Through the original writings and photography of renowned geologist Harold Rollin Wanless, this book paints a thorough and engaging picture of the White River Badlands’ landscape, geology, biology, pioneer settlers, and how life was lived 100 years ago in a harsh, challenging, remote setting.

In the summer of 1920, Harold Rollin Wanless, fresh from an undergraduate geology degree at Princeton, spent the first of three summers in the Badlands of South Dakota camping, hiking, and collecting fossil vertebrate skulls. Harold produced a fascinating and thorough diary...

The forbidding Big Badlands in Western South Dakota contain the richest fossil beds in the world. Even today these rocks continue to yield new specimens brought to light by snowmelt and rain washing away soft rock deposited on a floodplain long ago. The quality and quantity of the fossils are superb: most of the species to be found there are known from hundreds of specimens. The fossils in the White River Group (and similar deposits in the American west) preserve the entire late Eocene through the middle Oligocene, roughly 35-30 million years ago and more than 30 million years after...
