Hi @Kelly_H You beat me to it.
In Photoshop, I can see the "rim" very clearly. But I'm undecided about origin. It looks like the 2 mi of ice is melted there. So the very tippy tops of the mountain range could be poking up... but those articles said those mts were not created by volcanic upheaval but from a folding rift. A rimmed bowl fits with volcanic.... So, maybe your space-hit is a better guess?
That whale's eye is SO vivid. Really, really kewl image.
