Rocks & Minerals Of The United States Field Guide

The book is very well made and I've enjoyed looking at it. My only complaint is the descriptions don't truly show all the places you can find them. For example; Unikite is found all over here in Michigan.

Great book, lots of rock information, a great book to have in our museum for visitors to be able to look through.

It is absolutely amazing, very helpful for identification of not only looking for agates but helpful for the ones I hsve.
