During the summer and fall of 2003, one of the units was expanded into a 4x4 m block exposure (Fig. Wiley Wells Agate Nodules and Geodes. That means reconstructing major game trails, calculating optimal carrying capacities, estimating numeric predator-prey relationships, and integrating interrelated plant and animal communities, among other things. Heizer, Robert F.1953 Archaeology of the Napa Region, University of California Anthropological Records 12(6).

However, much more work is necessary to confirm or deny my observations. It is likely that plant adaptations and ecological dynamics mitigated against the in filling of many of the pools. 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. The tremendous amount of obsidian waste material littering the sites surface suggests that it served as a workshop. In spring 2003, six 1x1 m units were excavated near the jasper outcrop. To date, all work conducted at CA-NAP-58 has consisted of surface survey.
Rocks | Zero Waste Sonoma As we excavated down, we discovered that the rock outcrop is polished to a depth of 2 m below the current ground surface. 9 The rocks are located at approximately 37 50 N, 122 27 W. 10 Because these three pinnacles were perceived to be potential navigational hazards, the United State Geological Survey developed plans to remove the upper portions of each rock and place the debris in nearby bayfloor depressions (Chin et al.

However, they do allow a sense of the ecological dynamics of the Rancholabrean landscape. However, they are more likely associated with the proposed middle-late Holocene technology. To access some of these places, you have . Further inland, an approximately 200,000-ha grassland (or grassland savanna) extended from the California River north to Cloverdale, including the Petaluma and Sonoma Valleys and the Santa Rosa Plain.

If so, then it seems probable that some of Californias vernal pools began as animal wallows. food revolution network credibility. During earlier times, these features in the Central Valley were often referred to perhaps derisively as hogwallows just as similar features were referred to as buffalo wallows on the Great Plains (Anonymous 1998:15). Quaternary Research. In: Handbook of Rock Art Research, David S. Whitley, ed., pp. Check out our page onSustainable Travel, and look over theLeave No Trace Seven Principles.

Pinus radiata and P. muricata predominated at that time. 2002bMammoth Rocks: Where Pleistocene Giants Got a Good Rub? 390-391. During summer 2003, I worked with a team of researchers at Sonoma State University to analyze samples of the polished rock using both a Scanning Electron Microscope (SEM) and an Atomic Force Microscope (AFM). Furthermore, my calculations suggest that in the most optimum conditions, there may have been one megaherbivore per 4 ha. Entry permits and/or passes or special drawing may be required for hunting on some Type C wildlife areas.

Ikeda and Robert A Schlising, eds., pp. . However, upon the demise of the megafauna, and for the past ten millennia, the plants would have been free to move in and colonize the abandoned wallows. Science 167(3922):1213-1221. Near Indian Head Hill in San Diego County is a deposit of fine-quality hessonite garnet, and another deposit is near Dos Cabezas. Fremontia 27(4) and 28(1):28-37. Since 2003, archaeological excavations have been underway at Jasper Rock, a highly-polished jasper outcrop with evidence of past quarrying. In Sonoma County, some of the best stops for sea stacks are at SON 22.20, SON 24.42, and finally at the PG&E marker 45.35 at Salt Point State Park. Serpentinite is closely connected with good quality metamorphic rocks, and it may work to transport blueschist and eclogite blocks from deep inside the subduction zone into the mlange. They would have also found the Duncans Landing Rockshelter located nearby. (1) These are features that I believe were used for grooming by now-extinct Ice Age megafauna such as Mammuthus columbi and Bison antiquus. SCSB-03-2: L, quartz thumbnail scraper; M, chalcedony side scraper (has polish on edge at bottom of image).

Similar findings were made at the Big Eddy site in Missouri, where lithics thought to be pre-Clovis in origin, are now thought to be zoofacts (Lopinot et al. 1. In the lab, SEM and AFM analyses have resulted in evidence that appears to validate the rubbing rock interpretation. New York: Altamira. Either way, things are learned in the process. Over the past two years, I have developed what I term, The Rancholabrean Hypothesis. Simply put, the hypothesis proposes that elements of the Rancholabrean landscape (e.g., megamamal rubbing rocks and wallows) still survive and can be detected on the contemporary landscape. ); F, quartz blade-like flake (?

Andesite and rhyolite flow rocks, greenstone, volcanic breccia and other pyroclastic rocks; in part strongly metamorphosed. The projectile points and obsidian hydration indicate a date of about 500CALYBP for the upper component (0-90 cm). However, some of the mechanically-produced zoofacts appear to closely resemble cultural debitage. But also reported as possibly open with permission and that adjacent,unposted,exposures are accessible. I believe that is only partly true. Obsidian backed bladelets have also been reported from CA-NAP-1, the Goddard site (Heizer 1953:264, 341). Here are the first five locations. 2716 (17 January 1947), p. 65. The results of that experiment are currently being analyzed.

Erlandson, Jon M., Theodore G. Cooley, and Richard Carrico1987A Fluted Projectile Point Fragment from the Southern California Coast: Chronology and Context at CA-SBa-1951. Simons, Dwight D., Thomas N. Layton, and Ruthann Knudson1985A Fluted Point from the Mendocino County Coast, California. 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). 13 The preliminary analysis of fossil conifers from Bodega Head indicates that the coastal prairie was bordered by a closed-cone coniferous forest at approximately 50,000 CALYRBP, during the time of the Port Talbot Interstadial. The Franciscan Intricates complex structure and materials lay out like a buffet for eager geologists. Monthly meetings offer a multimedia presentation and an opportunity to mix with local climbers, and are free to the general public. 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. 89-107. They do not appear to have been made for fitting into slots in bone tools. 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.
