Coal Nunatak

Coal Nunatak (72°7′S 68°32′W / 72.117°S 68.533°W / -72.117; -68.533) is a flat-topped rock mass with steep cliffs facing south, standing 2 nautical miles (4 km) southwest of Corner Cliffs on the southeast corner of Alexander Island, Antarctica. Lincoln Ellsworth first noted it from the air on November 23, 1935, and mapped it from photos obtained on that flight by W.L.G. Joerg. Observed from the northwest (the direction from which Ellsworth photographed this nunatak), only the summit protrudes above the coastal ice, and it was uncertain whether this was a peak on Alexander Island or an island in George VI Sound. Its true nature was determined by the Falkland Islands Dependencies Survey (FIDS) who visited and surveyed this nunatak in 1949. So named by FIDS for exposures of thin lenses of coal occur there.
