  Pilot crater is an impact crater in the Northwest Territories, Canada, just north of the Alberta border and near Fort Smith 54 km (34 mi). It is 6 km (3.7 mi) in diameter and the age is estimated to be 445 ± 2 million years (Upper Ordovician).
  
  The crater contains Pilot Lake, a pristine fresh-water lake that covers 43 $km^2$ (17 sq mi) and is 90 m (300 ft) deep. Lake trout, northern pike, whitefish, and pickerel are plentiful, supporting a summer market for recreational fishing.
