"Geology of Devils Tower National Monument, Wyoming" by Charles Sherwood Robinson is a detailed exploration of the famous Devils Tower in Wyoming, examining its geological structure and history. The book explains how the Tower, made mostly of a unique igneous rock, and the surrounding sedimentary formations, which are from the Triassic and Jurassic times, came to be. It talks about different ideas about how the Tower was formed, like whether it was once part of a volcano or if it was created by molten rock pushing up from below. It also discusses erosion and other forces that sculpted the landscape, using pictures and maps to help readers understand the geology.
