Popis:	We use 36 MARSIS orbits to extract reflector depths for laterally extensive internal surfaces in the North Polar Plateau and compare the interpolated surface at the bottom of the ice to a prediction of that surface using MOLA data. We find that the prediction and data are in good agreement in terms of regional slope, and may even agree on the finer-scale saddle feature expected based on MOLA. We conclude that the underlying plains are not deflected anywhere beneath the ice deposits, and infer a possibly atypical composition or texture at the top of the Basal Unit in the 270° longitude direction, perhaps indicative of a paleo-dunefield.
