Abstract

Glaciers of Glacier National Park, Mont., the program for their measurement, and findings from measurements and mappings are discussed. Recent trends in temperature and precipitation in Montana are analyzed and their relation to glacier changes are noted. The growth of Glacier Park glaciers in recent years, after over 40 years of recession, appears to be related to the recent cool and relatively wet years in the northern Rocky Mountain Region. It is pointed out that this trend toward cool, wet weather coincides with Willett's tentative forecast [6] based on extrapolation of sunspot–climate relationships.
