Short summary
Dry Andean (debris-covered) glaciers and rock glaciers are essential to river runoff by contributing meltwaters in this extremely arid area. We quantify surface lowering for 19 glaciers and 3 debris-covered glaciers, and unchanged velocities for 47 rock glaciers in a ground-truthed and Pléiades satellite imagery based integrative glacier-permafrost study on catchment-scale for 2019-2025. For this period, our findings indicate glacial decline next to permafrost stability.
