There might be more sunken cannons in the depths of the St. Lawrence River near Carleton Island's Fort Haldim, according to a group of archaeologists and scuba divers.
The initial survey of a small area off the island this summer conducted by the group showed no evidence of large iron objects. However, the group hopes to expand the search once it gathers more historical evidence that there are, in fact, more cannons disposed of by the British in the early 1800s.
Dennis R. McCarthy, co-founder of the St. Lawrence Historical Foundation, a nonprofit organization based in Cape Vincent that conducted the survey, said the search began after two scuba divers claimed in 2008 that they saw a sunken cannon off of Carleton Island several years ago.
"Our aim was to go out there, do a survey, locate the cannon and measure it," said Mr. McCarthy, a certified scuba diver and resident of Cape Vincent.
