The Ice-Age History of National Parks in the Rocky Mountains
Editorial Reviews
Midwest Book Review
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 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. The Ice-Age History Of National Parks In The Rock Mountains relates ass well the kinds of evidence and methods scientists use to recover past environments. Covering geology, climate, ancient plan and animal life, and human presence, Elias introduces paleoecology (the interactions among plants, animals, and the prehistoric ecosystem) to non-specialist general readers. A perfect companion to any hiker, tourist andarmchair traveler interested in the western parks of the Rocky Mountains.
