This landscape looks like an abstract painting but is in fact a shallow river which feeds into one of the largest and deepest lakes in Canada.
The William River flows into Lake Athabasca, whose sand dunes are estimated to be around 8,000 years old and formed near the end of the last ice age.
Athabasca Sand Dunes, in Northern Saskatchewan, Canada, is extremely remote - with no communities, services, facilities or roads.
The area boasts a boreal forest as well as a desert, and the landscape is sculpted by the wind and water with the river and stones all shaped as a result of the elements.
