Here the sun is at its most northerly point. If one were to stand on the Northern Tropic, the sun would appear directly overhead at noon(ish). You would have no shadow. It would also rip across the sky. If you were above the Arctic circle, the sun wouldn’t set for a good chunk of time (depending on how far north one is). Higher than the Antarctic circle, and darkness rules the land, the penguins, and documentary filmmakers. The auroras are quite spectacular.
