It does push up and crumble again. What was visible in person (that doesn't show up in the pics) was a large 'tower' that was new last time since my earlier visit. This tower was evidently many stories tall and was destined to fall over. Again, it's hard to grasp the scale of it, even when you are looking at it.
Sorry, HairOfTheDog, from the post with the pictures I thought you didn't understand what the mountain was doing. You probably already have all of those links in my previous post.
I can only imagine.
