Cinder Cone is a cinder cone volcano in Lassen Volcanic National Park within the United States. It is located about 10 mi (16 km) northeast of Lassen Peak and provides an excellent view of Brokeoff Mountain, Lassen Peak, and Chaos Crags.
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.
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.
Pilot Butte is a lava dome that was created from an extinct volcano located in Bend, Oregon. It is a cinder cone butte which rises nearly 500 feet (150 m) above the surrounding plains. Bend is one of six cities in the United States to have a volcano within its boundaries. The other examples are Mount Tabor in Portland, Oregon, Jackson Volcano in Jackson, Mississippi, Diamond Head in Honolulu, Glassford Hill in Prescott Valley and Pilot Knob in Austin, Texas.
Mount Baker Wilderness is a 119,989-acre (48,558 ha) wilderness area within the Mount Baker-Snoqualmie National Forest in the western Cascade Range of northern Washington state. Its eastern border is shared with the boundary of the Stephen Mather Wilderness and North Cascades National Park for a distance of 40 miles. The wilderness extends from State Route 20 north to the Canada–US border. On the west, it is bounded by the foothills of the Puget Sound lowlands.
Black Butte is an extinct stratovolcano in the U.S. state of Oregon. Located in Jefferson County, it is part of Deschutes National Forest. Black Butte forms part of the Cascade volcanic arc. The butte lies just south of the Metolius Springs, which merge to form the headwaters of the Metolius River. The Metolius River's basin sustains a wide array of plant life, large and small mammals, and more than 80 bird species.
Powell Butte is an extinct cinder cone butte in Portland, Oregon, United States. It is part of the Boring Lava Field, which includes more than 80 small volcanic edifices and lava flows in the Portland–Vancouver metropolitan area. The region around Powell Butte has a cool climate, and the butte and its surroundings feature meadows, rivers, and mixed forests. Powell Butte hosts the Powell Butte Nature Park, which includes about 612 acres (2.48 km2) of trails for biking, hiking, and horseback riding.
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.
Hoodoo Butte is a cinder cone butte in the Cascade Range of northern Oregon, located near Santiam Pass. Immediately to the east lies Hayrick Butte, a prime example of a tuya; the two mountains' names were likely mistaken for each other, but stuck with them over time. The area has been subjected to a number of historic fires. Hoodoo is sometimes considered a subfeature of the Mount Washington shield volcano, and it forms part of the Sisters Reach, which extends from South Cinder Peak to Crane Prairie Reservoir, running for 56 miles (90 km). This region has a high vent density, with many mafic volcanoes of Pleistocene to Holocene age, such as Hoodoo. While Hoodoo has an intact summit crater that was blocked from erosion by glaciers, it has an irregular topography, giving it an open appearance.
Maiden Peak is a steep-sided shield volcano in the Cascade Range of central Oregon. It is the highest point in the 43-mile (69 km) distance between Mount Bachelor and Diamond Peak. Ice Age glaciers carved a large cirque into the northeast flank of the mountain, exposing magma which hardened in the volcano's conduits to form the numerous rock pinnacles now found in the upper part of the cirque.
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.
Hogg Rock is a tuya volcano and lava dome in the Cascade Range of northern Oregon, located close to Santiam Pass. Produced by magma with an intermediate andesite composition, it has steep slopes and thick glassy margins. Hogg Rock exhibits normal magnetic polarity and is probably about 80,000 years old.
Pelican Butte is a steep-sided dormant shield volcano in the Cascade Range of southern Oregon. It is located 28 miles (45 km) due south of Crater Lake and 12 miles (19 km) northeast of Mount McLoughlin, and rises over 3,800 feet (1,200 m) directly above the shore of Upper Klamath Lake. Ice age glaciers carved a large cirque into the northeast flank of the mountain, forming a steep bowl which is popular in winter with backcountry skiers and snowmobilers. Several proposals have been made over the last few decades for ski area development on the northeast flanks, but none of the proposals has obtained the regulatory approval from the United States Forest Service necessary to proceed with construction. If the ski area is ever built, its skiable vertical of over 3,800 feet (1,200 m) would be the largest in Oregon exceeding the 3,590 feet (1,090
Aspen Butte is a steep-sided shield volcano in the Cascade Range of southern Oregon. It is located 15 miles (24 km) south of Pelican Butte and 15 miles (24 km) southeast of Mount McLoughlin. It rises over 4,000 feet (1,200 m) above the nearby shore of Upper Klamath Lake. Ice Age glaciers carved three large cirques into the north and northeast flanks of the mountain removing most of the original summit area including any evidence of a crater. The summit is now the high point along the curving ridge which bounds the southern edge of the cirques above steep cliffs.
The Twin Buttes are two volcanic cinder cones located in the Cascade Mountain Range in Shasta County, California. The volcanoes are part of the Bidwell Spring chain and lie within a region that was a hotbed of Quaternary volcanic activity. Formed during the Pleistocene between 25,000 and 15,000 years ago, the volcanoes erupted lava flows that coursed toward the Burney Mountain lava dome, covering an area of 3.9 square miles (10.1 km2). These lava flows are made of basalt and dacite; the volcanoes also erupted cinder and volcanic ash that reached eastward. The volcanoes were still monitored by the United States Geological Survey for deformation, an indicator of pre-eruptive activity, as of 2012, but they are considered to have "low to very low" threat potential for future eruptive activity.
The Davis Lake volcanic field, is a volcanic field with a group of andesitic cinder cones, lava flows and basaltic andesite shield volcano. The field is located east of the Cascade Range of Oregon, United States.
Spiral Butte is a cinder cone in Yakima County, Washington in the United States. The summit and most of the slopes are located within the William O. Douglas Wilderness of the Okanogan–Wenatchee National Forest between White Pass and Rimrock Lake. Historically the mountain has also been referred to as Big Peak. The present name stems from its orientation with a lava flow extending north out of the cone before spiraling east and then south. US 12 runs along the southern slope of the butte.
