Zigzag Bluff is a rock bluff at the foot of Herbert Range
, overlooking Ross Ice Shelf
about 5 miles (8 km) west of the terminus of Axel Heiberg Glacier

in 1911, the bluff was roughly mapped by the Byrd Antarctic Expedition, 1928-30. So named by the Southern Party
of the New Zealand Geological Survey Antarctic Expedition
(NZGSAE), 1961–62, because of the peculiar folding of the marble
on the bluff.
