The Scablands 

A correspondent brought THIS VIDEO to my attention and it interested me for two reasons. The first is that it is about the Ice Age Floods of the Scablands in Central Washington which I visited on a WEGA excursion led by Doug Robinson in May 2016. We stayed in Ellensburg which is the home of Central Washington University with which the speaker is affiliated.

The second is that it is a journey back in time. He speaks in front of a blackboard with chalk! It brings me back to the days of my youth.

I haven't watched all of the video yet but the guy seems to know what he is talking about. I'm looking forward to seeing the rest.
