Re: Are James Bay and the Gulf of St. Lawrence impact sites?

Denni:

The short answer to you question is: I don't know. I have done some 
checking and have come up short on these two structures. However, I have 
some suggestions.

As I am sure you are aware, it is possible for a structure to look 
uncannily astroblemic and yet not be an impact structure. It is necessary 
to have some hard, geologic evidence. I suggest that you contact the 
geology or earth-science departments at the universities in the eastern 
part of Canada, and also the Canadian Geological Survey. These are the 
organizations most likely to be able to answer your questions. There are 
also some amateur organizations that are interested in impact structures. 
These groups, which are easily found if you do a web search for meteorite 
or impact, may have some information about these two localities. 

I am sorry that in the time available I couldn't find definitive answers 
for you.

Good luck,
