Great album!

Google Earth is mind blowing. So are all the USGS 7.5 minute maps that led to such geographical precision.
Do you know how from plane or chopper flights the USGS were able to determine the number of 40' intervals over such a vastly complicated country? Aerial sonar?
Maybe a distance to elevation equation.

Need to check to see if any FBI agents are parked outside without leaving the comfort of the screen.
