But the more closely the landscape is examined, the more that simple explanation begins to fall short. And interestingly, that explanation is losing favor among many geologists today. You see, the canyon is not

Nate Loper speaking at Missouri Association for Creation Grand Canyon: A Lot of Water in a Little Time How was the Grand Canyon formed—by a slow process of erosion over millions of years by the Colorado River, or in a short time through a massive flooding event? Discover why many leading creation geologists support the model of the Grand Canyon being formed rapidly by a post-Flood lake spillover and a breached dam through the Kaibab Plateau.
