“Normal river deposition simply doesn’t fit that bill.”
I agree. But where your conclusion rules out the possibility of catastrophic flooding in a post-glacial period I don’t imagine you’ll care to discuss that idea with me.
That scenario actually fits the evidence better than the premise of a global flood. The ice dam failure would be a localized event, tending to concentrate the sediment deposit in one place. Global flooding would tend to recede in every direction, leaving sediment deposited all across the shoreline.
“But where your conclusion rules out the possibility of catastrophic flooding in a post-glacial period I don’t imagine you’ll care to discuss that idea with me.”
I’d be happy to discuss it. The thesis of this article is in fact that the obvious cause for the deposition is catastrophic flooding, only they don’t believe the source is from glaciers. I think we can both agree that catastrophic flooding seems the likely source.
You suggest the source of that flooding is from glaciers, but how can you determine that, versus flooding from another source? Is there some signature of glacial flooding in the deposit? Or do you only suggest it because it’s the only suggestion that fits the existing narrative?
