Early/Middle Period Subsistence Changes at SBA-1, Rincon Point, California


In general terms the changes at SBA-1 appear to reflect a broadening of the resource base, with fish and shellfish making up a greater share of the protein captured in the later period. This is in general agreement with the patterns predicted by regional theories dealing with environmental change and population growth in the Santa Barbara Channel region (Glassow 1980a: 14). Archaeological data (Glassow, Wilcoxon, and Erlandson n.d.) suggest that populations in the channel region were increasing during the periods in question. Such an increase in the number of people utilizing the region's resources would be likely to produce an intensification in the use of the marine environment as a result of the limitations on the terrestrial resources in the narrow coastal zone. The data from SBA-1 appear to show the effects of such intensification.
