Trail Information

On June 20, 1932 this steel drill barge was sunk due to an explosion. The steel drill barge America was used to dynamite shoals along the St. Lawrence River.  The shoal side gives evidence to the American's work with the blasted rock rubble along side. The usual path back is swimming upstream on the shoal side and accessing the guide rope back to the buoy area to access your boat. This site rests at a depth of 75', upside down across the shipping channel from Singer Castle and Dark Island east of Mallorytown Landing. Normally a guide line is buoyed immediately east of Black Buoy #167 on the downstream side of the shipping lane.  Use caution when diving.




Approximately 600 ft off the southwest corner of Singer Castle’s Dark Island between Brockville and Malloytown.

Depth 78 ft (23.8 m)
