If correct, there would have been one large predator (e.g., sabertooth cat, California lion, dire wolf, American short face bear, etc.) The depression is encircled by four loci of polished rocks. The results of our investigation suggest that the polished rocks at both Mammoth Rocks and Jasper Rock were indeed created by Rancholabrean megafauna (Parkman et al. The chert flakes in the subsoil appear to have come from CA-SON-1713, a green chert source (with evidence of quarrying) located about 250 m north of Mammoth Rocks. CA-NAP-58, located just south of Calistoga in the northern Napa Valley, is my primary site for investigating this proposed technology (Fig. The sand is made up mostly of polished jasper and chert stones and ranges in size from fine gravel to coarse sand. The two main sites are referred to as Mammoth Rocks and Jasper Rock. Journal of California and Great Basin Anthropology 6(2):217-224. Harding Rock, the largest of the three, stood over 100 m in height. This undoubtedly attracted attention, and should have brought the areas earliest settlers to the site to investigate, regardless of whether they were hunters and gatherers moving west from the Great Basin, or maritime pioneers heading south along the coast. 3C, D, I) and one of obsidian (Fig. To access some of these places, you have . Unpublished manuscript in authors possession.

The area between Mammoth Rocks and the Duncans Landing Rockshelter was obviously the scene of concentrated megafaunal activity. (12) Indeed, providing the Coastal Migration Theory holds true, the corridor leading through the Alcatraz Triangle connecting the coastal plain with the interior could have provided the first settlers with an advantageous route for colonizing Californias Central Valley (Surovell 2003:589). If they want to take climbing to the great outdoors, we offer classes and clinics to teach them everything from tying proper knots to tackling El Capitan.'.

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. To the south, a late Holocene microblade industry was present in southern California, and is much better understood there (cf. While some of the Pleistocene pools have undoubtedly filled in over time, it is likely that many of these depressions have survived through the ages. There are also jasper, agates, jade and many other types of rock.

Ranch is open Thursday through Sunday for the B-Zone rifle deer season only. Archaeological Investigations at Jasper Rock. 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. Additionally, Dr. Christopher Chippendale of Cambridge University visited the Mammoth Rocks site as did a large tour group from the 2003 International Quaternary Association (INQUA) conference in Reno, led by Dr. Carol Prentice of the U.S. Geological Survey.Closer to home, Gary Shannon of California State Parks discovered a rubbing rock in the coastal range overlooking the Mammoth Rocks site.

Malki Museum Press. Marvin Rowe and Karen Steelman of the Department of Chemistry, Texas A&M University, have agreed to use their plasma-chemical extraction (PCE) method in an attempt to date samples of the polished rocks by direct AMS radiocarbon measurement (Rowe 2001; Rowe and Steelman 2002). My reasoning began with an observation at Mammoth Rocks in 2001. The climbing age range is vast. 3A, B). Jefferson, George T., and Judith L.

Rock hunting on Lake Michigan can be very satisfying as you may find agates, corals, quartz, or obsidian. Closer to home, several chipped stone crescents, thought to be associated with fluted points, have been recovered from this same ecotone on the Sonoma Coast (from sites at Bodega Head, Stillwater Cove, and Salt Point). Hammerstones and debitage also occur here, as do much larger (25-100 kg) detached blocks of the jasper outcrop (Fig. 2 Although the alternative explanations offered to explain the polished rocks have been all but ruled out, my rubbing rock interpretation still remains a working hypothesis and should not be considered a proven fact. This helps remove extoparasites from the animals skin. If Paleoindians populated the Sonoma Coast, it seems likely that they would have made great use of the interior edge of the coastal plain. In recent studies of the sea floor of the shelf, areas of relict sediment (deposits of mostly sand and gravel left on the shelf when it was exposed during times of lower sea level) have been mapped (Karl 2001:90). Dead Generation. A valid drivers license, hunting license and pig tag must be provided at the time of purchase. The spring and fall 2003, and spring 2004 archaeological field classes from Santa Rosa Junior College, under the direction of Thomas Origer, and a summer 2003 volunteer crew under my direction, have to date excavated approximately 30 cubic m of the site. New York: Grove Press. Brendan ONeil, an Associate Resource Ecologist with California State Parks, led me to the Jasper Rock site several weeks later. 2443 (24 October 1941), pp. 1. Monthly meetings offer a multimedia presentation and an opportunity to mix with local climbers, and are free to the general public. The discovery of the Sonoma Coast rubbing rocks has inspired a multidisplinary effort to better illuminate the natural and cultural histories that characterized the San Francisco Bay area at the end of the last Ice Age. The four loci surround an enigmatic wetland that I believe may represent a relic animal wallow.
