November 6, 2019. The Susquehanna River flows more than 700 kilometers from upstate New York to Maryland, draining into the Chesapeake Bay.
The river's watershed covers more than 70,000 square kilometers and is the source of more than half of the fresh water in the Bay.
December 24, 2019. This photograph from an astronaut aboard the International Space Station shows a portion of the Susquehanna near Harrisburg, Pennsylvania.
Here the river cuts through folded rocks of the Valley-and-Ridge province of the Appalachian Mountains.
The ridges are composed of sandstone and conglomerate, which are relatively resistant to erosion.
The valleys are underlain by limestone and shale, which are softer and more susceptible to erosion.
Farms that now occupy the valleys are a mainstay of Pennsylvania's economy.
However, they are also a source of nutrient and sediment pollution carried by the Susquehanna into the Chesapeake Bay.
