What’s a bolide?

To understand Chesapeake Bay, which we transited over several weeks from its mouth to near its headwaters, we must answer the question posed above.  A  bolide is a comet or asteroid-like object according to the Chesapeake Bay Program.  35 million years ago, give or take a few, a bolide struck the lower tip of the Delmarva Peninsula, creating the Exmore Crater.  The crater, as large as Rhode Island and deep as the Grand Canyon,  helped determine how the bay would eventually form when ice age glaciers began to melt approximately 18,000 years ago flooding the ancient Susquenhanna River Valley.  For more of the Bay’s natural history see:
