The Hull Glacier flows in a northwest direction to Hull Bay on the coast of Marie Byrd Land. It passes Smoot Rock, Frost Cliff and Mount Steinfeld, which lie to the north. West of Mount Steinfeld it is joined from the right by Kirkpatrick Glacier, which flows down from Strawn Pass to the south of McDonald Heights. The combined glacier flows past the Erickson Bluffs, which lie to the northeast, and is joined from the left by Rubey Glacier. It passes Miller Spur on the southeast and enters Hull Bay just east of Lynch Point.
