Summary:

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.
