Short summary
Using a drone custom built for high altitude flight (4000–6000 m) we completed repeat surveys of Llaca Glacier in the Cordillera Blanca, Peru. Analysis of high resolution imagery and elevation data reveals highly heterogeneous patterns of glacier change and the important role of ice cliffs in glacier melt dynamics. Drones are found to provide a viable and potentially transformative method for studying glacier change at high spatial resolution, on demand and at relatively low cost.
