# Thumb Promontory

Thumb Promontory (84°48′S 116°18′W﻿ / ﻿84.800°S 116.300°W﻿ / -84.800; -116.300) is a prominent rock spur on the north side of Lackey Ridge, Ohio Range. Thumb Promontory was unofficially named by a New Zealand Antarctic Research Program (NZARP) field party to the Ohio Range, 1979–80. The name was formally proposed by geologist Margaret Bradshaw, member of a second NZARP field party, 1983–84. So named because of the similarity of the upper part of this feature to an upturned thumb from certain angles.
