Environmental Influences of the Glacieres of the Pryor Mountains, Montana
William B. Vincent


Detailed examination of the glacieres in the Pryor Mountains, Montana revealed several macro-environmental factors which contribute to the freezing microclimates of the caves. The stored-up "cold" of winter and the structure of the cave are traditionally invoked as causes of subterranean ice and are of primary importance. Secondary factors such as the location of the cave, the vegetation zone in which the cave is found, its associated plant cover, and the availability of moisture, also are important.
