Keith Louis Cromwell was 49 when he was last seen on July 23, 1979, leaving Quarry Island on Lake of the Woods in a motorboat bound for Fog Island. The disappearance is tied to that specific water crossing: he was observed departing one island and never arrived at his intended destination. The national missing-person record lists Quarry Island, Lake of the Woods, near Kenora as the place last known, and the provincial file is OPP reference CR 79-0407.

Cromwell was born in 1929 and is described as a White male about 5 feet 7 inches tall, 146 pounds, medium build, light or fair complexion, blue eyes, short curly red hair, missing teeth and a scar on his nose.

The essential fact is straightforward and unresolved: a planned boat trip from Quarry Island to Fog Island on the afternoon of July 23, 1979, ended with Cromwell never arriving and no verified account of what occurred afterward. Does anyone who spent time on Lake of the Woods around Kenora in 1979 remember that trip or have information that could help fill the gap?
