Fig. S3: Geomorphological analysis of gullies on the central peak of Lyot Crater, Mars

Area 3 gully 3a with transects (white) showing volume removed measurement bank perimeters (colour). Transects: #100: transect showing about 4 m of alcove incision into the rock; #87: alcove branching; #74: main channel, channel fill material, and side terraces; #51: lots of channel fill dunes or fracturing (Fig. 7, main text, shows a close-up); #19: very tiny channels indistinguishable in the profile from surrounding ground patterns, very thin apron at this point, if any. North is up.
