Middle of a project, wondering if there is a better historic topo source than TheNationalMap for finding historical maps for an area. Coring some lakes, would be nice to know that they've been there for at least a few hundred years.
The OldMapsoline is the best source I know for an old map. This map are mostly from the eighteenth century. In the home page you can insert a location into the search box One other option is move around the map and see what pop out In the left bar you have a list of maps and their descriptions. When you click on a map you it will open a new window that allowed you to download the map.
