Rotten ice should be cleared away with the point of the hammer before the ice piton is driven. Much better support is given the piton if a recess for it is cut into the solid ice. High air temperatures or sun may leave the piton a loose pin in a socket; consequently, the piton should be placed well back in the recess and driven down into the ice at such an angle that a fall will help pull it down into its socket. The piton is more secure at subfreezing temperatures ; therefore shade, storm, or early morning hours may work to advantage. If the piton is frozen in its socket, it will, like a tent stake, hold a direct outward pull better |
