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 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.
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 Sycan River is a tributary, about 75 miles (121 km) long, of the Sprague River in the U.S. state of Oregon. The headwaters are in highlands in the Fremont National Forest south of Summer Lake. The river runs northwest into the Sycan Marsh in southern Lake County, from which it flows generally southwest to join the Sprague River near Beatty, in Klamath County. The uppermost 59 miles (95 km) of the stream are part of the National Wild and Scenic Rivers System.
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 Link River is a short river connecting Upper Klamath Lake to Lake Ewauna in the city of Klamath Falls in the U.S. state of Oregon. Draining a basin of 3,810 square miles (9,900 km2), the river begins at the southern end of Klamath Lake and flows a short distance to the Link River Dam and continues 1.5 miles (2.4 km) to the head of Lake Ewauna. The "falls" from which Klamath Falls derives its name, and which in reality are best described as rapids rather than falls, are visible a short distance below the dam, though the water flow is generally insufficient to provide water flow over the rocks. The Klamath River begins at the narrow southern end of Lake Ewauna and flows 253 miles (407 km) from there to the Pacific Ocean.
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.
Yamsay Mountain is a large shield volcano in the Cascade Range of south-central Oregon, located about 35 miles (56 km) east of Crater Lake on the border between Klamath County and Lake County. It is part of the Cascade Volcanic Arc but is located in a mountain range 30 to 50 miles behind the main Cascade volcanic front. The best known members of this enigmatic arc are the massive shields of Newberry Volcano, about 55 miles (89 km) farther north in Oregon, and Medicine Lake Volcano, about 80 miles (130 km) south in Northern California. Yamsay is the highest volcano in the eastern arc, almost 300 feet (90 m) higher than Newberry and Medicine Lake.
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 m) of Timberline Lodge ski area on Mount Hood.
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.
Battle Ax is a shield volcano in the West Cascade Range of Oregon. The shield is mostly made of andesite. The summit, which can be reached via the Battle Ax Mountain trail, marks the boundary between the Mount Hood National Forest and the Willamette National Forest as well as the boundary between the Opal Creek Wilderness and the Bull of the Woods Wilderness.
Big Butte Creek is a 12-mile-long (19 km) tributary of the Rogue River in the U.S. state of Oregon. It drains approximately 245 square miles (635 km2) of Jackson County. Its two forks, the North Fork and the South Fork, both begin high in the Cascade Range near Mount McLoughlin. Flowing predominantly west, they meet near the city of Butte Falls. The main stem flows generally northwest until it empties into the Rogue Falls was incorporated in 1911, and remains the only incorporated town within the watershed's boundaries.
Union Creek is a 15-mile (24 km) long tributary of the Rogue River in the U.S. state of Oregon. Beginning west of Union Peak in the Cascade Range, it flows through the Rogue River – Siskiyou National Forest to meet the Rogue at Union Creek and the Union Creek Historic District.
Dead Indian Creek is a tributary of South Fork Little Butte Creek in Jackson County, in the U.S. state of Oregon. It flows generally north through the Rogue River – Siskiyou National Forest in the Cascade Range east of Medford. The creek begins at 2,562 feet (781 m) above sea level near Howard Prairie Lake and enters the South Fork at Camp Latgawa. The South Fork flows northwest to meet the North Fork near Lake Creek; combined they form Little Butte Creek, a tributary of the Rogue River.
Yonna is an unincorporated community in Klamath County, Oregon, United States. It lies east of Oregon Route 140 in Yonna Valley, northeast of Dairy and near the base of Short Lake Mountain.
Shevlin was an unincorporated community in Deschutes and Klamath counties in the U.S. state of Oregon. It consisted of a collection of logging camp buildings that were moved from place to place on rail cars as logging progressed. The loggers worked for the Shevlin–Hixson Company.
Gearhart Mountain is a 8,041-foot (2,451 m) high mountain in Lake County and Klamath County, Oregon, in the United States. It is located in the Gearhart Mountain Wilderness of the Fremont–Winema National Forest, northeast of the Sprague River valley and the town of Bly.
The Powell Buttes are mountains with several summits located in Crook County, Oregon, United States. The highest summit is over 5,200 feet (1,600 m). The mountains are geologically related to the Ochoco Mountains and are named after members of Joseph Powell's family.
