Details

Identifiernot specifiedPhotographerRalph HawkinsDescriptionA rock hole with diversion grooves and a grinding groove on the upstream side. Rock holes were regularly kept clean and filled with water after rain. To prevent seepage containing mud and leaves from polluting the water a diversion groove was engraved on the upstream side to divert the muddy water away from the fresh water in the rock hole.
