Graham and Randall investigate a massive boulder believed to have been carried by a historic flood event in the Pacific Northwest, discussing its distant origins and geological impact. The chapter delves into the controversial theories of massive flooding proposed by geologists like Harlan Bretz, the formation of colossal waterfalls like Dry Falls, and the comparison between ancient catastrophic floods at Grand Coulee versus Niagara Falls.
