That looks like a heavily impacted snow/ice field that has been melting. I’ve seen year long snow fields like that in the northern north west territories.

The honeycomb pattern forms when the lighter snow melts in the sun as the melt water flows around the older and harder snow/ice. It gathers at a low point and as the water warms up it melts the surrounding harder snow/ice forming a bowl like depression.

This is mars so if that’s ice it’s probably mixed with sand and dust which can insulate the ice, but the lack of air pressure and sunlight probably does something funky with evaporation rates.
