderness Act in 1964 it was reclassified as wilderness. With the passage of the Oregon Wilderness Act of 1984, Diamond Peak Wilderness increased in size to its present .''Central Oregon Wilderness Areas (Cascades to the Coast)'', by Donna Aitkenhead, p4. 14-15 Geography At , Diamond Peak is the highest peak in the wilderness.

Diamond Lake (Oregon)
Diamond Lake is a natural body of water in the southern part of the U.S. state of Oregon. It lies near the junction of Oregon Route 138 and Oregon Route 230 in the Umpqua National Forest in Douglas County. It is located between Mount Bailey to the west and Mount Thielsen to the east; it is just north of Crater Lake National Park. The outlet of the lake is at its north end. From there, water flows via Diamond Lake Creek into the North Umpqua River and ultimately to the Pacific Ocean. Diamond Lake was named for John Diamond, for whom Diamond Peak is also named. He saw the lake in 1852 while on the summit of Diamond Peak. Diamond was a pioneer settler of Coburg, Oregon, and part of a party opening a road between the Middle Fork Willamette River and Idaho as an immigration route. An adjacent post office named Diamond Lake, Oregon, was established in 1925 and ran until 1956, when it was changed to a summer-only office. Diamond Lake is also the host for the Tour de Diamond, a c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 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.

Three Fingered Jack (Oregon)
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 (geology), epoch, the mountain consists mainly of basaltic andesite lava and was heavily glacier, glaciated in the past. While other Oregon volcanoes that were heavily glaciated—such as Mount Washington (Oregon), Mount Washington and Mount Thielsen—display eroded Volcanic plug, volcanic necks, Three Fingered Jack's present summit is a comparatively narrow ridge of loose tephra supported by a dike (geology), dike only 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. Three Fingered Jack has diverse flora, fauna, and fungi. The Molala people, one of the Indigenous peoples of the Northwest Plateau, indigenous groups in the northwestern United States, historically inhabited the area around the volcano.
