It's Nice that those are in color, but the freakin GlobeXplorer pisses me off..
*I was gonna say try
www.terraserver.com but it's GlobeXplorer too... wtf
it used to be a nice free USGS site. LAME*
Edit 2: Turns out TerraServer doesn't have the GlobeXplorer plastered
everywhere, but you can't zoom in very far.
