Glacier National Park: A Culmination of Giants: America's National Parks

Bristol takes readers on a journey through the history of Glacier National Park, beginning over a billion years ago from the formation of the Belt Sea, to the present day climate-changing extinction of the very glaciers that sculpted most of the wonders of its landscapes. He delves into the ways in which this area of Montana seemed to have been preparing itself for the coming of humankind through a series of landmass adjustments like the Lewis Overthrust and the ice ages that came and went.
 
First there were tribes of Native Americans whose deep regard for nature left the landscape intact. They were followed by Euro-American explorers and settlers who may have been awed by the new lands, but began to move wildlife to near extinction. Fortunately for the area that would become Glacier, some began to recognize that laying siege to nature and its bounties would lead to wastelands.
 
Bristol recounts how a renewed conservation ethic fostered by such leaders as Emerson, Thoreau, Olmstead, Muir, and Teddy Roosevelt took hold. Their disciples were Grinnell, Hill, Mather, Albright, and Franklin Roosevelt, and they would not only take up the call but rally for the cause. These giants would create and preserve a park landscape to accommodate visitors and wilderness alike.
