Pitted Mounds
Are unlikely to be impact craters.
Some mounds are heavily modified craters, but these preserve the pits and are grouped in diagnostic clumps and chains.
Probably phreatic cones of one sort or another.
Either hot magma interacting with ice/water/CO2 or pure CO2 escape without heat.
Many of the craters you've shown in this string of images are modified impacts, with various internal forms perhaps related to ice movement and soil creep. This image is different.
