USGS google Maps Google Earth Topo Quad Index KML

Thanks to Scott and the crew at DDS in Lakewood, CO for making available this sweet USGS quad index, easily used within Google Earth or google Maps. Simply browse around, locate your quad, click on the bubble icon, then download the free TIF or purchase a high-res digital version or paper map from DDS... freaking awesome! Here's the KML file
Note, the file is large and takes some time to draw fully in G. Maps!
