A 200-year-old cannon resting on the bottom of the Detroit River will stay there a little longer, after weather, high waves and poor visibility foiled an attempt to raise it Wednesday.
Detroit police divers spent a frustrating day searching a 25-foot-by-25-foot patch of river bottom without success, said Joel Stone, curator at the Detroit Historical Museum. Underwater visibility was so poor they were forced to search by touch.
The cannon was found in late July, and the site was marked by GPS, about 20 feet underwater and about 200 feet from the seawall behind Cobo Center.
Finding a cannon of such age in this part of the country is rare.
"On the East Coast, cannons were fairly common," Stone said. "But here on the frontier, we got what we could get."
