Nattriss Head, a small but prominent rock headland, marks the south side of the entrance to Drygalski Fjord. Like the fjord, it was charted by Filchner's expedition. It was originally named Nattriss Point for E.A. Nattriss, shipping officer to the Discovery Committee, following survey by Discovery Investigations personnel in 1927. It was later renamed Nattriss Head to avoid confusion with Nattriss Point on Saunders Island in the South Sandwich Islands.[3]
Trendall Crag is a mountain crag overlooking the north side of the fjord at the southeast end of South Georgia. Surveyed by the South Georgia Survey (SGS) from 1951 to 1957 by a research group led by English explorer Duncan Carse, it was named after Alec Trendall, an English geologist who took part in the SGS expedition. The crag has an elevation of 1,005 metres (1.005 km).[6]
