Morphometry of wind tails at the Agilkia landing site. (a and b): perspective views showing the two boulders based on OSIRIS images and DTM data (Jorda et al. 2016). Colors in a encode elevations from – 16 m (blue) to + 15 m (red). Labels in b indicate boulder sizes. The lateral and vertical DTM resolutions are about 35 and 10 cm per pixel, respectively. (c–f): longitudinal and transverse cross sections of the wind tails (and the moat) associated with the two boulders at Agilkia (Tirsch et al. 2017a). The size of the wind tail in profile (ƒ) is at the limit of the DTM resolution which is the reason for the step-like shape of the profile.
