As a result, new facilities were scheduled to be constructed in Lower Camp. The Lower Camp site consists of an oval scatter of prehistoric and historic artifacts. One of these small tests, however, revealed an intact deposit of cultural materials-the remnants of a prehistoric occupation in Lower Camp. Traces of two hearths, seen as ash stains mixed with land crab claws and other food remains, were also discovered. In all, over 2,000 ceramic fragments and nearly 9,000 items of food remains, such as crab claws and fish bones, were recovered.
Some coral fragments appear to have been used as grinding instruments.
The site yielded an abundance of well-made but mostly undecorated ceramic vessel fragments. The vessels include at least ten different forms. By comparing artifacts found at the bottom of an excavation with those near the top, archeologists can study changes in ceramic forms through time. Few changes were noted in the ceramic assemblage from Lower Camp, suggesting that the occupation did not last long, perhaps 100 to 200 years. The Lower Camp site lies between two mangrove stands, close to the Ensenada Honda Bay.
