|STILL NOTHING, GUYS|
OK. I read the text on one of the formations.
Still nothing about how they come up with 250 million years old for the Kaibab Limestone.

You clearly didn't attempt to check a single one of the very comprehensive list of references, did you?
If we showed you a recipe book, and there were a recipe on page 116 for an apple pie, and the recipe started by saying "Make a crust according to the pastry recipe on page 53", you would probably say: "I've read the recipe on page 116 and it still doesn't tell me how to make the crust!"
