MY AMATEUR ADVENTURES IN CRATER EXPLORATION

by: Charles O’Dale

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 combined my hobbies of astronomy, geology and flying to explore impact craters and 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, in some instances, these forces have “cross sectioned” the craters to ease our study. I find the geology in these craters and structures fascinating!

This is me “on the job” exploring impact craters, this time at the Barringer Impact Crater.

While studying the physics of impact crater sites, I have found that circular geological features can also be produced by a number of geological processes.

Halliday I., and Griffin, A.A. 1964:  Application of the scientific method to problems of crater recognition  Meteoritics, vol. 2, No. 2.

These geological processes may include igneous activity (diatremes,  maars, calderas, volcanoes, or syenite/plutons), dissolution and collapse of salt or carbonate rocks by groundwater (dolines), salt or shale diapirism, regional tectonism (circular fold-interference patterns or stratified circular features), glaciation (kettle holes), carbonate mounds, and by meteorite impacts (Stewart 2003).

Stewart S. A. 2003: How will we recognize buried impact craters in terrestrial sedimentary basins? Geology 31:929–932.

This is me fulfilling a lifelong dream – standing on the rim of the Pingualuit crater!

“Civilization exists by geological consent …. subject to change without notice.”

– W. Durant –

I flew my airplane (a C177B – GOZooM) to Puerto Rico to explore a crater only to find that someone had built a radio telescope in it!

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 and structures. 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.(A few of my expeditions actually resulted from suggestions made from readers of this site).

Many of the other exploration trips that I have made in GOZooM and on foot can be viewed here.

Unless otherwise indicated, all of the aerial images my web site were taken from my chariot “GO ZooM”. FYI, a report on one of our crater exploration trips can be viewed here: Part 1 & Part 2.

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