Description: Following in the footsteps of Lewis and Clark, John Hoganson and ì Ed Murphy lead readers on a geologic tour of the Missouri River ì valley in western North Dakota, explaining the geologic wonders ì that Lewis and Clark recorded in their journals-burning coal ì veins, petrified trees, cannonball concretions-as well as more ì modern discoveries such as dinosaur fossils. Color photographs, ì maps, and paintings complement the explanations of the geologic ì features exposed in highway roadcuts and along the riverbanks and ì bluffs.

You'll learn the origin of the Knife River flint that American ì Indians traded across the Great Plains, the source of the ì pumicelike rocks that float on the water, and the history of ì North Dakota's only offshore oil well-in the middle of Lake ì Sakakawea. Geology of the Lewis and Clark Trail in North Dakota ì includes a history of the scientific objectives of the Lewis and ì Clark Expedition, an overview of North Dakota geology, a ì glossary, a bibliography, an index, 150 color photographs and 25 ì color maps.
