Tangra Mountains

Tangra Mountains (in Bulgarian Тангра планина, 'Tangra planina' \'tan-gra pla-ni-'na\) (62°40′00″S 60°06′00″W) form the principal mountain range of Livingston Island in the South Shetland Islands, Antarctica. The range had been nameless until 2001, when it was named after Tengri (Bulgarian Tangra), "the name of the ancient Bulgarian god."

Tangra Mountains are 32 kilometres (20 mi) long between Barnard Point and Renier Point, 8.5 kilometres (5.3 mi) wide, and are bounded by Moon Bay and Huron Glacier to the north, Huntress Glacier to the northwest, False Bay to the west, and Bransfield Strait to the southeast, and is linked to Bowles Ridge by Wörner Gap, and to Pliska Ridge by Nesebar Gap. The mountain is divided in three principal ridges: Friesland Ridge in the west, Levski Ridge in the centre, and Delchev Ridge in the east.

The peaks and slopes of Tangra are heavily glaciated, and drained by the glaciers Huron, Huntress, Ruen Icefall, Peshtera, Charity, Tarnovo Ice Piedmont, Prespa, Macy, Boyana, Srebarna, Magura, Dobrudzha, Ropotamo, Strandzha, Pautalia, Sopot Ice Piedmont, and Iskar.

Camp Academia in the northwestern foothills of Zograf Peak is the perfect gateway to central Tangra Mountains via Catalunyan Saddle (1260 m) to the south and Lozen Saddle (437 m) to the east. Catalunyan Saddle was occupied by a bivouac of the Tangra 2004/05 Exploration team on 14–16 December 2004.
