La Jolla Complex
The archaeological La Jolla complex (Shell Midden People, Encinitas Tradition, Millingstone Horizon) represents a prehistoric culture oriented toward coastal resources that prevailed during the middle Holocene period between c. 8000 BC and AD 500 in southwestern California and northwestern Baja California. Description Characteristics of the La Jolla complex include handstones and basin or slab millingstones ( manos and metates), rough percussion-flaked stone edge tools, flexed burials, and extensive exploitation of shellfish, particularly venus clam (''Chione'' spp.), scallop (''Argopecten aequisulcatus''), mussel (''Mytilus californianus''), and oyster (''Ostrea lurida''). Cogged stones and discoidals are distinctive but unusual artifacts. Other uncommon artifacts include shell ornaments (primarily spire-removed ''Olivella'' spp. beads) and projectile points (Pinto, Gypsum, and Elko forms). Bones from sea mammals and fish occur in La Jollan middens, but they are not abundant. Fis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holocene
The Holocene ( ) is the current geological epoch. It began approximately 11,650 cal years Before Present (), after the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch, called the Flandrian interglacial.Oxford University Press – Why Geography Matters: More Than Ever (book) – "Holocene Humanity" section https://books.google.com/books?id=7P0_sWIcBNsC The Holocene corresponds with the rapid proliferation, growth and impacts of the human species worldwide, including all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban living in the present. The human impact on modern-era Earth and its ecosystems may be considered of global si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cynthia Irwin-Williams
Cynthia Irwin-Williams (April 14, 1936 – June 15, 1990) was an archaeologist of the prehistoric American Southwest. She received a B.A. in Anthropology from Radcliffe College in 1957; the next year she received a M.A. in the same field. In 1963 she completed her educational career in Anthropology with a PhD. from Harvard University. Beginning her career in the 1950s, Irwin-Williams was considered a groundbreaker for women in archaeology, like her friend and supporter Hannah Marie Wormington.Cassells, E. Steve. (1997). ''The Archaeology of Colorado, Revised Edition.'' Boulder, Colorado: Johnson Books. pp. 298-299. . Archaeological career She worked with her brother, Henry Irwin, a fellow archaeologist, in Colorado from the mid-1950s to 1960. In 1966 Irwin-Williams and her brother published a book of her findings from the Magic Mountain site excavation performed for the Peabody Museum of Harvard University in 1959–1960. They also worked on the nearby and related LoDaisKa sit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

History Of San Diego
The written (as opposed to oral) history of the San Diego, California, region began in the present state of California when Europeans first began inhabiting the San Diego Bay region. As the first area of California in which Europeans settled, San Diego has been described as "the birthplace of California." Explorer Juan Rodriguez Cabrillo claims to have discovered San Diego Bay in 1542, roughly 200 years before other Europeans settled the area; in truth, Native Americans such as the Kumeyaay people had been living in the area for as long as 12,000 years prior to any European presence. A fort and mission were established in 1769, which gradually expanded into a settlement under first Spanish and then Mexican rule. San Diego officially became part of the U.S. in 1848, and the town was named the county seat of San Diego County when California was granted statehood in 1850. It remained a very small town for several decades, but grew rapidly after 1880 due to development and the e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archaeological Sites In Baja California
Archaeology or archeology is the scientific study of human activity through the recovery and analysis of material culture. The archaeological record consists of artifacts, architecture, biofacts or ecofacts, sites, and cultural landscapes. Archaeology can be considered both a social science and a branch of the humanities. It is usually considered an independent academic discipline, but may also be classified as part of anthropology (in North America – the four-field approach), history or geography. Archaeologists study human prehistory and history, from the development of the first stone tools at Lomekwi in East Africa 3.3 million years ago up until recent decades. Archaeology is distinct from palaeontology, which is the study of fossil remains. Archaeology is particularly important for learning about prehistoric societies, for which, by definition, there are no written records. Prehistory includes over 99% of the human past, from the Paleolithic until the advent of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
