3-Glacier Mass Balance Summary

**PROVISIONAL DATA--SUBJECT TO REVIEW**

Cumulative Net Mass Balance

Graphs of cummulative net mass balance.

South Cascade Glacier cumulative net mass balance set to zero at 1965 so that the three glacier records are more easily compared.

Annual Net and Seasonal Mass Balance

Graphs of annual and seasonal mass balances.
