The First People
People came to the Bay more than 10,000 years ago. For thousands of years they used its rivers to travel and trade.[1]
John Smith’s Map
In 1608 John Smith made two long trips around the Bay. His map was the first detailed map of the Chesapeake. It shows more than 200 Native towns.[2]
Oysters, Boom and Bust
Oysters began to fall in the late 1800s. The causes were overfishing, disease, lost habitat and pollution. By the 1990s only 1 to 2 percent of the old oyster numbers were left.[3]
