Some of the most peculiar lakes in the world are comprised of asphalt, often known as bitumen, the same substance used to pave highways.
California is among the states with the most extensive asphalt lakes.
bitumen asphalt lakes
Although the great majority of asphalt used today is produced from petroleum, asphalt can also be found in nature in concentrated form.
They can seep through the ground and form large puddles known as asphalt lakes or tar pits.
Occasionally, they are found saturated in sands, such as the Athabasca oil sands in northeastern Alberta, Canada, which are the largest natural bitumen deposit on the planet.
Asphalt is also known to erupt from rare underwater volcanoes, which were just discovered in 2003.
Only a few large asphalt lakes are known to exist throughout the world.
The largest of these is Pitch Lake, which is located near the southwest Trinidad hamlet of La Brea.
natural bitumen lakes
Asphalt lakes, sometimes known as pitch lakes, are tar pits generated when bitumen, a type of petroleum, is forced to the surface of the Earth.
The bitumen collects at the surface, and the lighter elements evaporate, forming a natural asphalt pool.
This occurs most frequently near fault lines.
The vast majority of asphalt produced worldwide is obtained from industrial petroleum; but, natural sources also contribute to the total.
It is predicted that 70 percent of all asphalt will be utilized for road construction.
Pitch Lake receives tens of thousands of tons of pitches each year.
In 1867, asphalt was first extracted from the lake by Lake Asphalt of Trinidad and Tobago, a state-owned firm that continues to operate today.
It is estimated that the overall asphalt reserves in Pitch Lake amount to 6 million tons, although they are constantly replenished by oil from below.
Over time, these deposits transform into asphalt also known as bitumen or pitch, which can be used for road construction.
natural bitumen asphalt lake
Pitch lake is a huge surface deposit of natural asphalt and heavy oils remaining after the lighter, more volatile components of a crude oil seepage dissipate.
Occasionally, Pitch Lake is referred to as a natural asphalt lake.
The Guanaco Lake in Venezuela, also known as Bermudez Lake, is one such place.
This lake is reported to contain 6,000,000 tons of asphalt and has a surface area of over 445 hectares (1,100 acres).
Between 1891 and 1935, it was the commercial industry's principal source of asphalt.
The tar pits at Rancho La Brea in Los Angeles are an excellent example of the widespread occurrence of smaller deposits in regions where marine sediments from the Paleogene and Neogene epochs are exposed on the surface.
Despite the fact that the vast majority of pitch lakes are remnants of once-active seeps, a handful of them, such as Pitch Lake on the island of Trinidad, is regularly nourished by crude oil that seeps up from the subsurface.

California is the home to the major natural bitumen and asphalt lakes in the world.
The La Brea Tar Pits are the area's first lake.
A series of tar pits are located in the city of Los Angeles, California, United States.
The pits are the most noticeable and distinguishing feature of the 1924-established Hancock Park.
Through the 6th Street Fault, oil from the adjacent Salt Lake Oil Field reaches the surface, resulting in the formation of tar pits.
After the more volatile components of the oil have evaporated, oil seepage produces pools at various locations throughout Hancock Park, which eventually transform into the asphalt.
A fascinating feature of these geological formations is the discovery of fossils of ancient species that were trapped in asphalt at the La Brea Tar Pits.
During numerous centuries, the tar effectively preserved the skeletal remains of these animals.
