Tar pits, sometimes referred to as asphalt pits, are large asphalt deposits. They form in the presence of petroleum, which is created when decayed organic matter is subjected to pressure underground. If this crude oil seeps upward via fractures, conduits, or porous sedimentary rock layers, it may pool up at the surface. [1]

Ultimately, tar pits symbolize the contrast between the harsh conditions of migrant labor and the refusal of society to acknowledge that labor. The Under the Feet of Jesus quotes below all refer to the symbol of Tar Pits.

Tar Pits (Symbol) The tar pits symbolize migrants' marginal position in American society, where they are largely unseen and unheard. Drowning in a tar pit echoes the erasure of migrant labor: a creature's life is sacrificed, but never acknowledged. Animals are simply swallowed by blackness.

The La Brea Tar Pits are world famous and are the only registered National Natural Landmark in Los Angeles County (and one of 39 sites in California). Almost every Angeleno knows about the La Brea Tar Pits, as do many non-Angelenos. The story of this unusual natural feature has stirred scientific interest and imagination for more than a century.

2024年8月30日 · Using land donated to the County of Los Angeles by George Allan Hancock in 1924, Hancock Park has produced over one million mammal fossils and one human skeleton from the tar pits near downtown Los Angeles. The oil for the tar comes from the Salt Lake oil field, about 1,000 feet bel

A sculpted mammoth shows visitors to the La Brea Tar Pits what these ancient animals might have looked like, but the pits themselves have looked the same for thousands of years. How did they form, and what discoveries lie beneath the sticky surface?

2021年8月6日 · Alejo compares animal bones in tar pits to human bones. He said to Estrella, “Once when I picked peaches, I heard screams. It reminded me of the animals stuck in the tar pits”. Estrella, after realizing her family’s distressing situation, later compares her family to a “tar pit made of bones”.

Tar pits form when crude oil seeps to the surface through fissures in the Earth's crust; the light fraction of the oil evaporates, leaving behind the heavy tar, or asphalt, in sticky pools. Tar from the La Brea tar pits was used for thousands of years by local native Americans, as a glue and as waterproof caulking for baskets and canoes.

The most successful entrepreneurs were John Hambleton and Judge Lovejoy who in 1864 dug shallow pits, 8 to 10 feet deep, near active seeps in what became known as the Asphalto area. They built a small still and refined the tar they collected into lamp kerosene which was shipped by wagon to their agents in Stockton.

Below this strata, the tar pit vent continues down through another layer of gravel, sand, and fine-grained marine sediments to oil reservoirs about 2,000 to 6,000 feet below the surface of the earth. This oil-bearing second layer is called Upper Miocene, and it forms the basin of the Los Angeles region (Quinn, 1992; Stock and Harris, 1992, p. 10).
