What is the largest crater hole in the U.S.?

Hi Sammi.

Believe it or not, the Chesapeake Bay is an Impact site and it's the biggest in the US (90 km in diameter = 60 miles)!!! Of course, it is covered by water. If you are looking for one that is not, there is one in Beaverhead, Montana that is 60 km in diameter (about 37 miles).

For a complete listing of craters, I recommend looking at this web site:

Hope this helps.
