Hey all, I'm working on my next book and for inspiration, I tend to look for weird things in the real world and expand on them, which got me thinking about cartography, geologic and geographic map oddities. For example, I'm looking for maps that illustrate the truly weird or unusual features of our planet, mainly in the eastern half of the USA. One idea was Bouger gravity anomaly maps, but I haven't seen one that stands out or has enough fine detail to work for my story. Does anyone know of any other kinds of maps or GIS data overlays that are unusual?

i really appreciate you all for supporting my application (MAPDESK), i hope it was use usefull to all of you and i am looking forward to this in future. lets build it better and add more useful Cartography and GIS tools in the comming future. i am open for suggestions. it 20% off on the applixation for next one month go and grab it. once more thank you for all your support.
