It is 6 kilometres in diameter and the age is estimated to be 445 ± 2 million years (Upper Ordovician).[1] The crater contains Pilot Lake, a pristine fresh-water lake that covers 43 square kilometres (16 mi²) and is 90 metres (300 ft) deep. Lake trout, northern pike, whitefish, and pickerel are plentiful, supporting a summer market for recreational fishing.[2]References1. ^{{cite Earth Impact DB | name = Pilot| accessdate = 2009-08-19}} 2. ^{{cite web | title=Pilot Lake Cabins – Fly-In Fishing | url=http://www.pilotlake.ca/ | accessdate=2007-01-14 | archiveurl=https://web.archive.org/web/20061205051814/http://pilotlake.ca/ | archivedate=2006-12-05 }} External links
