Sand dunes rise from the valley floor, shaped by wind into curves and ridges, bare of vegetation except where hardy plants cling to the edges. This is the Carcross Desert, sometimes called the world's smallest desert - though 'desert' is a stretch for a place that gets twelve inches of rain annually. The sand is a glacial leftover, lakebed sediment exposed when ice-age Lake Bennett drained. Now the wind sculpts it, the locals sandboard it, and visitors arrive to photograph a scene that makes no sense in the subarctic. A desert in the Yukon. Geography has a sense of humor.

Technically, no - it receives too much precipitation to qualify as an arid climate, and it's more accurately described as a series of sand dunes in a semi-arid microclimate. The 'smallest desert' claim is marketing more than science. But the dunes exi...
