Are the Illinois and Michigan Canal and North Shore Channel both located in the US?
North Shore Channel The North Shore Channel is a drainage canal built between 1907 and 1910 to flush the sewage-filled North Branch of the Chicago River down the Chicago Sanitary and Ship Canal. The sewage carrying duty has been largely taken over by the Chicago Deep Tunnel, but there are still occasional discharges due to heavy rains.
Ile Aux Galets Ile Aux Galets, also known as "Skillagallee" or "Skillagalee Island", is located in northeast Lake Michigan, between Beaver Island and the mainland, approximately 7 mi northwest of Cross Village in Emmet County, Michigan. The island's Ile Aux Galets Light warns passing ships of a dangerous gravel shoal extending almost 2 mi to the east and .5 mi to the northwest, that poses an imminent hazard to navigation.
