The Panther Mountain Crater:

The link with the article has 14 pictures of other craters. One, #3 is Popigai Crater in Siberia which is the same age as the Chesapeake Meteor. It is more than 60 miles in diameter. There was also a similar date, 9 mile diameter crater off Toms River, NJ. At the link, picture #2 also shows a crater which could be from the same period. There is a book by Poag (sp?) about the Chesapeake Meteor. [Can’t find the book right now to be more accurate. Darn, even with the internet I still have too many books and too much paper.] Here is the link which as I said may be the original or might link directly to Popigai: http://www.space.com/php/multimedia/imagegallery/igviewer.php?imgid=273&gid=21
For those who might want to search maps, and/or like technical detail, check out this link on how river flow is affected by craters:http://www.space.com/php/multimedia/imagegallery/igviewer.php?imgid=273&gid=21
Well, that didn’t work. I go the same link as previously. For some reason the hydrology link did not copy. Is it because there was (PDF) before the title? At any rate I found it by Googling “Mistasin Lake, Canada”, the article was about 10 down, and including about four different crater drainages.
