The scientific study of impact structures began only about 50 years ago. I’m dating myself, but that was about the time my interest in impact craters started. Like any kid, I spent hours looking at the craters on the Moon through my old telescope. Would I ever get a chance to explore a crater? Well since retirement, I have combined my hobbies of astronomy, geology and flying to explore the impact structures in North America from the air and ground. You may think that the natural geological forces on our planet would have destroyed any features of impact craters. But I’ve found that, in some instances, these forces have “cross sectioned” the craters to ease our study. Many of the exploration trips that I have made in my airplane and on foot can be viewed here.

The craters that I have explored will be posted in this web site grouped by crater type and size. My science background plus the experience that I have gleaned from my past profession of semiconductor failure analysis has given me the incentive to document my analysis of these craters. I encourage anyone to please contact me if they note any errors that I may have made in my documentation or if they have something to add.

If you ever find yourself in Ottawa, please come to one of the monthly meetings of the Ottawa Centre, Royal Astronomical Society of Canada.
