Quantitative morphological metric extraction results and numerical simulation results. A. Spatial distribution of DAF across the study area, overlaid on a shaded relief base map derived from DTEEC_033165_2195_032875_2195_A01 (26). Colors represent specific DAF values indicated by the color bar on the bottom right. The MBT boundary is shown as a black dashed line. B. Schematic diagram defining the key morphological feature of MBT. The curve represents the terrain tangent of MBT. The yellow shaded areas indicate depression. The dashed line represents the depression threshold elevation (DTE) (see SI Appendix). C-E. HiRISE images of three local MBT in the study area. All three images share the same scale-bar. F-H. Detrended observed elevation data for three MBT areas shown in C-E, respectively (SI Appendix, Fig. S3). The white contour lines, which correspond to DTE values, outline the depression areas. Colors indicate elevation value using a color bar shown to the right of H. The I-K. Simulation results with increasing maximum stone movement rate (𝑣max): 3.25 mm/cycle (I), 3.40 mm/cycle (J) and 3.90 mm/cycle(K).Colors represent the simulated elevation using a common color bar shown to the right of K. -- astro-ph.EP
