A canyon similar to and one fortieth the size of the Grand Canyon was formed [by the 1980 eruption of Mt. St. Helens].Sure, if by similar you mean loose volcanic ash, mud, and debris is as hard as 3600 feet of sandstone, limestone, and schist aggregated over the course of millions of years. Ms. Weigand doesn't reveal the source of her dimensional calculations, but it's oft-repeated creationist nonsense and the comparisons between the Grand Canyon and the Toutle River are ludicrous. The author's husband, David Weigand, was recently elected to the West Bend public school board.
Is this the manner of "science" they want to teach up there?
For entertainment's sake, let's hope so.
