Every vista in Montana tells a geologic story, and in Montana Rocks! author Rob Thomas selects sixty of the very best geologic sites to reveal how the Big Sky state’s landscapes were built, reshaped, and transformed over time. 

Each carefully chosen stop is  a geologic time capsule, brought to life with beautiful photographs and clear maps and illustrations that shed light on crucial details. The sites are organized chronologically, inviting armchair readers and travelers alike to journey through the state’s geologic history from some of the world’s oldest rocks on the Beartooth Plateau to recent rockfalls in the state’s biggest city, Billings. 

With this book in hand, visit a nesting ground of dinosaurs, an earthquake-triggered landslide, volcanic rocks from a fiery eruption of the Yellowstone supervolcano, and thrust faults that carried entire mountains over younger rocks, bringing Montana’s long and complex geologic history into focus.
