68th degree

Edgar Allan Poe, "A Descent into the Maelström", 1841

We are now close upon the Norwegian coast — in the sixty-eighth degree of latitude — in the great province of Nordland — and in the dreary district of Lofoden. The mountain upon whose top we sit is Helseggen, the Cloudy. Now raise yourself up a little higher — hold on to the grass if you feel giddy — so — and look out, beyond the belt of vapor beneath us, into the sea.
