Wonderful Free Historical Topo Map Resource

[Lensman]

Currently, this collection has over 2,000 historic USGS Topographic maps covering several areas of the United States. The maps are available in various scales and date back as early as the 1800s in many areas. You can seamlessly overlay these maps onto Google Earth. I'm using a 1919 USGS topo map of Sonoma for an area that I've been researching and are going to check out soon. Wonderful resource! Link below:
