I just found this part of the Gobi desert by typing in the position marked at the bottom of this shot.
I saw that the black parts are in fact white snow but I didn't catch on that the fanned out formation was valleys with water flowing northwards. My brain told me that water falls down... and thus south! How daft can you get?
I can feel the old age creeping up on me Kim. Ugh!
That's interesting, I've never heard the term Ordnance Survey but then I don't know much about surveying or maps other than my 6' world map that I reference all the time and Google Earth. I bet those maps were made during the war and so we wouldn't have them here in the US.
