Might I make one more suggestion when visiting the parks of Southern Utah? Get a copy of this book, "
Geology Unfolded, an Illustrated Guide to the Geology of Utah's National Parks." by Thomas Morris, Scott Ritter, and Dallin Laycock.
The authors are two BYU geology professors and a grad student. It's one thing to stand in awe at the beautiful rock structures of this area. It is quite another to have a basic understanding of how they came to be. The book is written for tourists, not geologists and best of all is only 10 bucks.
It is very hard to find since you can only get it from the publisher. You can look through the book on the link above. The phone number for ordering is on the "Price List" link at the top of the page.
No, I have no financial interest in the book. Just found it valuable when we went through the various parks.
