ESP_011844_1855 - icy/muddy terrain and flow features possibly

HiRISE ESP_011844_1855 is quite an interesting observation featering a portion of southwest Arabia Terra (one of the areas with regional methane and water vapor concentrations). The lower plains showing some nice small scale fresh rampart craters suggesting ice or even mud very near the surface. Also there seems to be some horizontal flow like features in the second cutout among another rampart crater.

Maybe this observation is worth a closer inspection
