Ice and water Mixed on Mars

There are some interesting observations on this photo. The first is that it appears that there may be ice, the whiter and may be floating white parts of the picture. This includes the outer shoreline that looks like it too is iced.

The reflective areas look like still water. Thorough we cannot see into the water.

The water is on a slow spiral. If you look carefully we can see that the liquid water – if that is what it is – spirals slowly out from that raised hub part.

What is that hub raise like a dome in the centre?I have no idea,. and wonder if it is not raised but a depression and water is going down. But possibly the raised hub is an up-flow of ground water. It does not look like it, however.
