Schonchin Butte is a cinder cone on the northern flank of Medicine Lake Volcano in the Cascade Range in northern California. Frothy lava, cooled in the air, created the large cinder cones throughout Lava Beds National Monument. It is named for Old Schonchin, a chief of the Modoc people during the late nineteenth century. Erupting more than 30,000 years ago, the volcano spewed ash and cinders into the air much like a can of soda when shaken. A lava spatter rampart is at the very top.
Newberry National Volcanic Monument was designated on November 5, 1990, to protect the area around the Newberry Volcano in the U.S. state of Oregon. The monument was created within the boundaries of the Deschutes National Forest, which is managed by the U.S. Forest Service, and includes 54,822 acres of lakes, lava flows, and geologic features in central Oregon.
Mount Bachelor, formerly named Bachelor Butte, is a dormant stratovolcano atop a shield volcano in the Cascade Volcanic Arc and the Cascade Range of central Oregon. Named Mount Bachelor because it stands apart from the nearby Three Sisters, it lies in the eastern segment of the central portion of the High Cascades, the eastern segment of the Cascade Range. The volcano lies at the northern end of the 15-mile (24 km) long Mount Bachelor Volcanic Chain, which underwent four major eruptive episodes during the Pleistocene and the Holocene. The United States Geological Survey considers Mount Bachelor a moderate threat, but Bachelor poses little threat of becoming an active volcano in the near future. It remains unclear whether the volcano is extinct or just inactive.
Mount Jefferson is a stratovolcano in the Cascade Volcanic Arc, part of the Cascade Range in the U.S. state of Oregon. The second highest mountain in Oregon, it is situated within Linn County, Jefferson County, and Marion County and forms part of the Mount Jefferson Wilderness. Due to the ruggedness of its surroundings, the mountain is one of the hardest volcanoes to reach in the Cascades. It is also a popular tourist destination despite its remoteness, with recreational activities including hiking, backpacking, mountaineering, and photography. Vegetation at Mount Jefferson is dominated by Douglas fir, silver fir, mountain hemlock, ponderosa pine, lodgepole pine, and several cedar species. Carnivores, insectivores, bats, rodents, deer, birds, and various other species inhabit the area.
Boring is an unincorporated community in Clackamas County, Oregon, United States. It is located along Oregon Route 212 in the foothills of the Cascade mountain range, approximately twelve miles (19 km) southeast of downtown Portland, and fourteen miles (23 km) northeast of Oregon City. A bedroom community, Boring is named after William Harrison Boring, a Union soldier and pioneer whose family built a farm in the area in 1856, before Oregon had received statehood.
An active volcano is a volcano that has erupted during the Holocene, is currently erupting, or has the potential to erupt in the future. A volcano that is not currently erupting but could erupt in the future is known as a dormant volcano. Volcanoes that will not erupt again are known as extinct volcanoes.
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.
The Boring Lava Field is a Plio-Pleistocene volcanic field with cinder cones, small shield volcanoes, and lava flows in the northern Willamette Valley of the U.S. state of Oregon and adjacent southwest Washington. The field got its name from the town of Boring, Oregon, located 12 miles (20 km) southeast of downtown Portland. Boring lies southeast of the densest cluster of lava vents. The zone became volcanically active about 2.7 million years ago, with long periods of eruptive activity interspersed with quiescence. Its last eruptions took place about 57,000 years ago at the Beacon Rock cinder cone volcano; the individual volcanic vents of the field are considered extinct, but the field itself is not.
Larch Mountain is an extinct volcano near Portland, Oregon. The name is misleading, as no western larch can be found there. It received that name when early lumbermen sold the noble fir wood as larch. The peak can be reached between May and November on paved Larch Mountain Road, 16 mi (26 km) east of Corbett, Oregon, although the road is closed during the winter and spring months. The road leading to Larch Mountain from the Historic Columbia River Highway is 14 miles long, which closed at milepost 10 from Nov. through late May or early June due to snow.
Lava Butte is a cinder cone in central Oregon, United States, just west of U.S. Route 97 between the towns of Bend, and Sunriver in Deschutes County. It is part of a system of small cinder cones on the northwest flank of Newberry Volcano, a massive shield volcano which rises to the southeast. The cinder cone is capped by a crater which extends about 60 feet (20 m) deep beneath its south rim, and 160 feet (50 m) deep from the 5,020-foot (1,530 m) summit on its north side. Lava Butte is part of the Newberry National Volcanic Monument.
Rocky Butte is an extinct cinder cone butte in Portland, Oregon, United States. It is also part of the Boring Lava Field, a group of volcanic vents and lava flows throughout Oregon and Washington state. The volcano erupted between 285,000 and 500,000 years ago.
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.
Pelican Butte is a steep-sided 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. Ice age glaciers carved a large cirque into the northeast flank of the mountain. Several proposals have been made over the last few decades for ski area development on the northeast flanks of the volcano, but there are no current plans to develop a ski area on the mountain.
Mount Tabor is an extinct volcanic vent with a city park on the volcano, located in Portland, Oregon's neighborhood of the same name. The name refers to Mount Tabor, Israel. It was named by Plympton Kelly, son of Oregon City pioneer resident Clinton Kelly.
Johnson Creek is a 25-mile (40 km) tributary of the Willamette River in the Portland metropolitan area of the U.S. state of Oregon. Part of the drainage basin of the Columbia River, its catchment consists of 54 square miles (140 km2) of mostly urban land occupied by about 180,000 people as of 2012. Passing through the cities of Gresham, Portland, and Milwaukie, the creek flows generally west from the foothills of the Cascade Range through sediments deposited by glacial floods on a substrate of basalt. Though polluted, it is free-flowing along its main stem and provides habitat for salmon and other migrating fish.
The Black Buttes, also known historically as the Sawtooth Rocks, make up an extinct stratovolcano in the Cascade Volcanic Arc in Whatcom County, Washington, United States. Glacially eroded remnants of this volcano rise above the Deming Glacier, part of the glacier system of the nearby volcano, Mount Baker. There are three major peaks — Colfax, Lincoln, and Seward — all of which can be climbed.
Clatsop Butte is an upland butte lying directly south of Powell Butte in southeast Portland, Oregon, United States. Clatsop Butte City Park, which occupies part of the butte, is at coordinates 45°28′28″N122°30′24″W at an elevation of 577 feet (176 m). Johnson Creek, Southeast Foster Road, and the Springwater Corridor Trail pass between Powell Butte and Clatsop Butte near Southeast 152nd Avenue.
The 40-Mile Loop is a partially completed greenway trail around and through Portland in the U.S. state of Oregon. It was proposed in 1903 by the Olmsted Brothers architecture firm as part of the development of Forest Park. One greenway expert calls it "one of the most creative and resourceful greenway projects in the country."
Mount Talbert is a volcanic cinder cone in Clackamas County, Oregon. It is part of the Boring Lava Field, a zone of ancient volcanic activity in the area around Portland. Its summit rises to an elevation of 740+ ft.
