The pass lies between unnamed peaks and permits passage from the area at the head of Carryer Glacier to areas in the southern part of Bowers Mountains. So named by NZGSAE, 1967-68, because ascent of the pass required an all night trip with much zigzagging and climbing; thus named after the genus of land snail, Helix.
