Additional emergency equipment.—A light hand ax and sheath is considered essential by many experienced winter mountaineers, for it enables one to provide adequate shelter and fire wherever sufficient timber can be found. It is omitted from the list of advisable equipment
because the tent and stove are adequate below, as well as above, timberline (see p. 76). A light shovel is convenient for making camp in addition to its emergency value for avalanche rescue; many also list it as essential. Long trips require boot wax, additional flashlight cells, and a small packet of repair parts for the stove.
