Description :
Glacier mass balance is estimated for South Cascade Glacier and Maclure Glacier using a one-dimensional regression of mass-balance with altitude as an alternative to the traditional approach of contouring mass balance values. Two different regression equations were examined. The results point to dominant effect of the gradient of mass balance with altitude of alpine glaciers compared to transverse variations. The number of mass balance measurements required appears to be scale invariant for small glaciers and 5 to 10 stakes are sufficient.
