Free Topos Maps from USGS

"However there is another way to print free topos. You can download, for free, a high resolution PDF file of any US topo map made. These are the same maps that the Google Earth app is using, but here they are dished out one by one in PDF format. Go to the USGS Map Locator page, and search for the quad you want. You can type in an "street" address just like in Google. Click on the appropriate miniature map and then choose which scale map of the area you want to download. The PDF files of the standard 7.5 minute topo map will be between 6 and 16 megs. You'll need Photoshop or equivalent to crop and size them. Be prepared to use some heavy duty processing power. These are big, very detailed maps."
