Hi, restore49.
As I understand it, a Tucker Sno-cat had already passed over that area which was basically a snow bridge over the crevasse. The bridge was strong enough to support the weight of the Sno-cat but collapsed under the weight of the LGP D8 which was maybe 4 times heavier. In fact, the Sno-cat passing over it may also have weakened the snow bridge somewhat.
Again as I understand it, the expedition in Greenland devised a way of detecting crevasses BEFORE anybody fell into them and that technology was also sent to Antarctica.
Just my 0.02.

Deas,
My research showed the Greenland crevasse detecting equipment was brought down there about 1956 along with the guy who developed it. He actually was called by radio up in Greenland and found himself talking to the Chief of Naval Operations if I remember right. And he was only a sergeant! Needless to say, he agreed to go down the Antarctica!
And another tidbit about this accident was that Linda took Mary Ann's blade down with her per "Scotty."
