    Manicoagan is a recognized meteorite impact structure.      

Example 1- Manicougan-unmarked

     Notice the dense chain of circular features with a southeast trend just to the west of Manicouagan Lake. 
This might indicate a terrestrial origin of this group of circular features (a hotspot trail?).
