I used to think the Grand Canyon was just a big hole in the ground.
I went on a guided hike there last spring and the guide, Sarah, pointed out the Kaibab Limestone layer at the very top. She said it's 270 million years old and was once a sea floor. That made it click for me that I was looking at a giant stack of ancient worlds, not just a hole. Has anyone else had a rock formation suddenly make sense like that?

Got me thinking about Dylan's joke. If we're getting frequent flyer miles for time travel, what's the exchange rate? A million years for one mile? You'd have enough for a trip to the moon just from that top layer. Makes you wonder who's running that rewards program.

The TSA would confiscate those miles at the security checkpoint.

Did your guide mention how many frequent flyer miles you get for time traveling through rock layers?
