I predict that Mount St Helens will return to the way it was before the eruption, because plants and animals and trees are coming back to live there. About the part of the mountain that fell of in the big eruption, I believe that someday, either the peice that remained in the eruption will blow off in another eruption, the cause being it would be the same, but it would be a smaller volcano, or the rocks would pile up again and make themselves somlid again to re-create the "illusion" at least that the volcano was back to normal. As for the wild-life, yes, I do think that they will return back like before.
