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.
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 ...

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.
The Western Cascades or Old Cascades are a sub-province of the Cascade Range in the U.S. state of Oregon, between the Willamette Valley and the High Cascades. [1] The Western Cascades contain many extinct shield volcanoes, cinder cones and lava flows, and the region is highly eroded and heavily forested.
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 Mount Washington Wilderness includes a number of cinder cones, typically with elevations between 150 and 300 feet (46 and 91 m). Composed of gray to red cinder, they also have scoria and welded spatter. [24] Major cinder cones in the wilderness include Belknap Crater, Twin Craters, Scott Mountain, and the Sand Mountain craters. [25]
The Sand Mountain Volcanic Field includes 23 basalt and basaltic andesite cinder cones and associated lava flows, [5] which were produced by two roughly north–south trending [23] alignments of 42 volcanic vents. [5] The two groups cross near the Sand Mountain cinder cone; their alignments imply the existence of complex volcanic dikes under ...
