The Duck Galloo Ridge is a mainly underwater ridge, at the eastern end of Lake Ontario, spanning from Prince Edward County, Ontario to Jefferson County, New York.[1] In pre-Columbian times native people used the islands on the ridge as way stations, when crossing the lake. The islands and shoals that dot the ridge have been navigational hazards since sailing ships first started navigating the lake.

This feature is known as the Duck Galloo Ridge. Parts of the ridge rise up abruptly from the lakebed to form rocky underwater shoals; other portions rise up further to form barely submerged reefs; and at a few spots the ridge is exposed above the lake's surface to form low rocky islands.
