Melting Glaciers created the Chesapeake BayThe Chesapeake Bay was once the extended valley of the Susquehanna River, which flowed directly into the ocean near the mouth of the bay. The Bay and all its tributaries were once non-tidal freshwater rivers flowing through valleys in the last ice age 15,000 years ago when sea level was more than 300 feet below the present level. As the climate warmed and glaciers melted, sea level rose and the Susquehanna Valley and other tributaries like the Choptank flooded with mixtures of freshwater and seawater.
