The field was discovered in January 1937 by Vaca Oil Exploration Co., which drilled into tar sands about 2,800 feet (850 m) below ground surface. In spite of the extremely viscous petroleum deposits in the producing formation, which they named after their firm – the Pliocene "Vaca" Tar Sand – they were able to produce about 50 barrels per ...
The Athabasca oil sands, also known as the Athabasca tar sands, are large deposits of oil sands rich in bitumen, a heavy and viscous form of petroleum, in northeastern Alberta, Canada. These reserves are one of the largest sources of unconventional oil in the world, making Canada a significant player in the global energy market. [27]
The Tar Sand Triangle is the largest deposit of oil sands in the United States known today. It contains about 6.3 billion barrels of heavy oil, but is thought to have originally held more. At one point the Tar Sand Triangle could have consisted of 16 billion barrels of heavy oil, almost as much as in Utah today. [3]
Tar sands get a lot of bad press, much of it to do with the fact that the extraction and processing of tar sands bitumen creates a lot more pollution than other fuel sources. A few companies are ...
[3] [4] Tar sands facilities were found to be among the top four highest polluters of volatile organic compounds (VOCs)- a major air contaminant. [4] VOCs and other air contaminants are set to increase in the future as a result of continued output from the oil sands. [4] Oil sand pollution is not only set to increase VOCs, but also, acid rain.

This is the only reported instance of human remains found within tar pits. [25] For thousands of years, Native Americans used tar from the La Brea Tar Pits as an adhesive and binding agent. [1] They would use it as waterproof caulking to line their boats and baskets.
Tar sands have affected over 75% of the habitat in the Alberta taiga forest due to the clearing of the forests and the oil ponds that come from the extraction. These tar sands also create awful toxic oil ponds that affect wildlife and surrounding vegetation. Oil extraction also affects the forest soil, which harms tree and plant growth.
