Dry Ice Bomb Craters on Mars?

Dry Ice Bomb Craters on Mars?

The main idea here is that Mars used to be covered by carbon dioxide and that throughout the geological history of Mars (particularly if there were active sources of geothermal heat beneath the surface), as most of that dry ice sublimated off and escaped the planet's atmosphere, that the sublimation explosions would have created many many of the craters commonly observed on the surface of Mars. The phase diagram (Mars atmosphere pressure is in millibars) seems to support this hypothesis.

Look what can be accomplished with a small cube of dry ice, and then imagine the damage a mere acrefoot on Mars could do.
