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.
Rocky Butte (previously known as Mowich Illahee [4] and Wiberg 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.

Wizard Island is a volcanic cinder cone which forms an island at the west end of Crater Lake in Crater Lake National Park, Oregon.The top of the island reaches 6,933 feet (2,113 m) above sea level, about 755 feet (230 m) above the average surface of the lake.
Pilot Butte is a Pleistocene cinder cone volcano. [5] [6] It lies just outside the southeastern margin of the Crooked River caldera, [7] which collapsed and formed volcanic fields of rhyolitic lava flows, lava domes, and dikes [8] including Powell Buttes, Gray Butte, Grizzly Mountain, and Barnes Butte.

The Catlin Gabel tubes lie among cinder cones and lava flows from the Pliocene to Pleistocene, and they are the oldest known lava tubes in Oregon, older than the Holocene. [83] The tubes were produced by a small vent at the southern end of the northern segment of the field, [ 84 ] extending 2.5 miles (4.0 km) from its base to the south and then ...
Powell Butte is a cinder cone butte [4] and is part of the Plio-Pleistocene Boring Lava Field, [4] a group of volcanic cones that got their name from the low, forested Boring Hills formation. [5] Located in the Portland Basin, the Boring Lava Field consists of monogenetic volcanic cones that appear as hills throughout the area, reaching heights ...
Sand Mountain marks the largest cinder cone in the field, at a height of 820 feet (250 m). [1] According to the Global Volcanism Program, the field includes six major clusters of volcanic vents, all pyroclastic cones. These are the Central Group, Little Nash Crater, Lost Lake Group, Nash Crater, Sand Mountain Cones, and South Group. [11]
