Figure 2 . Google Earth images showing rock glaciers of four different types and their spatial connections to the upslope units. (a) shows a debris-mantled slope-connected rock glacier (DMS-RG) in orange (ID: wkl234). (b) focuses on a glacier-connected rock glacier (G-RG) in green (ID: wkl059). The cyan polygons are glaciers outlined by the GLIMS dataset and the feature in between is recognized as a debris-covered glacier. (c) presents a glacier forefield-connected rock glacier (GF-RG) in purple (ID: wkl008). Note that the GF-RG disconnects from the upslope glacier in cyan, whereas the G-RG in (b) is in continuation of the upslope debris-covered glacier. (d) displays a talus-connected rock glacier in pink (ID: wkl117), from which the upslope talus can be observed.
