Not sure there actually is a word such as "atop". This photo from the almost top of one of the hilltops (2,1km). Didn't actually manage to climb the rest of 100-200 meters, because it was getting dark, and there were shots to be made before having to hurry back home.
No sunset as I originally wanted, but these pre-stormy clouds were good enough for me. Canon 5D mark II, 16-35 lens, polarizer and nd filters.
