VOLUME ONE: GEOLOGIC WONDERS OF THE NORTHERN PLAINS. The geology of the Great Plains is a product of long epochs of sedimentary buildup followed by equally long epochs of erosion. The result today is a dramatic landscape of bluffs, pinnacles and badlands that contain the rich story, of ancient sea creatures, dinosaurs and long extinct, giant land mammals. But it was the rising up of the Black Hills in the vast Great Plains that created incredibly dramatic geological features. This volume contains three chapters: Devils tower national monument, Jewel Cave National Monument, Agate Fossil Beds National Monument.
