To the southwest, the fjord opens into the Murchison Sound of the Baffin Bay.

[1] In 1891 a spot in the southern shore near the mouth of the fjord was chosen as a place for the recovery of Robert Peary during his Second Greenland Expedition.

A house was built and the site was named "Red Cliff".

It runs in a roughly NE/SW direction east of Cape Robertson, with its mouth north of Cape Cleveland, beyond the western end of the Inglefield Gulf.

[4] The Sun Glacier discharges from the Greenland Ice Sheet at the head of the MacCormick Fjord and its terminus is a 30 m (98 ft) high wall; the smaller Scarlet Heart Glacier has its terminus on the eastern shore of the inner fjord, about 20 km (12 mi) from its mouth.
