Fred, Thanks for the information. As I mentioned in another post, I am probably still in a bit of shock from the "bug-out" (I am not a fire-fighter!) with being so close to the "freight-train" sound effect of the advancing fire, and from seeing the very-burnt landscape while it was still smoldering and with hand-crews and water-drops still being used on hot-spots. And the "officials" have already addressed the erosion concern in the local paper. I was using the term "moonscape" in a descriptive sense only, not in a technical sense.
