Chalk Bluff, for which the road is named for, is remarkably a straight, ~5-mile-long, escarpment that forms the south edge of the Volcanic Tableland. Named Chalk Bluff for its light tan-to-white colored, chalk-like rocks, they stand in contrast to the darker, volcanic Bishop tuff boulders that stand atop the escarpment and are popular with rock climbers. The Owens River flows below the Chalk Bluff with the gravel road running between, all making for a truly unique riding experience.
