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

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