This glacier has field-measured summer, winter and annual net balances since 1968, and has been shown to be losing volume at an accelerating rate since the mid-1930s (Kohler and others, 2007).ML consists of amain trunk approximately 4 km in length rising from ∼50m a.s.l. at the terminus to ∼550ma.s.l. at the glacier backwall. It is fed by three smaller
tributary basins and bounded on the south, east and western flanks by steep-sloping mountainous terrain (Fig. 1).
