Considering the vast ages of comparable piles of rocks shouldn't be that captivating, but then of course tumblr has its way of making seemingly boring details extremely interesting. For instance here's a tumblr thread about various sciences judged on their lickability.

    Font - archosaur-automaton The Rockies are new, young and virile and fresh from the Laramide orogeny, tall and lanky teenagers on the geological scale. the Appalachian mountains are old, formed hundreds of millions of years ago before dinosaurs walked the Earth. They are ancients, elders, witnesses to half a billion years of life coming and going.

    Sky - To be tall is not a virtue. To be small is not a sin. The Appalachians are eroding under the weight of time, slowly shrinking and returning to the Earth from which they sprang. Appreciate them while they are still here.

    Font - beabaseball I do want to say real quick again about the age of the Appalachians.. They said "before dinosaurs," but we have a cave here that began forming between 450 million to 550 million years ago.

    Font - There are no bones in that cave. No fossils. No nothing. That's because this cave began forming before bones existed on land, and had only just started to exist in the ocean. Shellfish hadn't evolved yet. Limestone, which forms many caves, was just starting to become a more prevalent rock.
