Jordan Craters in SE Oregon is a field of well-preserved basaltic lava flows and scoria cones covering 250 sq km. The last eruption took place at Coffeepot Crater at the NW end of the lava field about 3200 years ago and produced a lava flow covering 75 square km and containing 1.6 km3 of olivine-bearing basaltic pahoehoe lava. The flows dammed local river valley, forming the two small Upper and Lower Cow Lakes at the SE end of the lava field.
Jordan Craters is known for its excellent exposures of a wide variety of lava flow features similar to Idaho's Snake River Plain to the east.
