What are La Brea tar pits?

La Brea Tar Pits are a group of tar pits around which Hancock Park was formed in urban Los Angeles. Natural asphalt (also called asphaltum, bitumen, pitch, or tar— brea in Spanish) has seeped up from the ground in this area for tens of thousands of years. The tar is often covered with dust, leaves, or water.

Where are the tar pits in Los Angeles?

The George C. Page Museum of La Brea Discoveries, part of the Natural History Museum of Los Angeles County, was built next to the tar pits in Hancock Park on Wilshire Boulevard.

When was the La Brea tar pit museum built?

Where did the Tar in the Great Lakes come from?

The tar pits visible today are actually from human excavation. The lake pit was originally an asphalt mine. The other pits visible today were produced between 1913 and 1915, when over 100 pits were excavated in search of large mammal bones.

Does LA have a volcano?

Of those, several areas have had eruptions in the last 3,500 years. Geologically speaking, that's pretty recent, but it's a while on human timescales. More importantly, none of them are all that close to Los Angeles. The nearest volcanic area is the Coso Volcanic Field, about 181 miles away.

Why do the La Brea Tar Pits bubble?

In 2007, researchers from UC Riverside discovered that the bubbles were caused by hardy forms of bacteria embedded in the natural asphalt. After consuming petroleum, the bacteria release methane. Around 200 to 300 species of bacteria were newly discovered here.

What is the La Brea Tar Pits made of?

asphaltThe tar pits are thick, sticky pools of viscous asphalt (the lowest grade of crude oil) that has oozed to the surface from a large petroleum reservoir. They have yielded the fossilized skulls and bones of trapped prehistoric animals as well as one partial human skeleton and many human artifacts.

Are there human remains in the La Brea Tar Pits?

The remains, first discovered in the pits in 1914, are the partial skeleton of a woman. At around 18–25 years of age at death, she has been dated at 10,220–10,250 years BP (Before Present). These are the only human remains to have ever been discovered at the La Brea Tar Pits.

How deep are the La Brea Tar Pits?

3. The tar pits are only a few inches deep! Did you always imagine prehistoric animals sinking into the tar pit goo like it was a sticky quicksand, until they finally sank out of sight?

What happens to the fossils after they are removed from the tar pit?

Every fossil dug up from the Tar Pits has a characteristic brown hue as a lasting stain from the asphalt. Sometimes specimens can become damaged or cracked during the fossilization process. In the Fossil Lab the team can repair or reconstruct the bone using a transparent, glue-like adhesive (Paraloid B-72).

Why is it called La Brea?

In Spanish, "la brea" literally means "the pitch." And no, not the kind of pitch a used car salesman tries to make, nor the act of hurdling a baseball at 95 miles an hour towards a dude with a wooden stick. It means a pit or divide in the land, and "brea" is actually a Spanish word for tar.

What caused the eruption of La Palma?

Well, the true cause of the volcanic eruption of La Palma is due to an underlying hotspot, just like the Hawaiian hotspot. This hotspot has moved gradually over the past few millions of years to the west creating new chains of islands. The largest ever eruption from this hotspot was a VEI-7. I’ll post a couple videos detailing these islands, and this also includes the La Palma island/volcano as well known as Cumberland Vieja.

What happened before the Soufriere Hills eruption?

This process can happen naturally however. Before the 1996 eruption of Soufriere Hills, the top of the volcano was plugged by a large lava dome. As the pressure built beneath it, the dome began to bulge and eventually, when the pressure became too much, the lava dome collapsed and a large explosive eruption was generated.

What is a stratovolcano?

A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers (strata) of hardened lava, tephra, pumice and ash. [1] Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile with a summit crater and periodic intervals of explosive eruptions and effusive erupt

What are the most active volcanoes in the Canaries?

The younger Cumbre Vieja, the southern volcano, is one of the most active in the Canaries. The elongated volcano dates back to about 125,000 years ago and is oriented N-S. Eruptions during the past 7,000 years have formed abundant cinder cones and craters along the axis of Cumbre Vieja, producing fissure-fed lava flows that descend steeply to the sea. Eruptions recorded since the 15th century have produced mild explosive activity and lava flows that damaged populated areas. The southern tip of the island is mantled by a broad lava field emplaced during the 1677-1678 eruption. Lava flows also reached the sea in 1585, 1646, 1712, 1949, and 1971.

Earth presently has a solid crust ranging from 40 to 60 miles thick. It is comparatively thinner than the shell of a hen’s egg. Earth’s crust is under continual pressure from slow but extremely powerful currents in the magma below, pressure sufficient to move continents around. Sometimes this separates continents, in other places, continents are rammed together.

What was the Rancho La Brea Project?

During the mid twentieth century excavation and data gathering techniques improved, as did our ability to extract knowledge from data and specimens neither noted nor collected by the early excavators. Early collectors concentrated their efforts on the remains of the larger, more spectacular plants and animals and rarely noticed or collected those of smaller organisms and important information pertaining to geology and specimen orientation was not often recorded. To help rectify such collecting biases, the Rancho La Brea Project began on June 13, 1969 by resuming excavation of a major deposit of fossils in Pit 91 that had been discovered 1915. Newly developed techniques, in concurrence with established paleontological and archaeological methods, were employed to intensely sample and carefully record biological and geological data in the resumed excavation.

What did the Scouts see while crossing the basin?from en.wikipedia.org

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 was some distance out of the way we were to take, the Governor [Portolá] did not want us to go past them. We christened them Los Volcanes de Brea [the Tar Volcanoes].
