Taku Glacier Equilibrium Line Altitude Summer Rise
A key measure of the mass balance of a glacier is the equilibrium line altitude (ELA). Mass balance for non-calving glaciers is the difference between snow accumulation on a glacier and snow and ice loss from the glacier. The ELA is the point at which accumulation equals melting. On temperate alpine glaciers this is the snowline where snow transitions to bare glacier ice. Its elevation at the end of the …
