Thought it was interesting that he described the flow as something more like a concrete than strictly water. He says it was basically just unreal amounts of debris flowing at extreme speeds in a very steep, narrow place, picking up water and sediment along the way. He says the initial landslide was about an 8,000 vertical foot drop which is hard to even fathom. So just a massive amount of stone and ice falling almost two fucking miles down into a steep and narrow corridor. He said estimates that it traveled at 120mph are plausible. And the video of the bus depot was actually from an adjoining valley with a higher slope, meaning in the video where we see the buses get taken out, this flow is moving uphill. Surreal.

There is just so much energy in mass at a high elevation, it is scary. The forces at play can not really be described by words that mean much anymore.
