Pettus Glacier (63°48′S 59°04′W) is a narrow deeply entrenched glacier 9 nautical miles (17 km; 10 mi) long, which flows north from Ebony Wall into Gavin Ice Piedmont between Poynter Hill and Tinsel Dome, Trinity Peninsula, Antarctica.




Location



Pettus Glacier is in Graham Land in the Trinity Peninsula, which is the tip of the Antarctic Peninsula.
The glacier flows north from Ebony Wall on the side of the Detroit Plateau to the Gavin Ice Piedmont, which lies to the south of Bone Bay and east of Charcot Bay.
It passes Ivory Pinnacles, Poynter Col and Poynter Hill on its west side, and Aureole Hills and Tinsel Dome on its east side.

An ice-covered col of elevation 1,000 metres (3,300 ft) high extending 950 metres (3,120 ft), and linking Ivory Pinnacles to the north to Detroit Plateau to the south.
Surmounting Pettus Glacier to the east.
Named after the settlement of Ohoden in Northwestern Bulgaria.
