Point cloud of the portion of the study area, where the simulation has been run, as generated by Structure from Motion Multiple View Stereophotogrammetry, as well as the position of the RTK-GNSS points and their altitude. The imagery also points out another issue in the valley: the lack of aerial and satellite imagery to monitor change and evolution in the valley because of the important cloud cover. a Perspective view of the point cloud with the tourist track indicated by the red dotted line, managed pathways on the valley talweg and on the fans, allowing a walk to a vantage point on the glacier. b Plan view of the area under cloud cover
