During my aerial meteorite crater explorations over various points of the North American Continent, I have noticed and documented a few geological features that are suspiciously shaped like meteorite craters. Also, I have investigated a few that were suggested by people who have contacted me after reading my crater articles. I have listed below the “crater like” structures that I have documented and could be confirmed as impact related if in the future evidence is found. I will be periodically adding more features as I visit them. If you have any additional information on any of the structures that I have documented or any new possible meteorite craters, please let me know.
