Continental flood basalt province in the Western United States
The Columbia River Basalt Group (including the Steen and Picture Gorge basalts) extends over portions of four states.
The Columbia River Basalt Group (CRBG) is the youngest, smallest and one of the best-preserved continental flood basalt provinces on Earth, covering over 210,000 km2 (81,000 sq mi) mainly eastern Oregon and Washington, western Idaho, and part of northern Nevada.[1] The basalt group includes the Steens and Picture Gorge basalt formations.
