Looking for Old Prospecting Maps

[HillshadeHunter]

I'm developing a geospatial analysis tool and I would like to have old prospecting maps for testing.

I don't care if the spots have already been picked clean. In fact, that would be preferable if there is any evidence that the spots were picked clean because if my tool can find those spots then I have some evidence it is working.

Google "mylandmatters". Learn how to use that site as it shows current and a way to bring up historic mining claims in the western U.S.
Good luck
