Naturally, the most obvious corridor connecting the Franciscan Valley with the Farallon Plain followed the south side of the California River through the Golden Gate. After coming up from the Russian River by way of the pass, late Pleistocene animal herds would have looked out across an approximately 20-km wide coastal prairie (at ca. >9,000-<8,500 CALYRBP), a regional variant of the APT, extended as far south as Oregon (ibid:178).

Undivided Mesozoic volcanic and metavolcanic rocks. A grassland (or grassland savanna) of approximately 300,000 ha probably existed beneath the current San Francisco Bay and southward to San Juan Bautista. It is likely that plant adaptations and ecological dynamics mitigated against the in filling of many of the pools. Heizer, R.F., and H. Kelley1962Burins and Bladelets in the Cessac Collection from Santa Cruz Island, California. These microblades are primarily obsidian backed bladelets, perhaps found largely at sites proximal to the major obsidian sources at Napa Glass Mountain and Borax Lake.

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. There are also jasper, agates, jade and many other types of rock. (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 plants can adapt to bomb craters in Southeast Asia, they should have adapted similarly to abandoned wallows in California. Report prepared for the U.S. 19,000-15,000 CALYRBP), sea level was about 120 m lower than today, thus the exposed coastal plain extended all the way to or near the edge of the continental shelf, and included the Farallon Islands. 139-166.

They ranged from 30-90 mm in length and had retouch along one long side. If so, then it seems probable that some of Californias vernal pools began as animal wallows. 2). For example, African elephants wallow at waterholes in order to coat themselves in mud, then, as the mud dries, they rub it off against a hard object, often a large boulder. (11) It is likely that Paleoindians made use of the area as well. Mule Mountains Fire Agate. Rocks | Zero Waste Sonoma Dixon, E. James1999Bones, Boats, & Bison.

Over time, plants and animals have adapted to the craters, and they are now a part of the local ecology. This may be a reflection of the small sample size from the Sonoma Coast (n<10), but more likely these tools represents a different technology and purpose. We have 29 vendors who are excited to see you. That said, there are a number of archaeologists who have noted finding isolated blade-like flakes, microblades, and microblade cores without going so far as to propose a local microblade tradition (e.g., Beard 1979:75; Heizer 1953:264, 341; Miller 1988:22-23; Sampson 1983:129).

(5) Because the deep unit was sited directly beneath a heavily-polished knob of the outcrop, care must be taken to segregate possible geofacts and zoofacts from artifacts. The site is located just 4 km from the well known Borax Lake site (CA-LAK-36), at which were found Clovis-like fluted points and chipped crescents (Harrington 1948; Meighan and Haynes 1970).

SCSB-03-7: N, chalcedony end scraper. (13)To date, I have located at least three archaeological sites along the survey transect where artifacts eroding from the coastal bluffs (from the subsoil at depths of 50-150 cm) appear to suggest a considerable antiquity (> middle Holocene?). Swimming is absolutely banned at this beach due to the possible dangers of powerful sneaker waves and rip currents. Center for Archaeological Research at Davis. American Antiquity 44:55-69. Wrights Beach, the biggest sandy beach between the Russian River and Bodega Bay.

Boron Travertine - (6 collector specimens from same city, 7 collector specimens from nearby locations) Go forth and explore. In the case of those that did not, it seems likely that they served as useful waterholes in late spring and early summer, and would have thus been affected by the very presence of the megafauna (e.g., African elephants are known to enlarge and improve waterholes). However, in spite of this absence, I still believe that there is at least one unidentified cultural component lying below Component 1. As we excavated down, we discovered that the rock outcrop is polished to a depth of 2 m below the current ground surface. Hunting at Lake Sonoma - Support Lake Sonoma - Friends of Lake Sonoma
