I found this site while doing some research on some property we own. It has several historical maps of Alabama from various sources. The maps date from 1825 on up. It has some really cool aerial photos of various sites in all the counties. Some show old towns and settlements that no longer exist. Just click on the maps to enlarge. I just thought it was a pretty neat site for researching potential metal detecting locations if anyone is interested.
