I noticed the Prince Edward Point structure while flying home in my bird GOZooM.
I was approximately approximately 1000′ above Lake Ontario admiring the clarity of the water when I noticed this circular structure. So, I just had to go there and see for myself if the structure had any impact characteristics.
What I discovered in my underwater exploration was dark material deposited from wave motion in the “circular grooves” of the limestone bedrock.
Yours truly preparing an underwater exploration of the Prince Edward Point structure. I was hoping to find a shatter cone or anything relating to an impact.
This image illustrates dark material deposited in a linear manner in a natural groove in the bedrock by wave motion. This explains the “dark” pseudo-crater rim that I saw from the air.
CONCLUSION:  My explorations of the Prince Edward Point structure concluded in a negative result with no impact related geology found. The “circular” geology was probably a result of sedimentary erosion patterns. Oh well……
My documentation of “craters” entails my exploration in the sea, land and air !!
