Amazonian thermokarst in Danielson crater, Arabia Terra region, Mars

This paper describe the possible ice-related landforms observed within Danielson crater which is centered at about 81N and 3531E, in the region of southwestern ArabiaTerra about 800km South of Becquerel crater. A morphological survey of the study area through an analysis of the available Mars images was performed. The features of the landforms were investigated through an integrated analysis of Reconnaissance Orbiter (MRO) High Resolution Imaging Science Experiment (HiRISE) and Context Camera (CTX) data. Landforms interpreted as due to thermokarst processes, resembling similarly ice-related landforms found both in the cold-climate non glacial regions of Earth, and putatively in other areas of Mars, was observed. These landforms are attributed to the presence of ground ice/ice melting processes reflect significant climatic changes and different climatic conditions than those existing now. Moreover, they appear to display young erosional age, suggesting that are probably young, probably of Amazonian age.
