This area defines the upper end of the Wright Valley. It is the most spectacular example of how the Transantactic Mountains hold back the East Antarctic Plateau ice and of how the dramatically ice spills over into the upper Dry Valleys. The Upper Wright Glacier is interesting because of it's smooth, flat-top, rounded shape as it fills the giant cirque. The ice is worn smooth by the katabatic (heavy because of such cold air off the continent) winds that plummet off the plateau as dramatically as the icefalls.
The Labrinyth, a maze of large (every thing in Antarctica is large) channels, might have been formed by the outwash flood from an ancient subglacial lake.
The Airdevronsix Icefall was named after some military aviation group that supported the US Antarctic Program back in the early years of the fifties and sixties (if anyone has more info, let me know!). As I recall from a map, this icefall is something like ten miles across.
