The Athabasca River runs down the left side of this orthorectified image of eastern Alberta, Canada. The black and white areas by the eastern and western banks of the river are the Athabasca Oil Sands.

Oil sands, also known as tar sands, are large deposits of extremely heavy, semi-solid crude oil mixed with silica sand, clay minerals and water (this mix is known as bitumen).

Damage to the boreal forest near the sands is occurring as the area is deforested in order to extract oil from the tar sands. Click here for a previous article including photographs of this destruction.

The Athabasca River originates from the Columbia Glacier, at an altitude of approximately 1,600 meters (5,249 ft), in Jasper National Park in Alberta, Canada. The river flows 1,231 km (765 mi) along icefields and through gorges, before draining into the Peace-Athabasca Delta near Lake Athabasca.

This orthorectified image focuses on a stretch of the river along which the Athabasca Oil Sands are located, near Fort McMurray. The oil sands are crude bitumen (a type of crude oil) mixed with silica sand, clay minerals and water. Other oil sand sites can be seen further away from the riverbanks, to the right of the center of the image.
