Map of glacier locations (top) and mass balance changes from 1975-2000 (middle) and 2000-16 (bottom). Mass balance changes are given in metres of water equivalent per year (m w. e. year). Circle sizes are proportional to glacier size and colour is used to indicate whether the glacier is debris-covered (black), debris-free (blue) or terminating in a glacial lake (red).
