Centropleura Spur ( 71°17′S163°11′E / 71.283°S 163.183°E ) is the southwest spur of a small massif enclosing a cirque, located at the head of Carryer Glacier, 3 nautical miles (6 km) northeast of Mount Jamroga, in the Bowers Mountains, a major mountain range lying within Victoria Land, Antarctica. The geographical feature lies situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare. This spur was the first discovery of Cambrian fossils in this part of Antarctica. [1] [2]
Centropleura Spur consists of the deeply eroded and steeply dipping strata of the Camp Ridge Quartzite and Spurs Formation. [3] Scientific parties visiting this area in 1974–75 and 1981–82 found rare identifiable specimens of the eponymous Middle Cambrian trilobite, Centropleura, and other fossils in an outcrop of the Spurs Formation on Centropleura Spur.

The Dennistoun Glacier is a glacier, 50 nautical miles long, draining the northern slopes of Mounts Black Prince, Royalist and Adam in the Admiralty Mountains of Victoria Land in Antarctica. It flows northwest between the Lyttelton Range and Dunedin Range, turning east on rounding the latter range to enter the sea south of Cape Scott. The coastal extremity of the glacier was charted in 1911–12 by the Northern Party, led by Victor Campbell, of the British Antarctic Expedition, 1910–13. The geographical feature lies situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare.

The seaward end was first sighted in February 1911 from the Terra Nova, under Lt. Harry L.L. Pennell, RN, and was subsequently named "Bowers Hills" in honour of Henry Robertson Bowers who perished with Captain Robert Falcon Scott on their return from the South Pole in 1912. The mountain range is one of the most extensive topographical features within Victoria Land.
