Geology Guy

Now teaching earth sciences in San Diego area colleges

Currently, I am teaching environmental and physical geology, and oceanography at MiraCosta and Miramar Colleges, as an adjunct professor. I will be retiring at the end of the current semester, 1 June 2016.

I have over fifty years experience in geology to draw from in my classwork. My collection of 35-mm slides and digital images includes a great deal of material relevant to my teaching, and I am able to include these images in my course material. I own seven digital cameras, up to a Nikon D200 single-lens reflex. I own three scanners, including a Microtek ScanMaker 9800XL 12"X17" flatbed with transparent media adapter, and a Nikon Coolscan 8000ED slide and negative scanner. With these tools, I am able to convert my older graphics to digital forms for use on the web and in the classroom.

My experience as a graphic artist and web designer contributes to my abilities to explain the sometimes-difficult concepts involved in the earth sciences. I created web sites for my teaching, which can be seen at I now have seven web domains, plus numerous sub-domains. I believe it is my responsibility to share my experiences with the world, just as others have enlightened me in the past.

I consider myself to be an "old-school" geologist, in that I take a very broad view of the science of geology. To me, the study of Earth includes not only solid earth, but the hydrosphere, atmosphere, and biosphere as well. In other words, I subscribe to the Earth Systems Science (ESS) approach. I remain a generalist in a world full of specialists. For example, the book set Geology of Wisconsin was the first geological survey of the state of Wisconsin, completed in 1879 by T. C. Chamberlin. This work included studies of plants and animals, even "Economic Relations of Wisconsin Birds." Chamberlin is one of my heroes.

John Muir was also one of my Wisconsin-based heroes. As he said in My First Summer in the Sierra, "When we try to pick out anything by itself, we find it hitched to everything else in the Universe."

I completed my master's thesis in geology at San Diego State University, a copy of which is online at

I am a past president of the San Diego Association of Geologists, and remain active with the organization.
