"FIND IT FAST MINING LOCATOR" is now available. The packet includes: 1917 claim maps of the Central City and Idaho Springs mining districts showing the claim lines and positions of patented claims, an alphabetical & coordinate index of the claims shown on the maps and a CD with "zoom to area" function.
We have Sanborn Municiple maps that show 19TH century Colorado cities and towns. Until recently these amazingly detailed maps were virtually unknown outside the insurance industry. Available now are period maps of most of the towns and cities of Colorado, Wyoming, and other western states. Most of the maps start in the 1880s with revisions every six years or so.
