Unique map series shows changes in gold & gem fields over the last 100 years in selected western states. Each map package includes current USGS maps of the state along with antique turn-of-the-century maps of the same areas for comparison.
This is a good resource for my gold panning adventures. There are several streams I had planned on trying but now won’t, as they aren’t gold-bearing-this will save me a lot of gas and a lot of frustration. Also explains why I had so many skunked days last year, panned several nice looking streams that turned out not to have gold.
