    Description

    Altitude, in broad subdivisions, exerts recognized and well-understood effects on climate. Aspect further modifies the altitudinal influence. Many publications have dealt with the interrelations of these geographic factors with climate and life zones or have discussed variations of individual weather elements as influenced by local altitude and aspect differences and the resultant effects on vegetation types, frost belts, thermal belts, phenology of plants, water resources, and agricultural economics in mountainous countries. Such variations have never before been systematically investigated, however, to determine their relation to forest-fire control, which in the northern Rocky Mountain region is the vet-unsolved, problem basic to the successful practice of forestry.
