Composite overhead photograph of 10-x20’ strip across the main excavation block at the Sleeper site showing the rock layer and one circular cooking hearth (far right). The form of the hearth (Feature 9) is well preserved in contrast to the more scattered rocks elsewhere. This patterning is typical of many campsites on the Edwards Plateau—repeated cooking with hot rocks left behind lots of scattered debris and dismantled features. TARL archives.
