Annual net balance of North Cascade glaciers, 1984-94
Abstract Annual net balance eight North Cascade glaciers during the 1984-94 period has been determined by measurement of total mass loss firn and ice melt and ice melt and, residual snow depth at the end of the Summer season. Overall spatial density of measurment points is 200 points km −2 . Mean an...
