Abstract
  • The portion of the Oregon coast extending from Cape Blanco south into California has long been recognized as a distinct physiographic region, with probable ramifications for prehistoric subsistence and settlement patterns. Several researchers have proposed models outlining a greater reliance upon marine/littoral resources among groups within this region, while more northerly groups exhibited a higher reliance upon estuarine resources. Current knowledge about regional prehistoric subsistence practices, based upon the archaeological record and ethnographic sources, was correlated with the distribution and relative abundance of exploited and potentially exploitable marine species. These data suggest that the abundant coastal rocks and islands found along this section of the Oregon coast serve to concentrate diverse and abundant animal resources within a confined area, allowing for ease of exploitation. Therefore, the rocks and islands were of potential economic importance to aboriginal groups. To support this hypothesis archaeological subsurface testing was undertaken on the only previously recorded offshore island site, and an archaeological sample survey was conducted on additional rocks and islands along this section of coastline to determine their utilization by native peoples. Two additional prehistoric sites were recorded. The results of these investigations are herein presented, and directions for future research are discussed.
