Livingston Island is an Antarctic island in the South Shetland Islands, Western Antarctica lying between the islands of Greenwich and Snow. This island was the first land discovered south of 60° south latitude in 1819, and the name Livingston, although of unknown derivation, has been well established in international usage since the early 1820s.
Mount Bowles is an ice-covered mountain 822 metres (2,697 ft) high, the summit of Bowles Ridge in the central part of eastern Livingston Island in the South Shetland Islands, Antarctica. It is situated south of Vidin Heights and north of Mount Friesland, Tangra Mountains to which it is linked by Wörner Gap.
Great Needle Peak is the summit of the central Levski Ridge in Tangra Mountains on Livingston Island, Antarctica. Rising to 1,679.5 m, it is the third highest peak of both the mountains and the island after Mount Friesland (1700.2 m) and St. Boris Peak (1685 m). Great Needle Peak surmounts Huron Glacier and its tributary draining Devnya Valley to the north, Magura Glacier to the east, Srebarna Glacier to the south, and Macy Glacier to the southwest.
Bowles Ridge is bounded by Kaliakra Glacier and Struma Glacier to the north, by Perunika Glacier to the west and southwest and by Huron Glacier to the southeast and east. It is linked to Friesland Ridge of the Tangra Mountains by Wörner Gap, to Hemus Peak by Dimov Gate, and to Melnik Ridge by Yankov Gap. The ridge is crossed by Omurtag Pass and Pirdop Gate.
Kaliakra Glacier is a glacier in northeastern Livingston Island, Antarctica extending 3.8 nautical miles in east-west direction and 4.3 nautical miles in north-south direction, and situated southeast of Saedinenie Snowfield, southwest of Panega Glacier, north of Struma Glacier and upper Huron Glacier, and northeast of Perunika Glacier. It is bounded by Melnik Ridge and Bowles Ridge to the south, by Hemus Peak, Gurev Gap, Gleaner Heights, Elhovo Gap, Leslie Hill, Leslie Gap and Radnevo Peak to the west, and Miziya Peak and Samuel Peak to the north. The glacier drains eastwards into Moon Bay south of Perperek Knoll and north of Sindel Point.
Struma Glacier is a glacier in eastern Livingston Island in the South Shetland Islands, Antarctica situated south of lower Kaliakra Glacier and north of Huron Glacier. Bounded by Melnik Ridge to the north, Yankov Gap to the west and Bowles Ridge to the south, it is 4.8 km long and 1.5 km wide, and flows eastwards into Moon Bay south of Sindel Point and north of Elemag Point.
Perunika Glacier is an 8 km long and 3 km wide (average) roughly crescent-shaped glacier in eastern Livingston Island in the South Shetland Islands, Antarctica situated east of Pimpirev Glacier, south of Saedinenie Snowfield, southwest of Kaliakra Glacier, west of Huron Glacier, and north of Balkan Snowfield and the head of Huntress Glacier.
The feature takes its name from Mount Bowles.
The ridge is centred at Coordinates: . It was mapped by the British in 1968 and surveyed by Bulgarian topographic surveys in 1995/6 and 2004/5 with mapping in 2005 and 2009.
A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.

Friesland Ridge 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 by the Bulgarian survey Tangra 2004/05.
Levski Ridge is the central ridge of the Tangra Mountains, Livingston Island. Its summit, Great Needle Peak rises to 1,680m and is the second highest summit of the island after Mount Friesland.
Lyaskovets Peak is the easternmost peak of Friesland Ridge in the Tangra Mountains, eastern Livingston Island and has an elevation 1,473 m. The peak is bounded by Catalunyan Saddle to the west and Shipka Saddle to the east and is heavily glaciated and crevassed, with precipitous western, southern and eastern slopes. It surmounts Huron Glacier to the northwest and northeast, and Macy Glacier and Brunow Bay area to the south. Its northern offshoot forms Zograf Peak, and is linked to Lozen Nunatak, Erma Knoll and Aheloy Nunatak in Huron Glacier.
Maritsa Peak rises to 560 m in eastern Bowles Ridge on Livingston Island in the South Shetland Islands, Antarctica. It has precipitous rocky south slopes, and is situated on the west side of Pirdop Gate, surmounting Huron Glacier to the south and Struma Glacier to the north. The peak is "named after the Maritsa River in Bulgaria."
Pliska Ridge is a three-peaked ridge rising to 667 m in eastern Livingston Island in the South Shetland Islands, Antarctica.
