I found this book called Treasure Maps of the Superstitions. it is written by a young lady who is a native of Az. Her name is Amy Michelle Mosier. She claims that Foxworthy found the Lost dutchman mine and removed millions in gold. It was in the late 70's or 80's.She also claims that Foxworthy waited for 16 years or better to write his book. kind of make you wonder a bit? I am not a LDM hunter Buck
