Tegra Nunatak

Tegra Nunatak (Bulgarian: нунатак Тегра, ‘Nunatak Tegra’ \'nu-na-tak 'te-gra\) is the mostly ice-free rocky ridge extending 2.6 km in east–west direction and 700 m wide, rising to 1075 m[1] at the west extremity of Elgar Uplands in northern Alexander Island, Antarctica. It surmounts Delius Glacier to the southeast and Nichols Snowfield to the north and west. The nunatak was visited on 30 January 1988 by the geological survey team of Christo Pimpirev and Borislav Kamenov (First Bulgarian Antarctic Expedition), and Philip Nell and Peter Marquis (British Antarctic Survey).
