The Hudson Canyon

“How is it that a submarine trench rivaling the Grand Canyon is directly related to the Hudson River?”

The Hudson River Valley extends underwater through the Hudson Shelf Valley. At the far end of the Hudson Shelf Valley is The Hudson Canyon. The Hudson Canyon is a biodiversity hotspot reaching Grand Canyon-rivaling depths of up to 3,500 meters/10,500 feet below sea level. Concerned individuals are advocating to designate the Hudson Canyon as a National Marine Sanctuary, which you can learn about here.
