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).
The feature is named after the ancient Roman fortress of Tegra in Northeastern Bulgaria.
