What if I told you that one of America's most famous waterways is secretly hiding a massive, ancient meteor crater twice the size of Rhode Island?
Or that despite being an inland bay, its jagged shoreline is actually longer than the entire U.S. West Coast?
From violent oyster wars to isolated islands where people speak a 17th-century Elizabethan dialect, Welcome to the Chesapeake Bay.
It's a region often known just for its blue crabs, but one that is actually full of incredible historic and geographic significance.
So here are 15 incredible geography facts you never knew about the Chesapeake Bay.
To understand the physical geography of the Chesapeake Bay, you have to look far beyond the shores of Maryland and Virginia.
The bay's health and hydrology are dictated by a gargantuan watershed that spans 64,000 square miles.
A raindrop falling in the forested mountains of Cooperstown, New York, or rolling off a farm in Pendleton County, West Virginia, will eventually navigate a complex network of streams and rivers to arrive in the bay.
This massive drainage basin includes parts of New York, Pennsylvania, Delaware, Maryland, Virginia, West Virginia, and Washington, D.C., encompassing over 100,000 intricately connected waterways.
Because the ratio of the watershed's land area to the bay's water volume is the largest of any coastal water body in the world, the Chesapeake is incredibly vulnerable to whatever happens on the land.
