Carcross Desert

Carcross Desert is commonly referred to as a desert, but is actually a series of northern sand dunes. The area's climate is too humid to be considered a true desert.The sand was formed during the last glacial period, when large glacial lakes formed and deposited silt. When the lakes dried, the dunes were left behind. Today, sand comes mainly from nearby Bennett Lake, carried by wind. The dunes contain a wide variety of plants, including unusual varieties such as Baikal sedge and Yukon lupine, among others. (Wikipedia).
