Next to the gargantuan Airdevronsix icefall is located one more giant icefall - the 920 m wide and 400 m tall Warren icefall.
Just like Airdevonsrix icefalls, Warren icefall has formed in 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 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, verticall 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.

Antarctica is unusual continent, little known to general people and comparatively little investigated. Here are missing numerous kinds of landmarks common in all other continents of the world - but this is compensated by several kinds of landmarks unique to Antarctica.
Some of the most fascinating and awe inspiring natural monuments are waterfalls, or locations where a river abruptly changes its elevation.
