For the past two years, I have been surveying the eroding bluff of the coastal terrace between Mammoth Rocks and the Duncans Landing Rockshelter. Disclosure: These are links to Amazon. Their location at the back of the prairie, and along the ecotone separating the prairie and coastal range, almost guarantees that both rubbing rock sites were on a major trail corridor that led north and south along the interior edge of the coastal plain.

The Duncans Landing Rockshelter contains at least five cultural components, the next to the lowest (Component 2) dating to 9,000 CALYBP (Component 1 has yet to be dated). While resembling blades in the most generic sense (i.e., having parallel sides and a length more than twice that of the width), these flakes are not true blades and are easily distinguished from the true blades (or microblades) also found at the site. 1985:265-266).

However, they do allow a sense of the ecological dynamics of the Rancholabrean landscape. They would have also found the Duncans Landing Rockshelter located nearby. The Napa River Unit was first leveed off (diked) from . A small sample of soil was recovered from beneath Component 1, wet-washed using very fine mesh screen, and the screenings analyzed under a microscope by Rae Schwaderer, Thomas Wake, and me. As unlikely as it may seem, I believe the depression may be a relic wallow left over from the late Pleistocene. (11) It is likely that Paleoindians made use of the area as well.

Since 2003, archaeological excavations have been underway at Jasper Rock, a highly-polished jasper outcrop with evidence of past quarrying. Over time, plants and animals have adapted to the craters, and they are now a part of the local ecology. Proceedings of the American Philosophical Society 106(2):94-105.

Included among the artifacts are a few blade-like flakes with edge wear (Fig. The majority of the waste was derived from a core and flake industry. What are lacking, however, are blade cores. Thus, if my hypothesis is accurate, many of Californias vernal pools were born of abandoned wallows at the dawn of the Holocene. Advertisement More work is necessary in order to confirm their origin, as well as the existence of the two proposed Holocene-era microblade industries. Parkman, E. Breck, Timothy McKernan, Stephen Norwick, and Rolfe Ericksonn.d. 12 The Mammoth Rocks site likely commanded a similar position on the Rancholabrean landscape. 5 The deep excavation unit is sited immediately adjacent to the quarried boulder and in an area where large blocks of the outcrop were knocked or pried off (see Fig. 19 In 1993, I saw numerous buffalo rubbing rocks and wallows while assisting Dr. Jack Steinbring of the University of Winnipeg with a multi-province rock art assessment on the Canadian Plains. 3: Selected Artifacts from the southern North Coast Ranges. 2).
