Abstract
Competing models describe the land-use of Coastal San Diego County during the Late Holocene. The Coastal Decline Model contends that coastal resources were utilized sparingly during the Late Holocene, concurrent with ecological changes resulting in the silting of many of the local lagoon environments. An intensified use of interior resources, including semipermanent habitations, is thought to have accompanied the decline of coastal utilization. Conversely, the Coastal Intensification Model states that the San Diego Coastal environs were heavily exploited during the Late Holocene, with semi-permanent residences located in coastal contexts. This study attempts to use the analysis of flaked stone artifacts from two groups of sites in Northern San Diego County, San Elijo Lagoon and Las Pulgas Corridor, to test the validity of the Coastal Decline Model. Various methods, including the diversity and density of lithic artifacts, the change and continuity in lithic artifacts through time, and the ratios of cores to bifaces, are employed in the lithic analysis. The results of the lithic analysis appear to support the model of coastal decline in Northern San Diego County during the Late Holocene. However, the results also indicate a continuous use of coastal resources through time, though probably in lesser frequencies and for different purposes during the Late Holocene as opposed to the Early and Middle Holocene.
