"The Flood, as Psalm 104:8 seems to indicate, “the mountains rose,
the valleys sank down”, giving us the very uneven surface of the planet we now inhabit. Even Mount Everest, one of the planet’s tallest peaks, would have been uplifted at the closing stages of the Flood, coming into being at that time as a brand-new feature. So no wonder it has limestone with marine fossilson its summit."
