The Channeled Scabland of Eastern Washington

In this article, Bretz proposes the formation of the system of buttes and canyons known as the Chaneled Scablands are the result of a massive glacial flood. In Bretz\u27s words, this region contains evidence of vigorous subfluvial action. This article is 32 pages.https://dc.ewu.edu/spc_pubs/1001/thumbnail.jp

Age of the Spokane glaciation

In this article, Bretz describes two glaciers that reached then drained through the northern part of the Columbia basalt plateau. Based on the physical evidence, Bretz attempts to determine when the earlier Spokane glaciation occurred relative to the Wisconsin glaciation. This publication is 7 pages long.https://dc.ewu.edu/spc_pubs/1004/thumbnail.jp

Carlsbad Caverns and Other Caves of the Guadalupe Block, New Mexico

The limestone caves of this region were made under completely saturated conditions long before the present erosion cycle began and probably before the Pliocene Ogallala formation was deposited

Caves of Illinois

LimitedCaves are fragile environments and are protected under the Federal Cave Protection Act of 1988. This document identifies locations of caves in Illinois. Over the years, a number of caves have had irreversible damage from vandals. Visitors also exacerbate the problem of white nose syndrome, which is severely reducing Illinois bat populations. This report should not be made easily available in digital format to individuals who may access caves without knowledge of or respect for the extremely fragile nature of the cave environment
