Carswell is an impact crater within the Athabasca Basin of the Canadian Shield in northern Saskatchewan, Canada.^[1] It is 39 kilometres (24 mi) in diameter and the age is estimated to be 115 ± 10 million years (Lower Cretaceous). The crater is exposed at the surface.

Access[]

The Carswell Crater can be reached by Saskatchewan Highway 955. The 245 kilometres (152 mi) gravel road begins in the village of La Loche and ends at the old Cluff Lake mine site within the crater. The Cluff Lake uranium mine produced over 62 million pounds of yellowcake during its 22-year operating life.^[2] Since the mine is now closed and decommissioned, there are no travel services in the vicinity and no functional airstrip. Motorists driving to the crater need to carry sufficient fuel and supplies for the round trip back to La Loche.
