Pilot crater
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.
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.
