The flows of Jordan Craters volcanic field are the youngest of a series of large Quaternary basalt fields in the eastern part of the U.S. state of Oregon.
The field is thought to be approximately 3200 years old, based on findings of a lake sediment coring experiment in 1986.
[4] The most recent flows come from Coffeepot Crater, a large breached cinder cone.
[4] Jordan Craters is approximately 120 miles (200 km) southwest of Boise, Idaho[3] and 18 miles (30 km) northwest of Jordan Valley, Oregon.
