Patterns of martian glacial deformation: Implications for glacio-geology, internal structure, and regional climate

Viscous Flow Features (VFF) are widespread in the martian mid-latitudes and indicative of near-surface ice deposits. Their distribution morphology hint at regional history deposition ablation, as well changes surface temperature. Here we interrogate deformation a type VFF, Lobate Debris Apron (LDA), located eastern Hellas region, from its morphology, discussing implications it poses for internal structure climate variability. Our observations integrate data Colour Stereo Surface Imaging System (CaSSIS), SHAllow RADar (SHARAD), Context Camera (CTX), High Resolution Science Experiment (HiRISE), Mars Orbiter Laser Altimeter (MOLA). Morphological observations, spectral analysis characteristic wavelengths, stability place constraints on dynamics deposit. We discuss contrasting hypotheses origin different structures, including possibility gelifluction addition to glacial creep. results provide guide interpret patterns VFFs light structure, history, underlying topography.
