The Grand Canyon in Arizona is a prime spot for geologists to research the layers of Earth's history. But if you're a Creationist, you might have a harder time getting permission to research there because your theroies don't conform to the mainstream thinking about how the world was formed, including ideas about a historical worldwide flood from the story of Noah's Ark.   Henry Smith chats with geologist Dr. Andrew Snelling from Answers in Genesis about his research in the Grand Canyon, and also his experience of worldview descrimination while attempting to gain permission to retrieve rock samples for geological study.    The Fight for 53 Rocks News about upcoming documentary - The Mountains After the Flood   Music in this episode is from The Grand Canyon Suite, composed by Ferde Grofé
