A stone stripe, also called a lava stringer, is an elongated concentration of mostly talus-like basalt rock found along a hillside or the base of a cliff. Many stone stripes occur without cliffs. A stone stripe is identified by its lack of vegetative cover. They typically occur in north central Oregon and develop at 900 to 1,100 meter elevations. Lengths can range from only a few meters to over 150 meters, and widths measure from .3 to 3 meters. Depths of the stone stripes range from 20-65 centimeters.
