The depth and elevation of the great lakes as a cross-section. I was raised on Lake Erie. It is 200 ft at the deepest. It warms and freezes faster than the others and gets whipped up by the slightest weather. 
The great lakes are… great! 
I have been invited to show during a sailing regatta at a Yacht club on Lake Ontario. I will include my work on nautical charts. I have made new work for this event that I would like to share.
