It is a plug or dome of trachyte through which a deep, perfectly conical crater has been drilled by a basaltic explosion. The white trachyte of the hill is obscured by a thin covering of black moraine. Named by the NZGSAE, 1958-59, for the late Colin Todd, an outstanding young New Zealand and Himalayan climber and medical research worker, who had a strong influence on the development of techniques used by mountaineer members of NZ Antarctic Expeditions in the period 1956-59.
