Just like Airdevonsrix icefall, Warren icefall has formed in a location where the giant East Antarctic ice sheet pours (because ice is slow-flowing liquid) in McMurdo Dry Valleys. Here a dolerite sill (intrusion of sturdy rocks) in the Jurassic period broke through the Devonian – Triassic sandstone. This hard rock resists to the force of glaciers and as a result, has formed this giant step with 400 m tall, vertical wall.
Upper rim of falls is at the height of 1,550 m above the sea level. Lower reaches of icefall are not even but in general are some 1150 above the sea level – thus the assumed height of icefall is approximately 400 m.
Airdevronsix icefalls together with Warren falls form one of the most magnificent sights on our planet.
