Four Craters Lava Bed
Wilderness Study Area - Oregon
The Four Craters Lava Bed Wilderness Study Area (WSA) is located in Lake County, Oregon, approximately 60 miles southeast of Bend, Oregon and 8 miles north of the small town of Christmas Valley. The WSA is divided into two distinctive types of land areas. The first type is the rugged lava flows and cinder cones. The second type is sagebrush/grassland flats. The WSA contains the "Crack in the Ground," a large tension fracture in the basalt approximately 2 miles long and from 10 to 30 feet in depth. This crack reaches a maximum width of about 20 feet. Another tension fracture, volcanic spires and pressure ridges also occur in the lava flow.
