The History of the Paleozoic Strata The Subsidence The Potsdam Sandstone (and Conglomerate) The Lower Magnesian Limestone The St. Peters Sandstone Younger Beds Climatic Conditions Time involved The Uplift CHAPTER III. GENERAL OUTLINE OF RAIN AND RIVER EROSION Elements of Erosion Weathering Corrasion Erosion without Valleys The Beginning of a Valley The Course of a Valley Tributary Valleys How a Valley gets a Stream Limits of a Valley A Cycle of Erosion Effects of unequal Hardness Falls and Rapids Narrows Erosion of folded Strata Base-level Plains and Peneplains Transportation and Deposition Topographic Forms resulting from Stream Deposition Rejuvenation of Streams Underground Water CHAPTER IV. EROSION AND THE DEVELOPMENT OF STRIKING SCENIC FEATURES Establishment of Drainage Striking scenic Features The Baraboo Bluffs The Narrows in the Quartzite Glens Natural Bridge The Dalles of the Wisconsin The Mounds and Castle Rocks CHAPTER V. THE GLACIAL PERIOD. The Drift Snow Fields and ice Sheets The North American ice Sheets The Work of glacier Ice Erosive Work of Ice. Effect on Topography Deposition by the Ice. Effect on Topography Direction of ice Movement Effect of Topography on Movement Glacial Deposits The ground Moraine Constitution Topography Terminal Moraines Topography of terminal Moraines The terminal Moraine about Devil's Lake The Moraine on the main Quartzite Range Constitution of the marginal Ridge The Slope of the upper Surface of the Ice at the Margin Stratified Drift Its Origin Glacial Drainage Stages in the History of an Ice Sheet Deposits made by extraglacial Waters during the maximum Extension of the Ice At the Edge of the Ice, on Land Beyond the Edge of the Ice, on Land Deposits at and beyond the Edge of the Ice in standing Water Deposits made by extraglacial Waters during the Retreat of the Ice Deposits made by extraglacial Waters during the Advance of the Ice Deposits made by subglacial Streams Relations of stratified to unstratified Drift Complexity of Relations
