Bibliography.....................................................................................................510 iv A Location Guide for Rock Hounds in the United States Preface Each year I vacation in the field, collecting gem and mineral samples somewhere in the United States or Canada, and each year I spend hours looking through reference materials to plot out my trip (to include locations which interest me). Last year as I started this annual process, I decided to find a new and more complete reference to reduce my research time. To my dismay, there were some new references for individual states, but the most useful references were no longer in print and were rarely available to collectors at local libraries outside of USGS repositories. This prompted me to collect all my books and personal references, along with many trips to the reference library, and try to put together a useful tool for some of my friends. It should be said that my personal contribution, outside of editing, was only about 1% of this effort. Be sure to examine the Biography for excellent sources for further information. The format used was from Gems and Minerals of America, my favorite reference (even considering its age — this could almost be considered an updated version). This is by no means a complete end all reference and some of the references are more of historical value for new exploration than anything else, but there is enough information to be useful to most gem and mineral collectors. Generally, Minerals are capitalized while rocks have been left lower case. This is the 5th printing and each time updates have been added (and each time I tell myself that I will not do this again). It goes without saying that property owners should be asked for access and collecting rights, so remember you were told. If in doubt, a county map will tell you who the legal owner is. Good Hunting. I would like to thank many people for the career opportunities and encouragement needed to complete this listing. Mitch Albert, Andy Bettman, Eric Kurtz, Vince Kurtz, Erwin Mantei, Art Rueff and others for their help through the years. Special thanks
