Bogdan Ridge (Rid Bogdan \'rid 'bog-dan\) is a conspicuous rocky ridge of elevation 440 m forming the northeast extremity of Breznik Heights, Greenwich Island in the South Shetland Islands, Antarctica. The ridge extends 1.3 km westwards from Santa Cruz Point and surmounts Gruev Cove to the south.

Breznik Heights

Breznik Heights rises to over 600 m in the southeast part of Greenwich Island. They extend 12 km between Santa Cruz Point in the northeast and the base of the moraine spit of Provadiya Hook at the mouth of Yankee Harbour in the southwest. The heights are ice-covered except for limited precipitous areas such as those at Oborishte Ridge, Ephraim Bluff, Viskyar Ridge and Bogdan Ridge.

Greenwich Island island

Greenwich Island is an island 24 km (15 mi) long and from 0.80 to 9.66 km wide, lying between Robert Island and Livingston Island in the South Shetland Islands. Surface area 142.7 square kilometres (55.1 sq mi). The name Greenwich Island dates back to at least 1821 and is now established in international usage.

South Shetland Islands A group of islands north of the Antarctic Peninsula

The South Shetland Islands are a group of Antarctic islands with a total area of 3,687 square kilometres (1,424 sq mi). They lie about 120 kilometres (75 mi) north of the Antarctic Peninsula, and between 430 kilometres (270 mi) to 900 kilometres (560 mi) south-west from the nearest point of the South Orkney Islands. By the Antarctic Treaty of 1959, the islands' sovereignty is neither recognized nor disputed by the signatories and they are free for use by any signatory for non-military purposes.

The feature is named after Bogdan Peak, the summit of Sredna Gora Mountain in Central Bulgaria.

Sredna Gora mountain range

Sredna Gora is a mountain range in central Bulgaria, situated south of and parallel to the Balkan mountain range and extending from the Iskar River to the west and the elbow of Tundzha north of Yambol to the east.

Geographic coordinate system Coordinate system

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.

Benkovski Nunatak

Benkovski Nunatak is a rocky peak of elevation 450 m projecting from the ice cap of Greenwich Island in the northeast extremity of Breznik Heights. Situated 920 m west-southwest of Bogdan Ridge, and 690 m north of Parchevich Ridge. Overlooking Gruev Cove to the east. Bulgarian topographic survey Tangra 2004/05.

López Nunatak

López Nunatak is a steep-sided granitic nunatak, 275 metres (900 ft) high, forming the northern extremity of the Breznik Heights, Greenwich Island in the South Shetland Islands, Antarctica and overlooking Fuerza Aérea Glacier to the south-southwest, and Ash Point and the Chilean Captain Arturo Prat Base to the northwest.
