Bowles Ridge

Bowles Ridge (Bulgarian: хребет Боулс, romanized: hrebet Bouls, IPA: [ˈxrɛbɛd ˈbɔuɫs]) is the central ridge of eastern Livingston Island. The ridge extends 6.5 km in the east-west direction and is 1.5 km wide. The summit of the ridge is Mount Bowles which rises to 822m and is located 9.77 km northwest of Great Needle Peak, 6.08 km north by west of Mount Friesland, 8.77 km east-northeast of St. Kliment Ohridski base and 9.25 km south by west of Miziya Peak.

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.

The feature takes its name from Mount Bowles.
