Editing Geography of the Luna Valley

The Luna Valley is probably too large to truly be described as a Valley - since it is actually an area of some 600 square miles of rolling hills, surrounded on three sides by mountain ranges and a sea to the east.

For the last thousand years, the valley had been dominated by a large unnaturally formed glacier that had simply sat on the surface of the valley, covering a good three quarters of the valley. As the stationary glacier was unnaturally formed, it had surprisingly little effect on what it was covering, doing a very good job in preserving things as they were at the point when it magically formed.  Following the impact of the first meteor, the ice has now rapidly melted, having a more detrimental effect, as the entire thing went from solid to liquid in a matter of just days - with flood waters washing away a lot of what had been there before, and carving what had been gentle rolling hills into a highly eroded landscape, dominated by mud, lakes of melt water, or bare rock - with no surviving vegetation to speak of.   

Here and there, ruins from past civilisations can be seen either poking up through the mud, or by some strange twist of luck, standing clear of the erosion and almost as well preserved as if they were still in use.
