Benecke traveled from Kansas City to Denver in the early 1870s, creating a rich legacy of views of the Great Plains at a very early date. In this book, Benecke's landscape photographs are paired with new photographs of the same views. Comparing the old and new photographs, the reader can appreciate how the region has changed in terms of its landscape, vegetation, and human and natural systems over the 150 year time span.Copyright 2024 A.
