Bill Davis pauses while recording an unusual open site (VV6) consisting mainly of 10 bedrock mortar holes along a limestone ledge overlooking California Creek, a tributary of Castle Canyon. Wooden pestles, several of which have been found in dry caves, were used in combination with bedrock mortars to pulverize seeds and nuts. (The creek had probably been damned up to create a livestock watering hole.) Photo from ANRA-NPS Archives at TARL.
