Esser Bluff (77°38′S 166°54′E / 77.633°S 166.900°E / -77.633; 166.900) is a rock bluff rising to about 600 metres (2,000 ft) on the southeast margin of Turks Head Ridge, Ross Island. The bluff is 1.1 nautical miles (2 km) east-northeast of Grazyna Bluff. At the suggestion of P.R. Kyle, it was named by the Advisory Committee on Antarctic Names (2000) after Richard Esser, a member of New Mexico Tech field parties on Mount Erebus in the 1993–94 and 1994–95 seasons, and later a technician in the New Mexico Geochronology Lab at NM Tech, where he has dated many rocks from Antarctica.^[1]
