The Overview: Alberta Tar Sands
Athabasca Oil Sands
These satellite images, taken from July 1984 through May 2011, reveal the development of the Athabasca oil sands, commonly called "tar sands," which lie at the heart of Alberta’s oil deposits. Tar sands mining
, which has become a significant issue for environmentalists, has been rapid and extensive, growing to cover nearly 260 square miles of the Canadian province by 2011. It has also proven lucrative for Alberta: Nearly 2 million barrels of oil are produced every day, according to the provincial government
, generating billions of dollars in revenue annually. Production is expected to grow to nearly 4 million barrels per day over the next decade. (Image credit: NASA Earth Observatory)
