Testing of prehistoric sites in the Farm Drop Zone on Edwards Air Force Base focused on questions of site function, particularly the potential role of these sites in the regional settlement system. Large villages fitting the "Desert Village" pattern had been identified in the Antelope Valley, and previous research at the Farm Drop Zone sites suggested that they might also fit the pattern. Evidence from the testing indicates that the sites resulted from repeated low-intensity uses of the area over a long period of time, rather than from a village occupation. The implications of these findings are discussed.
