The flows of Jordan Craters volcanic field are the youngest of a large Quaternary basalt fields in the eastern part of the U.S. state of Oregon. The most recent flows come from Coffeepot Crater, a large breached cinder cone. These flows show excellent examples of inflated lava.[4]

Jordan Craters is approximately 200 kilometres (120 mi) southwest of Boise, Idaho.[2]

The craters are free and open to the public all year.
