|Chessie coloring book|
An early report of Chessie may date from 1840. The creature described is likely to have been a turtle. In 1936 an unknown reptile was seen in the Bush River, which flows into the Bay, by a helicopter. A serpentine creature was reported by fishermen in 1943. In 1978 a serpent was reported in the Potomac River, which also flows into the Bay. There were other sightings in this river in 1980. In August, 1984, there were further sightings. A possible sighting from a boat named the Impasse was reported in 1980, but those involved never claimed to have seen a monster, merely anh animal, which may have been a manatee. In 2014 a serpentine creature, 25'-30' long, was seen from the Arundel Beach Road at a distance of only 5 feet.
My own suspicion is that we may be dealing here with large eels. However, we should not forget that a dinosaur called the Astrodon roamed Maryland, but the fossil record would indicate it died out 100 million years ago. Could there be a few lingering specimens off the Maryland coast?
