Peter Browning Dean was 41 when he was last known to be at Tunk Lake in Sullivan, Maine, on November 2, 1987. NamUs lists him as White, brown hair, blue eyes, about 5 feet 10 inches and 180–200 pounds. He had gone alone to his hunting cabin and loaded a canoe with hunting supplies before setting out into a remote part of Hancock County.

The canoe and the supplies were later found floating on Tunk Lake, a deep, irregular, largely undeveloped lake with extensive shoreline and forested terrain. Peter himself was not found. Public information does not describe any confirmed witness sighting after he left the cabin, nor does it list what he was wearing or provide a clear account of how the canoe came to be adrift without him.

The combination of cold water, deep areas, irregular shoreline and remote, heavily wooded surroundings frames why reconstruction and recovery could be difficult. The basic facts remain: an experienced outdoorsman set out alone from a hunting cabin, his canoe and gear were recovered on the lake, and Peter vanished from the known record.

Did anyone in the area at the time remember seeing Peter or his canoe on Tunk Lake that day?
