Gem Trails of Arizona

Summary: Gem Trails of Arizona
Review: I own three different revisions of this book. All are very useful for amateur rock hounds. My sons and I have visited about a dozen of the listed sites and all have produced nice specimens.

Summary: Needs better maps and/or GPS coordinates
Review: This review is based on visiting only 4 of the sites covered in the book. For three of the four sites, I found the hand drawn maps in the book rather confusing. Based on my limited experience, it appears that most AZ roads outside of medium to large population centers are rough, may be unmarked and, if marked, often have names/numbers that may not match the book, the gazetteer, or USGS topo maps. Furthermore, some of these collecting sites are old mine workings that are not readily visible due to overgrowth. In any case, GPS coordinates would take some of the confusion out of the location descriptions. Better maps would help also. However, we did eventually find what was advertised and this certainly is a helpful guide and worth the money spent.
