Livingston Island in the context of "Tangra Mountains"

The Veleka (Bulgarian: Велека [vɛˈlɛkɐ], Turkish: Kocadere [koˈd͡ʒadeɾe]) is a river in the very southeast of Bulgaria, as well as the very northeast of European Turkey. It is 147 km long, of which 108 km lie in Bulgaria and 25 km are in Turkey. It flows into the Black Sea at the Bulgarian village of Sinemorets. Veleka Ridge on Livingston Island in the South Shetland Islands, Antarctica is named after the river.

Veleka Ridge is a predominantly ice-free ridge extending 3 km between Charity Glacier in the north and Botev Point in the south, and 1.3 km wide, in the southwest extremity of Friesland Ridge, Tangra Mountains on Livingston Island in the South Shetland Islands, Antarctica. The ice-free surface area of the ridge and the adjacent Arkutino Beach is 468 hectares (1,160 acres). Surmounting Tarnovo Ice Piedmont to the east, Charity Glacier to the north, Arkutino Beach to the west, and Barnard Point and Botev Point to the southwest and south respectively. The ridge's summit Veleka Peak rises to 538 m in its north extremity.

The ridge was named after the Veleka River in southeastern Bulgaria.

The Tundzha (Bulgarian: Тунджа [ˈtund͡ʒɐ]; Turkish: Tunca [tund͡ʒa]; Tonsus in antiquity) is a river in southeastern Bulgaria and northwesternmost Turkey, a left tributary of the Maritsa. With a length of 390 km, of which 350 km are in Bulgaria, it is Maritsa's longest tributary, though in terms of discharge it is second after the Arda. Tundzha Glacier on Livingston Island in the South Shetland Islands, Antarctica is named after Tundzha River.

Plana (Bulgarian: Плана) is a mountain range in western Bulgaria with an altitude of 1,337 meters above sea level. It is part of the Srednogorie mountain system that from west to east includes the mountain ranges of Greben, Zavalska Planina, Viskyar, Lyulin, Vitosha, Plana and Sredna Gora. Plana Peak in Tangra Mountains on Livingston Island, Antarctica is named after it.

Charity Glacier (62°44′S 60°20′W / 62.733°S 60.333°W / -62.733; -60.333) is a glacier on Rozhen Peninsula, Livingston Island in the South Shetland Islands, Antarctica draining the southwest slopes of St. Methodius Peak in Tangra Mountains, and flowing west-southwestwards into False Bay north of Barnard Point, between Zagore Beach and Arkutino Beach.

The glacier was named by the UK Antarctic Place-names Committee in 1958 after the brig Charity (Capt. Charles H. Barnard), one of a fleet of American sealers from New York which visited the South Shetland Islands in 1820–21, operating mainly from Yankee Harbor, Greenwich Island. The Charity also visited the islands the following season.

Botev Point (Bulgarian: нос Ботев, romanized: nos Botev, IPA: [ˈnɔz ˈbɔtɛf]) is the south extremity of both Rozhen Peninsula and Livingston Island in the South Shetland Islands, Antarctica formed by an offshoot of Botev Peak in the Veleka Ridge of Tangra Mountains.

The feature is named after Hristo Botev (1848–1876), poet and leader of the Bulgarian liberation movement.

Friesland Ridge (Hrebet Frisland \'hre-bet 'fris-land\) is a ridge on Livingston Island in the South Shetlands, part of the Tangra Mountains. The summit, Mount Friesland, which rises to 1,700 metres (5,600 ft), is the northwesternmost of the ridge's six main peaks. Its elevation was estimated at 1,684 metres (5,525 ft) by a 1995/96 Bulgarian survey; the present figure was produced by a 2003 Australian GPS survey, and closely matched (as 1,702 metres (5,584 ft)) by the Bulgarian survey Tangra 2004/05.

The local ice relief is subject to changes, causing variations in the mountain peaks’ elevation. According to a Bulgarian GPS survey by D. Boyanov and N. Petkov the elevation of Mt. Friesland was 1,693 metres (5,554 ft) in December 2016, making the peak lower than the adjacent St. Boris Peak (the latter's northernmost ice formation ‘The Synagogue’ rising to 1,699 metres (5,574 ft)) at that time.

Arkutino Beach (Bulgarian: бряг Аркутино, romanized: bryag Arkutino, IPA: [ˈbrʲak ɐrˈkutino]) is a beach extending 1.8 km on the east coast of False Bay, Livingston Island, Antarctica. The beach is situated on Rozhen Peninsula, and is bounded by Charity Glacier to the north, Barnard Point to the south, and Veleka Ridge to the east. It is snow-free in the summer. The ice-free surface area of the beach and the adjacent Veleka Ridge is 468 hectares (1,160 acres).

The feature was named after the coastal lagoon of Arkutino in southeastern Bulgaria.
