(2) -- The geology is presented more in the context of "episodes"
rather than a total breakdown of rock formations. In other words, we put more
emphasis on types of formation and corresponding time periods than on a hierarchy of
individual formations. In our experience, this makes geologic history easier to
grasp for the average person.
(3) -- Images are always being added to increase the number of views.
Some images will be replaced as better ones become available. Many of these
pictures were taken in primitive fashion during hikes and other outings.
(4) -- Please feel free to contact us if you have a question about the
geology shown. It is impossible to go into much detail on the web pages -- whole
books could be written about some of the places shown!
(5) -- Any comments or corrections are appreciated.

you have purposely disabled it) will show the "definition" boxes as whole web
pages, requiring use of the "back" button to return to the page which referred
(8) -- The map omits city limits and other political boundaries. They
would clutter it up and make it hard to see anything. And in the scope of things
geological, they don't matter a whole hell of a lot.
