Subsurface Voids, CO2, H2O, Dust cycles Options

[Guest_Steve39_*]

Hello My name is Steve and I had some questions about this image in relation to the current model of current conditions on Mars.

I am new and I understand that some of the greatest minds reside here. I would like to start a discussion on this visible data if possible.

To summarize my position of the image, voids created by CO2 sublimation from beneath. The compression and associated gas release produced the movement of surface features visible. This seems reasonable.

The layering and current surface ice at the polar cap in spite of seasonal dust deposition, post CO2 sublimation, without another source of H2O seems unreasonable.

I would be grateful for any help to reconcile this

Thanks in advance,
Steve
