If you think Nebraska geology would be boring, think again. the state hosts boiling riverbeds, puzzling fossil beds, and sandstone toadstools, not to mention a dormant sea of sand that once moved fast enough to dam rivers--and these Sand Hills could be on the march again as the global climate warms. But that's nothing new. Changing climate influenced much of Nebraska's geology, from the waxing and waning of continental glaciers to the extinction of some of Nebraska's former inhabitants--one-celled organisms that swam the Paleozoic seas and unusual mammals that evolved on Tertiary grasslands.

Roadside Geology of Nebraska introduces you to the state's rich past and its potentially sandy future. Detailed maps, photographs, shaded-relief images, and road guides describe and interpret the rocks, sediments, rivers, and landforms visible from the state's highways. Thirteen sidebars--scattered throughout the book--delve further into the geologic history of specific sites such as Agate Fossil Beds National Monument, Scotts Bluff National Monument, Ashfall State Historic Park, Toadstool Park, Hudson-Mend Bone Bed, and Indian Cave State Park.
