Francis R. Foster was a 33-year-old man who disappeared during a canoe trip through the remote Quetico–Basswood Lake wilderness in northwestern Ontario. Foster and his 21-year-old companion Robert Warren were reported missing on May 25, 1974, after last being seen earlier in the trip with a third, unnamed companion. Authorities later recorded a prevailing theory that the canoe may have capsized and the men drowned, but no location, weather details, or physical evidence was recovered to confirm that sequence. Foster is described as a white male, thin build, about six feet one inch, possibly with a mustache when last seen.

Does anyone who paddled those routes in 1974 remember meeting Foster, Warren, or their unnamed companion?
