Geocache Description:

This Earthcache site is at the source of the Susquehanna River, Otsego Lake in Cooperstown, NY. The Susquehanna River it is the longest river on the American east coast and the 16th longest in the United States.

The source of a river or stream is the place from which the water in the river or stream originates. The Susquehanna River is a river located in the northeastern United States. At approximately 444 miles long, it is the longest river on the American east coast and the 16th longest in the United States. The Susquehanna forms from two main branches, with the North Branch, which rises in upstate New York often regarded as an extension of the main branch. The shorter West Branch, which rises in western Pennsylvania, is sometimes regarded as the principal tributary, joining the North Branch near Northumberland in central Pennsylvania. The river drains 27,500 square miles, covering nearly half of the land area of Pennsylvania and portions of New York and Maryland. The drainage basin (watershed) includes portions of the Allegheny Plateau region of the Appalachian Mountains, cutting through water gaps in the lateral mountain ridges in a broad zigzag course to flow across the rural heartland of southeastern Pennsylvania and northeastern Maryland. The river empties into the northern end of the Chesapeake Bay, the ria of the Susquehanna, providing half of the freshwater inflow for the entire Chesapeake Bay.

Geologically, the river is extremely ancient, often regarded as the oldest or second oldest major system in the world. It is far older than the mountain ridges through which it turns, most of which were formed in uplift events of the early Cenozoic era. Like the Hudson, Delaware and Potomac rivers, the basin was well-established in the flat plains that existed during the Mesozoic era. There is evidence that the flow of the ancient Susquehanna was established early enough that it predated the Appalachian orogeny over 300 million years ago, meaning that the river was in existence well before Pangea broke up and formed the Atlantic Ocean.


Before the end of the last ice age, the Susquehanna was a much longer river. The Chesapeake Bay constituted its lower valley before it was flooded by rising waters at the conclusion of the Pleistocene, a formation known as a ria.
