Way cool! A lot of things going on there. I didn't realize the California valley and the whole state of Louisiana were so low or that the Appalachians were as limited as they are. Nevada looks just covered with isolated N-S mountain ridges. Thanks Seth. Anything like that for Europe?
Nope, but that world map is just great : http://www.shadedrelief.com/natural3/pages/extra.html
Thanks Franck.
This is rather beautiful, the only thing puzzeling me, is on all those documentaries of Yellowstone, they show it very prominently noticeable from a heightmap. Here it's almost all together invisible.
