A karrenfeld is a limestone surface with wide fissures (karren) dissolved into it. Karrenfelds are typical of karst landscapes, where solution is the dominant means of erosion. A large karrenfeld underlies the town of Columbia, in the California gold country, and a neighboring area across the canyon of the Stanislaus River near Vallecito. Take a look at this distinctive geological feature and learn its significance in American history.
