Once, when thick sheets of ice covered North America, the sea
was much lower than it is today. Then, the area we call Georges
Bank was part of the mainland. It stretched into the Gulf of Maine
from the end of what is now Cape Cod. Geologists call that early
form of the Bank Georges Cape.
Twenty-six thousand years
ago, the ice that covered Georges Cape began to melt. After about
1,000 years, the surface was fully exposed. But the air was so cold
that the only life that could survive there was tundra. Georges
Cape measured 53,000 square km, a little more than one-third bigger
than the area Georges Bank encompasses today.
