“…Plateau polygons did not require a buffer, as they already define the maximum extent of the upper surface of the mound. From these buffers we extracted the mean elevation of pixels from HRSC Digital Terrain Model (DTM) MC‐11 quadrangle data (∼50 m/pixel, Jaumann et al., 2007; Kersten et al., 2018) and the MOLA PEDR (Point Experimental Data Records; Zuber, 1992) point data that fell within each buffer. In situations where multiple MOLA points or HRSC pixels existed within a marginal plains buffer, the mean topographic value was calculated using both datasets in order to mitigate the effect of topographic relief elements that could alter the measured plains elevation.…”

Oxia Planum, the landing site of the ExoMars 2022 rover "Rosalind Franklin", is a clay-rich plain located on the boundary between the ancient, rugged terrain of Arabia Terra (Quantin-Nataf et al., 2021), and the young, smooth plains of Chryse Planitia. Distributed across the Oxia Planum and wider Circum-Chryse region are thousands of kilometer-scale isolated landforms that resemble terrestrial mesas, buttes, hills, and plateaus (Figure 1). The mounds are conspicuous features that can be distinguished by their positive relief, high albedo, and low thermal inertia relative to the surrounding plains. As a widespread geomorphological feature in this highland-lowland transitional area, they are an important component of the geological history of the region, but their morphological variations, origins, and ages were hitherto not well understood. Importantly, several of these mounds are found within the landing ellipse of the ExoMars rover
