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 Boring Lava Field (also known as the Boring Volcanic Field) [3] 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.

J.E. Allen, an emeritus professor of Geology at Portland State University, listed its elevation as 560 feet (170 m) in a 1975 publication. [3] 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]
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 114.22-acre (46.22-hectare) Pilot Butte State Scenic Viewpoint, presented as a gift to the State of Oregon in 1928, is a Bend icon. Pilot Butte itself ...
Chief among these were cinder cones. Although the early examples are gone—cinder cones erode easily—there are at least 13 much younger cinder cones in the park, and at least another 11 or so outside its borders, that still retain their distinctive cinder cone appearance.
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.
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]
