a Mars Orbiter Laser Altimeter (MOLA) topographic map centred on the NW rim of the Hellas basin, showing a depression (blue/violet) in the centre-lower right corner, the cratered highlands (brown-orange) in the upper left corner and the location of the studied outcrop within the red box. The magenta arrow indicates the slope direction of the modern surface. The identified macroforms suggest that the outcrop is broadly cut in the depositional-strike direction, in alignment with regional slope (a). The topographic elevation spans from 1500 m (brown) to −1350 m (white). Bottom right inset shows the regional context. Mars Orbiter Laser Altimeter (MOLA) topographic map centred on the northwestern shoulder of the Hellas basin. Study area indicated by white box. The topographic elevation spans from 4319 m (brown) to −8194 m (white). b High-resolution imaging science experiment (HiRISE) contour lines from HiRISE digital terrain model (1 m/pixel) (HiRISE stereo pairs ESP_055357_1540; PSP_003799_1540) over HiRISE visible image (25 cm/pixel). The Izola outcrop is located at 25.88°S and 54.29°E and faces almost N-S. c 3D view without vertical exaggeration of the Izola outcrop shown in b. HiRISE ESP_055357_1540 (25 cm/pixel) draped on HiRISE digital terrain model (1 m/pixel).
