Near the Triangles center are found three rock pinnacles known as Harding, Shag, and Arch Rocks. If that is the case, then its presence helps explain the rubbing rocks that encircle it. By creating this paleoenvironmental model, the rubbing rocks become features of an integrated landscape rather than anomalous stand-alone sites. 18 The backed bladelets from Jasper Rock and Duncans Landing Rockshelter are unlike the typical microblades found on the Northwest Coast. These are all within San Mateo County, and are 10 minutes to half an hour away from each other. (8) The Mammoth Rocks site sits adjacent to one such corridor, the lower Russian River Valley. 89-107. Chariton River - Calcite & quartz crystals. Obsidian backed bladelets have also been reported from CA-NAP-1, the Goddard site (Heizer 1953:264, 341).

Such an area would have provided ideal cover for Ice Age predators (especially Smilodon californicus, Panthera leo, and Arctous simus) intent on ambushing passing prey animals. To date, the scientific testing of the model has been one of divergence. For the past two years, I have been surveying the eroding bluff of the coastal terrace between Mammoth Rocks and the Duncans Landing Rockshelter. The plots are spacious, and many are separated from one another, ensuring privacy. This has allowed me to regularly inspect the subsurface stratigraphy of a 5-km transect traversing the same area that I propose to have once been characterized by a major north-south game trail.

To date, I have located six sites consisting of one or more rubbing rocks, all within an area about 4 km in diameter. Not surprising, I have found a number of archaeological sites along this transect.One of the often voiced concerns with the Coastal Migration Theory, and with the Paleoindian occupation of the late Pleistocene coastline, is that the archaeological sites associated with such use were inundated by the rising ocean at the close of the last Ice Age, and thus little can be found of them.
