[Cueball is on the left, Ponytail is facing him from the right.]

Cueball: We haven't checked in on the Geology Department for a while. I wonder if they're doing okay.

[Ponytail is walking to the right.]

Ponytail: I'll go see what they're up to.

[Ponytail is now seen having opened a door at the left side of a room, within which White Hat, Megan and another Cueball are looking at a chart on the wall, the other Cueball gesturing towards the chart. Most of the chart is illegible, but near the top it says "90 MPH", and below that there's a diagram of geologic strata, with the label "Bighorn Dolomite", upon which a sharply rectangular and isolated rock 'block' is depicted. The rock block has speed-lines indicating its rapid movement from left to right.]

Cueball: 49 million years ago, Heart Mountain, Wyoming slid sideways 15 miles like a giant stone hovercraft.

[Ponytail walks back to the Cueball in the first panel's scene.]

Ponytail: ... They're not okay.

Voice from off the right side of the panel: Hey, you come up with a better explanation!
