Paperback. Condizione: New. Print on Demand. This book records F. V. Hayden's geological observations and insights from the 1871 and 1872 surveys of the headwaters of the Missouri and Yellowstone Rivers. The author describes the geological sections and provides explanations on the significance of the pictured terrain. The author examines the forces that elevated the Rocky Mountains and how these movements affected the sedimentary strata. Hayden also details evidence of erosion due to geological action as well as due to water and ice, the latter attributed to the glacial period. Further discussed are the volcanic activity and the erosion of the igneous rocks and sedimentary beds. Hayden also analyses the local drift deposits in these areas and their composition. This book provides a fascinating glimpse into the geological history of the Rocky Mountain region, and the author's detailed observations make it a valuable resource for geologists, students of geography, and anyone interested in the interplay of geological processes over time.
