Mariner Hill

Mariner Hill (-71.85°N, -68.33333°W) is a prominent snow-free conical hill, rising to about 500 m midway between Syrtis Hill and Two Step Cliffs, situated in the southeastern portion of Alexander Island, Antarctica. It was named by the UK Antarctic Place-Names Committee in 1993 after Mariner 9, the NASA probe which was the first spacecraft to orbit the planet Mars, in 1971.
