An example of a sledge trail running across
a snow field
“After midnight the violence of the wind moderated, and in the morning the sun was shining, though a considerable drift was still running, and a heavy bank of drift lay all around the horizon... Gradually this subsided, and I was able to get some meridan observations with the transit. The drift made the use of artificial horizon impracticable. These observations gave our latitude 85 12 and our longitude but slightly west of the ship at the Sheridan.”- Robert E. Peary in Nearest the Pole, published in 1907
