even strayan bases do expeditions out onto the ice plateau and raaf has an ice airstrip there, and even qantas used to do tourist flights that went beyond the coast, so if there is an ice-wall it's not near the edge. anyway, its easier to immigrate to argentina and eat bbq and beers, than to to keep sailing down to antarctica, cross the flat ice bit, then somehow find the magical inner-earth hole, and set up there with the dinosaurs and ayliems.
