|The survival kit contains one machete, which doubles as the shoulder rest of the rifle/shotgun. Here Mark is chopping down a small tree that will be used for the construction of a shelter against the wind and cold. The trickiest part of this exercise was knowing that any piece of equipment dropped would disappear into the deep snow. We have only one machete, and only one knife, and only one pistol, so it's very important that these pieces of equipment are handled very carefully. At most times, they would be physically attached to one of the crew members.
