“Lützelau rockfall” on southern slope of the mountain Rigi, shaded relief generated from combined high-resolution bathymetry data and airborne laser scanning data (swisstopo DTM-AV) for areas above the lake (see Fig. 1 for location). Inset shows positions of identified debris cones and escarpment. Note that shading is scaled differently (underwater areas appear steeper) for bathymetry data and DTM-AV in order to improve the visibility of features
