Thumb Promontory was unofficially named by a 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.
