Old aerial photographs

[Onshore]

For those who may have an interest, you can download old USGS aerial photos here: http://earthexplorer.usgs.gov/ You do need an account to download photos but there is no charge to have one so that should not be a problem. You can enter a search location using an address, coordinates or by zooming in and marking a location on the map provided. Once you select a location, move to the "Data sets" tab. Expand the "Aerial Photography" option and select "Aerial Photo Single Frames" this will access photos going back to the 1930's and 40's.
