🏜️ Great Sand Hills

The Great Sand Hills, also spelt Great Sandhills, are sand dunes in the south-west region of the Canadian province of Saskatchewan. The Great Sand Hills are the second largest active dunes in Saskatchewan, after Athabasca Sand Dunes, and are part of Great Sandhills Ecological Reserve, which covers an area of about 1,900 km2 (730 sq mi). The sands that make up the dunes are made up of very finely ground sand called rock flour that were deposited near the end of the last ice age. The region around the sand hills is often windy and, as a result, the wind blows the fine sands around creating an ever-changing landscape.
