Broken Martian ice sheets?

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on August 11, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The picture was what the camera team call a “terrain sample,” which usually means the picture was taken not as part of any specific research request, but because there was a gap in the camera’s schedule, and in order to maintain the camera’s temperature the team then picks something to fill that gap.
Because of the relative randomness of such pictures, they sometimes show little of immediate interest. More often than not, however, the camera team chooses well, and snaps something cool.
In this case they achieved the latter. The white dot on the overview map above marks the location, inside the 2,000-mile-long northern mid-latitude strip I dub glacier country. Everything in this region seems covered with glacial and ice debris, and this picture is no different. Rather than a glacier however we have what looks like a broken ice sheet, surrounded by that utterly unique and as-yet unexplained Martian geological feature dubbed brain terrain.
