Premise: Archer Peak ( ) is a peak, 110 m high, on the southwest extremity of Possession Island, Antarctica. It was named by the British Antarctic Expedition, 1898–1900, either for A. Archer, Esq., of Australia, mentioned in the preface to Carsten Borchgrevink's "First on the Antarctic Continent", or for Colin Archer who designed Borchgrevink's vessel, the SS "Southern Cross".
Hypothesis: Archer Peak is on the opposite side of Possession Island than the northeast corner.
