As to your other point, I think you meant that any geologist seeing the erosion on Mount St Helens would assume that it happened over an extended period of time.
I pointed out the example a few hundred miles away where most geologists assumed the Scablands formed over millions of hours.
It was a geologist, J Harlen Bretz, who figured out that it was a rapid process occasioned by the ice dam melting and unleashing Missoula Lake on the area.
I think this reply was exactly to the point of your St Helens post.
Correct me if I'm wrong on this, please?
...assumed the Scablands formed over millions of hours years.
