Pilot crater is an impact crater in the Northwest Territories, Canada, just north of the Alberta border and near Fort Smith . It is 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 and is deep. Lake trout, northern pike, whitefish, and pickerel are plentiful, supporting a summer market for recreational fishing.
