Jordan Craters volcanic field consists of well-preserved basaltic lava flows and scoria cones that are the youngest and northernmost of a group of three Quaternary lava fields covering an area of 97 sq mi (250 sq km) in SE Oregon. The Pleistocene 4,833 feet (1473m) high Clarks Butte shield volcano and Rocky Butte (Lava Butte) lava fields lie to the south, along the trend of regional Basin and Range faulting. Jordan Craters lie on the Owyhee-Oregon plateau at the SE end of a series of widely scattered young volcanic fields extending SE from Bend, Oregon.
Coffeepot Crater at the NW end of the lava field was the source about 3200 years ago of one of Oregon's youngest lava flows, which covered 29 sq mi (75 sq km) with 2,092 cu yds (1.6 cu km) of olivine-basaltic lava having a smooth or billowy surface. The flows dammed local drainages, forming the two small lakes at the SE end of the lava field. Jordan Craters is renowned for its excellent exposures of a wide variety of youthful lava-flow features and has similarities to Holocene basaltic flows of Idaho's Snake River Plain to the east.
