Cape Géodésie
Cape Géodésie () is a low, ice-covered point marked by prominent rock outcrops at its northeast end, lying northwest of the mouth of Astrolabe Glacier Astrolabe Glacier is a glacier wide and long, flowing north-northeast from the continental ice and terminating at the coast in a prominent tongue at the east side of Geologie Archipelago. It was first sighted in 1840 by the French expedition u ..., Antarctica. It was photographed from the air by U.S. Navy Operation Highjump, 1946–47. It was charted by the French Antarctic Expedition, 1951–52, and so named by them because of the extensive geodetic program undertaken in this region, particularly in the Geologie Archipelago close offshore.

Outcrops
An outcrop or rocky outcrop is a visible exposure of bedrock or ancient superficial deposits on the surface of the Earth. Features Outcrops do not cover the majority of the Earth's land surface because in most places the bedrock or superficial deposits are covered by soil and vegetation and cannot be seen or examined closely. However, in places where the overlying cover is removed through erosion or tectonic uplift, the rock may be exposed, or ''crop out''. Such exposure will happen most frequently in areas where erosion is rapid and exceeds the weathering rate such as on steep hillsides, mountain ridges and tops, river banks, and tectonically active areas. In Finland, glacial erosion during the last glacial maximum (ca. 11000 BC), followed by scouring by sea waves, followed by isostatic uplift has produced many smooth coastal and littoral outcrops. Bedrock and superficial deposits may also be exposed at the Earth's surface due to human excavations such as quarrying and build ...

Astrolabe Glacier
Astrolabe Glacier is a glacier wide and long, flowing north-northeast from the continental ice and terminating at the coast in a prominent tongue at the east side of Geologie Archipelago. It was first sighted in 1840 by the French expedition under Captain Jules Dumont d'Urville, although no glaciers were noted on d'Urville's chart of this coast but a formidable icy dike with perpendicular flanks of 37.7 m high according to the joined plate, corresponding to the glacier tongue. The glacier was photographed from the air by U.S. Navy Operation Highjump in January 1947. It was charted by the French Antarctic Expedition, 1949–51, and named after d'Urville's flagship, the ''Astrolabe''. The Astrolabe Glacier Tongue () is a prominent glacier tongue about wide and long, extending northeast from Astrolabe Glacier.
