Carcross Desert, located outside Carcross, Yukon, Canada (Coordinates: ), is often considered the smallest desert in the world. Although, this is untrue with the Desert of Maine having an area of 40 acres (160,000 m2). The Carcoss Desert measures approximately 1 square mile (2.6 km2).
Carcross Desert is commonly referred to as a desert, but is actually a series of northern sand dunes; the areas' climate is too humid to be considered a true desert. The sand was formed during the last ice age, when large glacial lakes formed and deposited silt. When the lakes dried, the dunes were left behind. Today, sand comes mainly from nearbyBennett Lake, carried by wind. The dunes contain a wide variety of plants, including unusual varieties such as Baikal sedge and Yukonlupine, among others.
The Yukon Territorial government made efforts to protect Carcross Desert in 1992, but failed due to opposition from locals who use the dunes for recreational purposes.
