In reply to mockerkin:
"*summer* rain... which will become ice"
No it won't. Even if it did, the relationship between total seasonal precipitation and the water content of voids and cracks is very complex. distribution of rainfall is much more important. Also, rare summer freezing is only going to be made rarer by warm humid conditions.
"Then the mountain plants will arrive..."
Are they going to grow in some magical soil that has been created in <5-10 years? It's good to know any damage we've already done is so easily reversible, although it does rather negate your punchline.
Good imagination though, you could probably make a Hollywood disaster movie out of a WI meeting.
