That map cracks me up every time I see it. Elko, NV is at 5,000 feet above sea level and is clearly covered in the map. Reno is at 4,800 feet and not covered.
But is it a a US Navy map. Drawn by a third grader. I am not sure what it has to do with the New Madrid Fault. It looks more like globull warming propaganda about where sea level will be after Antarctica melts. Minus the Basin and Range Province.
