This is a unique collaboration between two observers who have, for more than twenty-five years, been examining landscape change in the Canadian Rockies -- national park biologist Cliff White & Canadian Rockies historian Ted Hart. Working with historical photographs, White has retraced the steps of the original photographers & taken new shots in the same locales, a technique known as "repeat photography". Comparing these images side-by-side, the authors show the dramatic changes to the Rockies landscape that have occurred over the years. The sets of photographs generally follow ecological regions moving west from Calgary & the foothills, ascending through the low elevation montane zone of Banff National Park, upwards into the lower & upper subalpine. The authors then follow the historic photographers’ routes for brief forays onto the west slopes of the Rockies in the Columbia River watershed of British Columbia, & east into the Front Ranges along the Red Deer & North Saskatchewan rivers. Moving north, the photographs depict the high windswept alpine zone & glacial ice of the Columbia Icefield, before passing through Jasper National Park & turning eastward to descend to the parkland region at Edmonton, Alberta. Useful captions describe the landscape changes visible in each "then & now" view, & five essays more fully explore the historical, political, & ecological processes at work. Illustrated throughout with striking images, this book is at once a showcase for the beauty of the Rocky Mountain landscape & a valuable source of information about ecological change in this world-famous region.
