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.
Standing before any of southern Utah?s enigmatic landforms, it?s clear there?s a story here. What carved the goblins in Goblin Valley, the domes at Capitol Reef, the towering sandstone walls of Zion Canyon, and Bryce?s hoodoo fairyland, not to mention all those arches and natural bridges? Geology Underfoot in Southern Utah explores the stories behind 33 handpicked sites, some world-famous, others off the beaten path. Marvel at tales of ancient eruptions, deserts, seas, and swamps; the movements of massive rock units over eons; and the rock?s interactions with the life above it, including humankind. Along the way, visit dinosaur trackways, old mines, rock glaciers, oysters in the desert, and more.
