The mapped trace of the ancient Delaware River cutting across the shelf and connecting with Wilmington and Baltimore Canyons. This river channel was active during the Last Glacial Maximum, approximately 20,000 years before present. Rivers contributed to the formation and expansion of particularly large shelf-indenting submarine canyons.
