The Channeled Scabland (Classic Reprint)

Excerpt from The Channeled ScablandThe glacial waterways are river channels, largely made over from preexisting river valleys. (see pl. Evidence for a system of capacious preglacial river valleys is widespread and unescapable. Extending far up on the slopes of these valleys are strongly expressed channel features. In many places the glacial water crossed divides of the earlier drainage pattern, cutting canyon channels where no valleys had existed. Large portions of the scabland channel system, if not all of it, were certainly contemporaneous in origin. These relations demand a volume of glacial water surpassing anything ever previously asked for in geologic interpretation. The time element in the flood hypothesis clearly can not extend through more than the briefest part of the erosion cycle now in progress and is appar ently to be reckoned as a very brief part of one Pleistocene stage. The recency of the flood is attested by the freshness of the land forms it left - as fresh high on the channel valley $10pes as in their bottoms.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
