I found mine at a prospector shop but it was recommended to me here on the treasurenet.I did have a hard time finding it in any book stores. The name of the book is "Larune's rockpecker Notes'" it is written by T.D. Larune.The book is published by skill//quest co.675 Fairview dr. #246 Carson city nevada 89701.It shows secrets clues tips, hints and lots of data.I had to pay @ $35 for this book but I feel it is well worth the money if you are going to be a prospector. Hope this helps you find the big-one!!!! Taylor from Montana!!!
