John Wright works on the snow bridge above a crevasse named Mongo which the South Pole traverse team discovered and later filled with snow. An over-ice traverse route is being explored as an alternative to flying supplies to the South Pole. Every crevasse discovered in the route must be exposed and filled so tracked vehicles can safely pass over them. This crevasse measured 32 feet wide, 82 feet deep with a snow bridge 25 foot deep.
