Cueball and Ponytail wonder whether the geology department (presumably at a university) is doing okay. Ponytail goes to check in on the geologists, and finds them discussing a theory which sounds ridiculous to her. Someone presumably on the faculty of the geology department proposes that a feature called Heart Mountain slid sideways like a hovercraft, in an attempt to explain some aspect of the geology. Based on hearing this hypothesis, Ponytail concludes that the geology department is not okay.
The actual geology of Heart Mountain, in Wyoming, is very much explained as the comic suggests. The main anomaly is that the rock at the top of the mountain is far older than that of its base. There are other processes that can result in such inverted stratigraphy, but in this case the evidence does indeed seem to suggest that a (more than) mountain-sized amount of rock was rapidly forced to slide a great distance through the action of various volcanic processes on and above a near-horizontal {[w|Fault (geology)|geological fault}}, after which significant erosion has left 'just' the mountain (and some other traces) in its new anomolous position. (As an added bonus, the first maps of the mountain also had it placed in the wrong position, but this was purely human error and totally unconnected to the prehistoric rearrangement of material.)

At some point a giant sheet of limestone... detached and slid southeast towards Bighorn Basin.

Typical, you make a properly researched link to Wikipedia and then, less than two hours later, someone makes it so that someone else has to 'fix' the link and makes me look stupid. (More stupid than I already made myself look, given I might have written other bits of it differently if I'd waited until the morning.) 2.98.65.8 19:15, 1 November 2025 (UTC)
Hi ! First Time commenter here. I wanted to note that the tone of the explanation feels weird to me (it is not specific to this comic, but to most latest explanation). It is very descriptive, dumbing down things that are obvious (panel 1, 2 and 3). I have the feeling the explanation would be better as something like "this is a joke about heart mountain [wikipedia link] <sumary of wikipedia link explaining how the exisiting theories a out heart mountain may look absurd>. Non need to paraphrase each element of the comic, but bette explain the ones that someone may not understand. Am I the only one? Is this remark misplaced? 176.133.138.237 21:57, 1 November 2025 (UTC)Sayanel
- Not out of place. It's a collaborative edit, so different approaches get stacked on each other, with different ideas of what need explaining.
- I personally prefer not to describe things 'as they happen' but, if I'm coming to something already with that format, I'll place the necessarily narrative expansion of details onto that basis. (In this case, though, there was mostly an appending done, not disturbing the original any more than I saw fit.)
- Complete rewrites do get done though. Maybe you want to give that a go. Knowing that dewrites and re-rewrites might well follow, as well as the revamp merely being refined by others. 2.98.65.8 23:21, 1 November 2025 (UTC)

Made some edits to hopefully work better. I still feel the scientific explanation is a bit threadbare, and should be written with more detail of how the conclusion was reached, but I haven't read enough to confidently rewrite that.... 216.221.83.168 16:54, 4 November 2025 (UTC)
"Recent work has focused on release of gas (CO2) along the detachment surface that allowed it to move like a hovercraft." from https://www.geowyo.com/heart-mountain.html 2600:6C54:4E00:99C:67B7:D578:30ED:2471 00:41, 5 November 2025 (UTC)
The explanation above currently says the landslide was 50-75 million years ago. However, the comic agrees with Wikipedia (and references therein) that the landslide was 48-50 million years ago, after a "period of mountain-building" 50-75 million years ago.2601:600:837F:B130:417B:6C65:C169:8DB9 19:26, 5 November 2025 (UTC)
Aside from incorporating further details and suggestions from previous comments, I have also taken the liberty to make major edits to remove what I felt was unnecessary detail or speculation. Reverting my most recent edit will restore what I have removed while keeping the details and corrections. 216.221.83.168 18:56, 6 November 2025 (UTC)
Looking good. But 15 miles traveled at 90mph would take less than half an hour. More like 10 minutes. -- OrwellFan (talk) 03:03, 15 November 2025 (UTC) (please sign your comments with ~~~~)
- With a flying start (and finish) and all at 90mph, it would indeed be 10 minutes. But there'll be a start up and coming to rest. And if it's fragmented into a 'rubble pile' (albeit with mountain-sized lumps) it probably spreads out, the tailings hardly moving and slowing down early, the wavefront of the mass going much further and faster than the 'just moved by 15 miles' Heart Mountain bit.
- So parts travelled 15 miles and parts went at 90m0h and either parts or (maybe) all but a bit of settling happened within just a half hour. (If anybody gets to send back some go-pro cameras through time, there could be some marvellous shots, at least until obscured by the secondary effects.) 82.132.238.20 15:32, 15 November 2025 (UTC)
