Positive-Relief Feature on South Polar Layered Deposits

A Curious Case of Positive-Relief
This observation captures a curious, fractured feature on the South Polar layered deposits: is this an active feature? We saw this in a much earlier image, but it was very hard to find changes with such an extreme difference in lighting direction. This will be part of a series to reproduce the lighting and compare any changes.
