Channel Islands Of California
The Channel Islands () are an eight-island archipelago located within the Southern California Bight in the Pacific Ocean, off the coast of California. The four Northern Channel Islands are part of the Transverse Ranges geologic province, and the four Southern Channel Islands are part of the Peninsular Ranges province. Five of the islands are within the Channel Islands National Park, and the waters surrounding these islands make up Channel Islands National Marine Sanctuary. The Nature Conservancy was instrumental in establishing the Channel Islands National Marine Sanctuary. The islands were inhabited as early as 13,000 years ago, the earliest paleontological evidence of humans in North America. They are the easternmost islands in the Pacific Island group. The Chumash and Tongva Native Americans who lived later on the islands may be the descendants of the original inhabitants, but they were then displaced by Spaniards who used the islands for fishing and agriculture.

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Arlington Springs Man
The Arlington Springs man is a set of Late Pleistocene human remains discovered in 1959 on Santa Rosa Island, one of the Channel Islands located off the coast of Southern California. The Arlington Springs archeological site is protected within northern Channel Islands National Park, and in Santa Barbara County. History Archaeology In 1959–1960, two femora were excavated by Phil C. Orr, curator of anthropology and paleontology at the Santa Barbara Museum of Natural History, at Arlington Springs on Santa Rosa Island. Orr believed the remains were those of a 10,000-year-old man and dubbed them the "Arlington Springs Man". The Arlington Springs Man was later re-examined in 1989 by Orr's successors at the museum, Dr. John R. Johnson and Don Morris. The two came to the initial assessment that the Arlington Springs Man was actually the "Arlington Springs Woman". Radiocarbon dating determined that the remains dated to 13,000 years BP, making the remains potentially the oldest-kno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Santa Rosae
Santa Rosae (also spelled Santarosae) was, before the end of the last ice age, an ancient landmass off the coast of present-day southern California, near Santa Barbara County and Ventura County, of which the northern Channel Islands of California are remnants. At its largest, Santa Rosae was roughly 3-4 times bigger than the northern Channel Islands of today, nearly 125 km (77.67 miles) long from east to west. Between about 20,000 and 5,000 years ago, Santa Rosae lost about 70% of its land mass to post-glacial rising sea level, leaving behind a vast submerged landscape currently being explored by scientists. San Miguel, Santa Rosa, Santa Cruz, and Anacapa Island comprise the unsubmerged portions of Santa Rosae today. This island was about 5 miles offshore. It broke up between about 11,000 and 9,000 years ago, and the present northern Channel Islands took their shape after the continental ice sheets melted and sea levels rose by about 100 meters.
