Glaciers in the Hunza catchment (Karakoram) have been nearly in balance since the 1970s
With the help of old US reconnaissance imagery new mass balance insights in the Hunza River basin (Central Karakoram) could be retrieved.
Previous geodetic estimates of glacier mass changes in the Karakoram have revealed balanced budgets or a possible slight mass gain since the year ∼ 2000. We used old US reconnaissance imagery and could show that glaciers in the Hunza River basin (Central Karakoram) experienced on average no significant mass changes also since the 1970s. Likewise the glaciers had heterogeneous behaviour with frequent surge activities during the last 40 years [Paper].
