Glacier annual balance measurement, forecasting and climate correlations, North Cascades, Washington 1984–2006
North Cascade glacier annual balance measured on 10 glaciers from 1984–2006 yielded mean annual balance (ba) of −0.54 m/a, and −12.38 m cumulatively. This is a significant loss for glaciers that average 30–60 m in thickness, 20–40% of their entire volume. Two observed glaciers, Lewis Glacier and Spi...
