La Brea Tar Pits
La Brea Tar Pits comprise an active Paleontological site, paleontological research site in urban Los Angeles. Hancock Park was formed around a group of tar pits where natural Bitumen, asphalt (also called asphaltum, bitumen, or pitch; ''brea'' in Spanish) has seeped up from the ground for tens of thousands of years. Over many centuries, the bones of trapped animals have been preserved. The George C. Page Museum is dedicated to researching the tar pits and displaying specimens from the animals that died there. "La Brea Tar Pits" is a registered National Natural Landmark. Formation Tar pits are composed of Heavy crude oil, heavy oil fractions, called gilsonite, which seep from the earth as oil. Crude oil seeps up along the 6th Street Fault from the Salt Lake Oil Field, which underlies much of the Fairfax District north of Hancock Park. The oil reaches the surface and forms pools, becoming asphalt as the lighter fractions of the petroleum biodegrade or evaporate. The asphalt the ...

Microfossil
A microfossil is a fossil that is generally between 0.001 mm and 1 mm in size, the visual study of which requires the use of light or electron microscopy. A fossil which can be studied with the naked eye or low-powered magnification, such as a hand lens, is referred to as a macrofossil. Microfossils are a common feature of the geological record, from the Precambrian to the Holocene. They are most common in deposits of marine environments, but also occur in brackish water, fresh water and terrestrial sedimentary deposits. While every kingdom of life is represented in the microfossil record, the most abundant forms are protist skeletons or microbial cysts from the Chrysophyta, Pyrrhophyta, Sarcodina, acritarchs and chitinozoans, together with pollen and spores from the vascular plants. Overview A microfossil is a descriptive term applied to fossilized plants and animals whose size is just at or below the level at which the fossil can be analyzed by the naked e ...

Portolá Expedition
thumbnail, 250px, Point of San Francisco Bay Discovery The Portolá expedition was a Spanish voyage of exploration in 1769–1770 that was the first recorded European exploration of the interior of the present-day California. It was led by Gaspar de Portolá, governor of '' Las Californias'', the Spanish colonial province that included California, Baja California, and other parts of present-day Mexico and the United States. The expedition led to the founding of Alta California and contributed to the solidification of Spanish territorial claims in the disputed and unexplored regions along the Pacific coast of North America. Background Although already inhabited by Native Americans, the territory that is now California was claimed by the Spanish Empire in 1542 by right of discovery when Juan Rodríguez Cabrillo explored the Pacific coast. Cabrillo's exploration laid claim to the coastline as far north as forty-two degrees north latitude. This northern limit was later confirmed ...

Channel Islands (California)
The Channel Islands () are an eight-island archipelago located within the Southern California Bight in the Pacific Ocean, off the coast of California. They define the Santa Barbara Channel between the islands and the California mainland. 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. 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. There is evidence that humans have lived on the Northen Channel Islands for thousands of years. Radiocarbon dating shows that there was a continuous human presence between 8000-11000 years ago. The islands were inhabited primarily by two different Native American groups, the Chumash, and the Tongva/Gabrieleno .The Chan ...

Santa Barbara Channel
The Santa Barbara Channel is a portion of the Southern California Bight and separates the mainland of California from the northern Channel Islands. It is generally south of the city of Santa Barbara, and west of the Oxnard Plain in Ventura County. It trends east–west, is approximately long and averages about across, becoming narrowest at its easternmost extremity where Anacapa Island is about from the mainland. During the last ice age, the four northern Channel Islands, including Santa Rosa Island, were conjoined into Santa Rosae, a single island that was only five miles (8 km) off the coast. The islands are visible from the mainland on clear days. Excursion boats cross the channel, taking visitors to watch whales and visit the islands. In the perpendicular (east-west) direction, huge cargo ships and tankers occupy a major shipping lane on their way to or from the ports of Los Angeles and Long Beach. The Channel is the location of numerous oil fields, some of w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
California Redwood
''Sequoia sempervirens'' ()''Sunset Western Garden Book,'' 1995: 606–607 is the sole living species of the genus '' Sequoia'' in the cypress family Cupressaceae (formerly treated in Taxodiaceae). Common names include coast redwood, coastal redwood and California redwood. It is an evergreen, long-lived, monoecious tree living 1,200–2,200 years or more. This species includes the tallest living trees on Earth, reaching up to in height (without the roots) and up to in diameter at breast height. These trees are also among the longest-living trees on Earth. Before commercial logging and clearing began by the 1850s, this massive tree occurred naturally in an estimated along much of coastal California (excluding southern California where rainfall is not sufficient) and the southwestern corner of coastal Oregon within the United States. Being the tallest tree species, with a small range and an extremely long lifespan, many redwoods are preserved in various state and nationa ...

Tomol
A ''tomol'' or ''tomolo'' (Chumash) or ''te'aat'' or ''ti'at'' (Tongva/Kizh) are plank-built boats, historically and currently in the Santa Barbara, California and Los Angeles area. They replaced or supplemented tule reed boats. The boats were between in length and in width. The Chumash refer to the ''tomol'' as the "House of the Sea" for their reliability. Double-bladed kayak-like paddles are used to propel the boat through the ocean. Some sources suggest the boats may have origins at Santa Catalina Island (California), Catalina Island and have been in use for thousands of years. Others suggest an origin on the Northern Channel Islands during the first millennium CE. The ''tomol'' has been described as "the single most technologically complex watercraft built in North America" and as being unique to "the New World." The boats are still constructed by Chumash, Tongva/Kizh, and Acjachemen people today. Construction ''Tomols'' were preferably built out of redwood that had drift ...
