In this observation, it looks like we can view a couple of erosional windows in the scalloped (ice-rich) unit. This area is a good place for imaging samples of the contact to understand the deposition and erosion. We can also sample boulders and polygons at full resolution. Expansion and contraction of underground ice is responsible for the polygon formation.
