Cataclysms on the Columbia front cover
Cataclysms on the Columbia tells two stories. One follows geological research that challenged the scientific paradigm of the early 20th century, and the other chronicles the results of that research: the discovery of powerful prehistoric floods that shaped the Pacific Northwest. The last Ice Age left scabland buttes, dry falls, and old river channels in its wake, but it took the detective work of geologist J. Harlan Bretz to prove it to the world. With a lifetime of research and an unshakeable belief, Bretz made history and changed geology forever.
