Zeus Ridge
Zeus Ridge () is a heavily crevassed, steep-sided, ice-covered ridge, the main part rising over 1,675 m, extending northwest from Mount Francais between the Achaean Range, Achaean and Trojan Ranges in central Anvers Island, in the Palmer Archipelago. Surveyed by the Falkland Islands Dependencies Survey (FIDS) in 1955 and named by the United Kingdom Antarctic Place-Names Committee (UK-APC) for Zeus, the supreme Olympian deity. It was first climbed in 2019 as part of a traverse of the massif. References Ridges of Graham Land Landforms of the Palmer Archipelago {{AnversIsland-geo-stub ...

Crevasse
A crevasse is a deep crack, that forms in a glacier or ice sheet that can be a few inches across to over 40 feet. Crevasses form as a result of the movement and resulting stress associated with the shear stress generated when two semi-rigid pieces above a plastic substrate have different rates of movement. The resulting intensity of the shear stress causes a breakage along the faces. Description Crevasses often have vertical or near-vertical walls, which can then melt and create seracs, arches, and other ice formations. These walls sometimes expose layers that represent the glacier's stratigraphy. Crevasse size often depends upon the amount of liquid water present in the glacier. A crevasse may be as deep as 45 metres and as wide as 20 metres. by |
