Consider making an Oceanography or Geology course part of your educational experience at Mira Costa
College. Here in coastal San Diego
County we are surrounded by a fascinating and readily accessible geologic and
oceanographic environment. Studying
oceanography and geology here is interesting, fun, and relevant
to all of our lives. Feel free to
contact me if you have questions about oceanography or geology classes,
including my ONLINE
sections of Oceanography and Environmental Geology
(see below).
I have taught college earth science for most of my
professional life, first at the University of Arizona in Tucson, then at
Oberlin College in Ohio, and now Mira Costa College, where I have been since
1997.
Hard Road West (my recently published
book)
In addition
to teaching, I do research on the geology of the American West and how it
influenced the route of the historic overland trails and the experiences of
mid-nineteenth century overland emigrants.
I recently completed a book about my explorations along the historic California
Trail—the overland route the forty-niners took during the California gold
rush.

CORDILLERA (my new book project)
I’m
currently working on CORDILLERA:
A Geologic Journey from California to the Rocky Mountains. This book takes
the reader on an armchair “field trip” across the American West and explains
the science behind the scenery.

The
fault scarp above formed when the Sierra Nevada lurched upward six feet during
a major earthquake in the Owens Valley in 1872.
Earthquakes represent the growing pains of mountains. Every quake adds a little bit to the uplift
to a mountain, and the rugged, spectacular topography of the American West is
the product of millions of quakes over millions of years. From CORDILLERA: A Geologic Journey from California to the Rocky
Mountains.
