About this item

The Roadside Geology series originated in 1972 with Roadside Geology of the Northern Rockies. Fourteen years later, the Big Sky portion of that book was updated to become Roadside Geology of Montana, a bright-yellow field guide that soon graced bookshelves across the state. Now, nearly 50 years after the first book, Mountain Press is releasing this completely revised full-color second edition that, like so many things in Montana, is big. But consider this: no other place in the world has such amazingly diverse and well-exposed rocks with such dramatic stories. For example, Montana lies at the northern edge of the Yellowstone caldera, the world's largest and most violent volcano. A lot of what the wold knows about dinosaurs and their demise came from fossils discovered in Montana's badlands.
