The Pitch Lake is the largest natural deposit of bitumen in the world, estimated to contain 10 million tons. It is located in La Brea in southwest Trinidad , within the Siparia Regional Corporation . The lake covers about 0.405 square kilometres (100 acres) and is reported to be 76.2 metres (250 feet) deep.
56-411: Pitch Lake is a popular tourist attraction , including a small museum, from where official tour guides can escort people across the lake. The lake is mined for asphalt by Lake Asphalt of Trinidad and Tobago . The Pitch Lake has fascinated explorers and scientists, attracting tourists since its re-discovery by Sir Walter Raleigh in his expedition there in 1595 . Raleigh himself found immediate use for
112-469: A dead animal sank, the asphalt would soak into them, turning them dark-brown or black in color. Lighter fractions of petroleum evaporated from the asphalt, leaving a more solid substance, which then encased the bones. Dramatic fossils of large mammals have been extricated, but the asphalt also preserves microfossils : wood and plant remnants, rodent bones, insects, mollusks, dust, seeds, leaves, and pollen grains. Examples of some of these are on display in
168-571: A group of Spanish explorers led by Gaspar de Portolá , made the first written record of the tar pits in 1769. Father Juan Crespí wrote, While crossing the basin, the scouts reported having seen some geysers of tar issuing from the ground like springs; it boils up molten, and the water runs to one side and the tar to the other. The scouts reported that they had come across many of these springs and had seen large swamps of them, enough, they said, to caulk many vessels. We were not so lucky ourselves as to see these tar geysers, much though we wished it; as it
224-454: A hypothesized "carnivore trap" in which large herbivores entrapped in asphalt attracted predators and scavengers which then became entrapped while trying to steal a quick meal. However, new research with an eye towards microfossils has revealed a stunning diversity and abundance of many types of mammals. According to paleontologist Thomas Halliday, "Rancho La Brea Tar Pits... where big herbivores typically get stuck in tar which naturally seeps from

These fossils were packaged in boxes at the construction site and moved to a compound behind Pit 91, on Page Museum property, so that construction could continue. Twenty-three large accumulations of tar and specimens were taken to
784-659: Is a registered National Natural Landmark . Tar pits are composed of heavy oil fractions called gilsonite , which seeps 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 then normally hardens into stubby mounds. The pools and mounds can be seen in several areas of

According to Woodside, "host muds and/or shales become over pressured and under compacted in relation to the surrounding sediments...mud or shale diapirs or mud volcanoes result because of the unstable semi-fluid nature of
1288-556: The University of California, Berkeley led much of the original work in this area early in the 20th century. Contemporary excavations of the bones started in 1913–1915. In the 1940s and 1950s, public excitement was generated by the preparation of previously recovered large mammal bones. A subsequent study demonstrated the fossil vertebrate material was well preserved, with little evidence of bacterial degradation of bone protein. They are believed to be some 10–20,000 years old, dating from
1344-520: The state fossil of California, the saber-toothed cat ( Smilodon fatalis ). Contrary to popular belief, the tar pits don't contain dinosaur remains, as these were extinct before the pits formed. The park is known for producing myriad mammal fossils dating from the Wisconsin glaciation . While mammal fossils generate significant interest, other fossils including fossilized insects and plants, and even pollen grains, are also valued. These fossils help define
1400-621: The George C. Page Museum. Radiometric dating of preserved wood and bones has given an age of 38,000 years for the oldest known material from the La Brea seeps. The Chumash and Tongva people used tar from the pits to build plank boats by sealing planks of California redwood trunks and pieces of driftwood from the Santa Barbara Channel , which they used to navigate the California coastline and Channel Islands . The Portolá expedition ,

The ultimate primary purpose of attractions is to attract the customer's attention so that they can come to a specific location and explore the various attractions on vacation. In the travel and tourism industry, attractions therefore play a particularly important role as this attracts tourists from all over the world. Tourist attractions are also created to capitalize on legends such as
2072-563: The event of war, many tourist attractions are a special goal in order to cause lasting damage to the enemy or to finance the war. International attempts are therefore made to protect and preserve these economic and cultural foundations of a community, city or country. There is intensive cooperation between the United Nations , UNESCO and Blue Shield International on the protection of cultural goods and UNESCO World Heritage Sites. However, cooperation between organizations and state authorities

You get a herbivorous sample of the ecosystem and very few carnivores, except those that are trying to scavenge on the already dead carcasses that have just got stuck in the tar." Methane gas escapes from the tar pits, causing bubbles that make the asphalt appear to boil. Asphalt and methane appear under surrounding buildings and require special operations for removal to prevent

The museum is featured prominently in the 1992 cult classic film Encino Man , where the title character recollects he was previously a caveman during his exploration of the museum's exhibits. In respect of it being the "richest paleontological site on Earth for terrestrial fossils of late Quaternary age,"
2520-407: The park. This seepage has been happening for tens of thousands of years, during which the asphalt sometimes formed a deposit thick enough to trap animals. The deposit would become covered over with water, dust, or leaves. Animals would wander in, become trapped, and die. Predators would enter to eat the trapped animals and would also become stuck, a phenomenon called a predator trap . As the bones of
2576-611: The pitch. In the 1840s, Abraham Pineo Gesner first obtained kerosene from a sample of Pitch Lake bitumen . In 1887, Amzi Barber , an American businessman known as "The Asphalt King", secured a 42-year monopoly concession from the British Government for the Pitch Lake for his company, Barber Asphalt Paving Company . It was from this source that many of the first asphalt roads of New York City, Washington D.C., and other Eastern U.S. cities were paved. The origin of The Pitch Lake
2632-516: The primary motivations for a region to promote itself as a tourism destination is the expected economic benefit. According to the World Tourism Organization , 698 million people travelled to a foreign country in 2000, spending more than US$ 478 billion. International tourism receipts combined with passenger transport currently total more than US$ 575 billion – making tourism the world's number one export earner. Tourist attractions can: In
