Conservation is the theme: of the individual, of equipment, and of the environment. Clothing, equipment, and rations are thoroughly discussed, along with the necessity for good expedition behavior. There are chapters on trail techniques, camping for conservation, and basic climbing, and more specialized information on summer snow techniques and winter mountaineering. Reading of topographical maps is included.Detailed illustrations supplement technical material such as knots and use of climbing ropes; and there is valuable appendix material, including checklists of equipment and clothing and recipes.
