The Creation Museum is a terrifying place for scientists of all stripes. One of their exhibits is the "Flood Geology" exhibit, which purports to explain how a flood of (literally) Biblical proportions circa 6000 years ago explains all the features of the Earth we see today. One panel at that exhibit is titled "Evidences of the Flood in the Grand Canyon":
This is obviously boneheaded in so, so many ways, but anyway - this panel makes the following claim:
Sand grains in the Coconino Sandstone come from the Appalachian Mountains.
Three related questions:
- Is this claim true? (The Creation Museum is not beyond telling outright lies, so I have to ask...)
- If so, how did it get there?
- How do we determine that a particular grain of sand originates in the Appalachians?
