Why aren't all lavas (below some point) pillow lavas, as they should have been extruded under water? In fact, features of normal land life are visible up and down the geologic column from the time life colonized the land. Not just land life forms, but hardened tracks, raindrop imprints, glacial scarring, sandstorm residue, crystallized salt, fossilized dung, etc. These things do not form or harden under water.
Why so many layers with such obviously different histories? You can't account for all the kind of things below with a flood story.
While the specific example is fictional (to illustrate relative dating principles), it's not unrepresentative.
