Map of Alberta showing extension of oil sand occurences (left) and labelled satellite image (right) with oil sand open-cast mines and in-situ production sites along the Athabasca River north of Fort McMurray. The satellite image shows the situation in 2011. The photographed area ist the only place in Alberta in which oil sands are mined in open pits.
