Book Description
The extraordinary beauty of the Finger Lakes region is well known to its residents and to the many tourists who explore it each year. What is not so well known is the region's unique geology. Its distinctive features are the results of a singular combination of structural units and forces that operated thousands of years ago, when successive advances of the Ice Age continental glaciers thrust their fronts against escarpments extending across their path and into pre-glacial valleys. How these escarpments affected the flow of ice and how the glacial invasions remodeled the entire region is the subject of O. D. von Engeln's classic study.Following a brief prologue on the region's pre-glacial history, the author discusses each of the region's characteristic features: what caused it, its nature, its relation to other phenomena of the region and, often, to other distinctive topographic phenomena throughout the world. His book is a valuable and accessible introduction to the region's geologic history and provides insights into geologic methodology--how a region gives evidence of its history, what possible explanations for a phenomenon exist for geologists, and how they choose among them.Natives of the Finger Lakes, newcomers, and tourists alike will finish this book with a greater appreciation of this geologically fascinating area and with renewed curiosity about the formative years of our planet.

Book Description
Abstract: Results of a cooperative survey of the central and eastern basins of Lake Erie in 1928-29 by the U.S. Bureau of Fisheries, New York State Conservation Department, Ontario Department of Game and Fisheries, Health Department of the City of Buffalo, and the Buffalo Society of Natural Sciences are presented in a series of papers. Physicochemical data include seasonal, vertical, and horizontal variations in temperatures, water movements, dissolved oxygen, carbon dioxide, phenolphthalein and methyl-orange alkalinity, pH, chlorides, and turbidity. The species composition, seasonal abundance, and distribution of micro- and macroplankton are discussed in detail. Special consideration is given to the influence of polluted river waters which flow into the lake. It is concluded that the lake is remarkably free from chemical and sewage pollution. Evidence of pollution farther than 1 mile from possible sources was detected at only 2 stations. The nutrient level of Lake Erie is high and the lake should support large fish populations.

Book Description
Lakes of New York State, Volume I: Ecology of the Finger Lakes describes the state of Finger Lakes, which is a group of eleven elongated bodies of water of glacial origin in the west-central portion of New York, and its respective watershed. This book assesses the structure of the Finger Lakes' plant and animal communities and how these communities interact with the abiotic components of the environment. The condition of the lakes from the standpoint of fish population dynamics are also analyzed, including an examination of the various physical, chemical, and biological aspects of the lakes' ecosystem. This text ranks the Finger Lakes into a unilateral trophic list by tabulating their trophic information according to three commonly used indicator measurements— average summer Secchi disc depth, average summer chlorophyll a concentration, and average winter total phosphorus level. This publication is valuable to limnologists and ecologists working on temperate zone freshwater lakes.
