Levski Ridge in the context of "Tangra Mountains"

Plana Peak (Bulgarian: връх Плана, romanized: vrah Plana, IPA: [ˈvrɤx ˈpɫanɐ]) is a mostly ice-covered peak on the Levski Ridge, Tangra Mountains, Livingston Island in the South Shetland Islands, Antarctica. Surmounting Huron Glacier to the north and its tributaries to the east and west. First ascent by D. Boyanov, N. Petkov and A. Shopov on 8 January 2015. The peak is named after Plana Mountain in Western Bulgaria.

Macy Glacier is a 3.7 nautical miles (6.9 km; 4.3 mi) long and 1.4 nautical miles (2.6 km; 1.6 mi) crescent-shaped glacier on the southern slopes of the Tangra Mountains, Livingston Island in the South Shetland Islands, Antarctica. The glacier is bounded by Friesland Ridge to the northwest, Levski Ridge to the northeast and Peshev Ridge to the southeast, and flows southwestwards into the head of Brunow Bay.

The feature was named by the UK Antarctic Place-names Committee in 1958 for Robert Macy, Master of the brig Aurora, one of the fleet of American sealers from New York which visited the South Shetland Islands in 1820–21.
