And the reader will note that it is practically empty, as even some orangish ground can be seen at the bottom along with some residual ice. This tells us that the above picture is a picture of the Northern Martian hemisphere in the summer, as the “ ice cap “ has largely melted and the crater is empty.

The unfortunate thing, is that I couldn't determine anything from these two photos to support any theory. I even searched on NASA and Hubble websites to see if I could download them in higher resolution so that I could examine them, and I couldn't find a high resolution download.
But I do think the full Mars photo is a pretty picture!
The problem, is when you do zoom in on these low resolution photos, you get to the pixel level really quickly. And that diminishes what you can see. You just can't get close enough to the surface with enough clarity to do much more than guess.
Here's a zoomed in look of the Mars photo, of the 'crater', using Photoshop. You begin to see the pixel outlines. I want to demonstrate that insufficient detail exists in this photo. A lot could be hidden there. It could be just a huge crater, or it could be even be deeper.
If anyone can point me to an actual high resolution download, I would appreciate it.
