It's hard to keep up. My prepared statement:

The Younger Dryas may have been one of the 'rapid' phenomena reported.

A silent testimonial in the Eastern Washington state Scablands. www.nps.gov/parkhistory: Geological Survey -- The Channeled Scablands of Eastern Washington

The name "Channeled Scablands" was first used in the early 1920's by geologist J Harlen Bretz of the University of Chicago, who made a comprehensive study of the region and proposed the idea that the erosional features were the result of a gigantic flood. Although Bretz' concept sparked a lively controversy, most geologists today agree that the Scablands were carved by a flood of unprecedented proportions that took place 18,000 to 20,000 years ago during the Great Ice Age.

Thus, before the onset of the Great Flood, the geologic setting of the scabland region consisted of a thick, tilted saucer of basalt, in places warped into ridges and completely overlain by a "frosting" of loess. How did the region look? If one were standing atop Steptoe Butte, the view in any direction would be peaceful rolling grassland speckled with roaming herds of antelope, buffalo, and camel with the distant mountains of the Cascades and Rockies forming hazy blue backdrops to the West and East. This tranquil scene was the setting for a catastrophe!
