Glaciers and other features around the bay include:

Arrol Icefall

64°35′S 60°40′W. A steep icefall about 3 nautical miles (5.6 km; 3.5 mi) long, originating on the south side of Detroit Plateau, about 8 nautical miles (15 km; 9.2 mi) northwest of Cape Worsley. Mapped from surveys by the Falkland Islands Dependencies Survey (FIDS) (1960-61). Named by the UK Antarctic Place-Names Committee (UK-APC) after the Arrol-Johnston car, which was adapted for use by Ernest Shackleton's Antarctic expedition (1907-09) and was the first mechanical transport used in Antarctica.[3]

Spoluka Point

64°36′40″S 60°21′45″W. An ice-covered point on the southwest side of the entrance to Odrin Bay. Situated 6.9 kilometres (4.3 mi) southwest of Fothergill Point and 4.35 kilometres (2.70 mi) north of Cape Worsley. Formed as a result of the retreat of the glacier featuring Arrol Icefall in the early 21st century. Named after the settlement of Spoluka in Southern Bulgaria.[4]

Akaga Glacier

64°33′50″S 60°27′40″W. A 5.7 kilometres (3.5 mi) long and 2.2 kilometres (1.4 mi) wide glacier situated south of Sinion Glacier and north of the glacier featuring Arrol Icefall. Draining the southeast slopes of Detroit Plateau, and flowing east-southeastwards to enter Odrin Bay. Named after the Bulgar woman ruler Akaga (6th century).[5]

Sinion Glacier

64°32′40″S 60°26′50″W. A 6 kilometres (3.7 mi) long and 3 kilometres (1.9 mi) wide glacier situated southwest of Zaychar Glacier and north of Akaga Glacier. Draining the southeast slopes of Detroit Plateau, and flowing east-southeastwards along the south slopes of Kableshkov Ridge to enter Odrin Bay. Named after the 6th century Bulgar ruler Sinion.[6]

Kableshkov Ridge

A rocky ridge extending 4.5 kilometres (2.8 mi) in WNW-ESE direction, 1.5 kilometres (0.93 mi) wide and rising to 678 metres (2,224 ft).[7] Bounded by Zaychar Glacier to the N, Odrin Bay to the southeast and Sinion Glacier to the SW, and linked to Detroit Plateau to the W. Named after Todor Kableshkov (1851-1876), a leader of the April Uprising of 1876 for Bulgarian independence.[8]

Zaychar Glacier

64°31′25″S 60°20′30″W. A 7.5 kilometres (4.7 mi) long and 2.7 kilometres (1.7 mi) wide glacier. Draining the southeast slopes of Detroit Plateau, flowing between Grivitsa Ridge and Kableshkov Ridge, and entering Odrin Bay 5 kilometres (3.1 mi) northwest of Fothergill Point. Named after the settlement of Zaychar in Southeastern Bulgaria.[9]

A rocky ridge 1.35 kilometres (0.84 mi) long in northwest–southeast direction and 590 metres (1,940 ft) wide, rising to 758 metres (2,487 ft)[10] in the upper course of Zaychar Glacier and linked on the northwest to Detroit Plateau. Situated 2.47 kilometres (1.53 mi) southwest of Batkun Peak in Grivitsa Ridge and 1.73 kilometres (1.07 mi) north of the summit of Kableshkov Ridge. Named after Miki Mikov, radio engineer at St. Kliment Ohridski base during the 1994/95 Bulgarian Antarctic campaign, which set the longterm directions of the Bulgarian Antarctic research.[11]

Batkun Peak

64°30′13″S 60°21′29″W. A peak rising to 881 metres (2,890 ft)[7] high in the southeast foothills of Detroit Plateau. Situated in the west part of Grivitsa Ridge, 9.43 kilometres (5.86 mi) northwest of Fothergill Point and 3.43 kilometres (2.13 mi) north-northeast of Kableshkov Ridge. Surmounting Darvari Glacier to the north and Zaychar Glacier to the south. Named after the settlement of Batkun in Southern Bulgaria.[12]

Grivitsa Ridge

64°30′16″S 60°19′38″W. A mostly ice-free ridge extending 6.4 kilometres (4.0 mi) in northwest-southeast direction, 3 kilometres (1.9 mi) wide and rising to 1,027 metres (3,369 ft) at its northwest extremity.[7] Bounded by Darvari Glacier to the north and Zaychar Glacier to the south, and linked to Detroit Plateau to the northwest. Named after the settlement of Grivitsa in Northern Bulgaria. [13]
