Book Description
"During the last ice age, glaciers formed high in the Rocky Mountains and carved out the peaks and valleys visible today. Recreating the landscape and life forms of this era of the last great glaciations (from 10,000 to 125,000 years ago), this guidebook describes a little-known yet pivotal period in the ecological history of four western national parks: Glacier, Yellowstone, Grand Teton, and Rocky Mountain." "Scott A. Elias describes how great sheets of ice spread over and changed the shape of the land - forming the steep-walled valleys and braided rivers of Glacier National Park, the chain of so-called "pater noster" lakes in the lower Rockies, and the end moraines that dammed Jenny, Bradley, Taggart, and Phelps lakes in the Grand Teton park. Drawing on fossil evidence, he also introduces the large animals that thrived 21,000 years ago - dire wolves, short-faced bears, American cheetahs, and mammoths - and that quickly died off at the end of the last glaciation. He recounts the coming of humans to the region, the ascendance of the ecosystems we see today, and the lasting features (plant, animal and topographical) of the ice age." "This guidebook, along with its companion on the ice-age history of Alaskan national parks, relates as well the kinds of evidence and methods scientists use to recover past environments. Covering geology, climate, ancient plant and animal life, and human presence, Elias introduces paleoecology - the interactions among plants, animals, and the prehistoric ecosystem - to hikers, tourists, and armchair travelers."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Book Description
Elias describes how the increased precipitation and cooler temperatures of the Pleistocene affected the desert environment. He also traces the impact of ancient cultures on the landscape, from the earliest inhabitants to the Anasazi.

Book Description
Drawing from his years of biological research within and adjacent to the sixth most visited park in the US, and from files and reports of the park's own biologists, Hess presents a strongly worded, well- documented indictment of gross mismanagement. His analysis diverges from Alston Chase's Playing God in Yellowstone in a number of respects; the case he makes is his own, and he presents a proposal for rescue.

Book Description
Prato and Fagre offer the first systematic, multi-disciplinary assessment of the challenges involved in managing the Crown of the Continent Ecosystem (CCE), an area of the Rocky Mountains that includes northwestern Montana, southwestern Alberta, and southeastern British Columbia. The spectacular landscapes, extensive recreational options, and broad employment opportunities of the CCE have made it one of the fastest growing regions in the United States and Canada, and have lead to a shift in its economic base from extractive resources to service-oriented recreation and tourism industries. In the process, however, the amenities and attributes that draw people to this 'New West' are under threat. Pastoral scenes are disappearing as agricultural lands and other open spaces are converted to residential uses, biodiversity is endangered by the fragmentation of fish and wildlife habitats, and many areas are experiencing a decline in air and water quality. Sustaining Rocky Mountain Landscapes provides a scientific basis for communities to develop policies for managing the growth and economic transformation of the CCE without sacrificing the quality of life and environment for which the land is renowned. The book begins with a natural and economic history of the CCE. It follows with an assessment of current physical and biological conditions in the CCE. The contributors then explore how social, economic, demographic, and environmental forces are transforming ecosystem structure and function. They consider ecosystem change in response to changing patterns of land use, pollution, and drought; the increasing risk of wildfire to wildlife and to human life and property; and the implications of global climate change on the CCE. A final, policy-focused section of the book looks at transboundary issues in ecosystem management and evaluates the potential of community-based and adaptive approaches in ecosystem management.

Book Description
Until recently a geologist was visualized by most people as a queer sort of fellow who went around the countryside breaking rocks with a little hammer. Fortunately, the general public today has a much clearer picture of the geologist and his science, but there are still many among us who mistakenly feel that geology is something too remote for practical application.Geology is the science of the Earth. It includes a history of our planet starting with its origin, and a history of the life that has lived upon it. From it, we can determine the reason for every feature of the landscape and every rock structure underneath the surface, and we can further learn what processes gave rise to them.

Book Description
Focusing on more than 30,000 years of Alaskan prehistory, The Ice-Age History of Alaskan National Parks vividly describes the geology, climate, ancient plant and animal life, and human presence in four of Alaska's national parks and preserves - Denali, Kenai Fjords, Glacier Bay, and Bering Land Bridge. Scott A. Elias uncovers a time when glaciers shaped the landscape, gouging out valleys, carving cirques and peaks, and leaving moraines that blocked rivers and formed lakes. Using fossils as "witnesses" of past environments, he recreates the bogs and steppe tundra where caribou, moose, saber-toothed cats, and mammoths reigned 35,000 years ago. This guidebook presents a unique perspective for the modern traveler. Geared toward the general reader, it is the first in a series that will also survey the prehistory of the Rocky Mountain and Southwest national parks.

Book Description
This book will provide a complete overview of an alpine ecosystem, based on the long-term research conducted at the Niwot Ridge LTER. There is, at present, no general book on alpine ecology. The alpine ecosystem features conditions near the limits of biological existence, and is a useful laboratory for asking more general ecological questions, because it offers large environmental change over relatively short distances. Factors such as macroclimate, microclimate, soil conditions, biota, and various biological factors change on differing scales, allowing insight into the relative contributions of the different factors on ecological outcomes.

Book Description
From Rocky Mountain National Park in Colorado to the Tallgrass Prairie National Preserve in Kansas, this volume provides a snapshot of the most spectacular and important natural places in the Great Plains and Rocky Mountains. America's Natural Places: Rocky Mountains and Great Plains examines over 50 of the most spectacular and important areas of this region, with each entry describing the importance of the area, the flora and fauna that it supports, threats to the survival of the region, and what is being done to protect it. Organized by state within the volume, this work informs readers about the wide variety of natural areas across the Rocky Mountains and Great Plains and identifies places that may be near them that demonstrate the importance of preserving such regions.
