Oregon's 22 Kiloton Explosion; The Hole in the Ground

What is that thing? "A big hole in the ground." Yeah I know, but what do we call it? "The Big Hole In The Ground."... I swear, geology gets more interesting every time I watch one of your videos.

[@deanfirnatine7814]

Hole in the Ground is very close to Crack in the Ground, not joking.

[@NightBazaar]

@@deanfirnatine7814 Crack in the Ground had been used as trash dump site. Just a short distance from Christmas Valley, some friends and I back in the early 1960s noticed a sign pointing to it. When we got there we were surprised see all the garbage in it. We thought it was some kind of joke to have a sign pointing a garbage dump as a scenic site. Obviously since then, most of the trash has been removed, but I think there might still be a few old bicycles in there. It's pretty long for a good hike these days. I'm pretty sure most of the Crack was still clean even back then, but we decided to move on and visit Hole in the Ground.

[@AmateurHistorian999]

So maybe Boring, Oregon is actually named after a big bore hole.

[@sjsomething4936]

Whoever named it was incredibly imaginative! 😂😂😂

[@NonEuclideanTacoCannon]

@@NightBazaar I spent a summer in Christmas Valley in the 90s working on irrigation with my cousin. I went and found Crack-in-the-Ground while I was there. I can only imagine the difficulty of removing trash, much of the bottom looks inaccessible. I wanted to climb down and explore, but my cousin reminded me that the helicopter ride to the nearest medical facility is quite expensive.

[@MakerGrigio]

Thank you! Your addition of fort rock to the hole in the ground was perfect. I've been there, it is a bit hard to get to but it is quite the thing to see, the elevated rim is surprising. the Newberry crater is one of my favorite places to camp. I know your coverage of volcanos drives most of the views and subs on your channel, but I really appreciate coverage of these smaller formations.

[@ArtByKarenEHaley]

When you uploaded your older video of this place, I put it on my list of places to visit. There are some rockhounding areas on the route to Hole in the Ground from the Willamette valley. One of my family's planned upcoming road trips will take us near there, since my kids and I are mild rockhounders. and I look forward to seeing it. Last year my husband and I camped near MT. Jefferson and I am going to see if you've made any videos about the mountain. Central and Eastern Oregon is an incredible place.

Your concise explanation of the eruption process really paints a picture in one's mind . . . almost like being there, seeing it. Way cool ..

That Juan De Fuca plate is a real problem, someone should do something about it. lol

[@soyoucametosee7860]

LOL 😂

[@cacogenicist]

The North American plate hears you and is working on it. 😊 ... Juan de Fuca plate will be gone soon (for geological time values of "soon"), when the spreading ridge subducts.

[@Dragrath1]

From Nick Zenter's crazy Eocene A to Z series and some of the related papers I'm pretty sure that explanation is wrong as slab rollback requires the existence of a subducted slab but seismic tomography shows that instead the slab suddenly and abruptly terminates here at the high lava plains with no evidence for any slab continuation to the east. Instead there is a abnormally warm buoyant mantle associated with a linear translationally offset solid mantle low sheer velocity anomaly continuous with the Snake river Plain Yellowstone the Rio Grande rift the Gouda ridge the Juan de Fuca ridge and the East Pacific Rise. In essence this is the site where the East Pacific Rise a deep rooted fast spreading abnormally warm Mid Ocean Ridge cuts beneath North America.

[@johnnash5118]

@@Dragrath1I also connect the EPR divergent activity under the SW NA Cordillera with the B&R extension and the California Trinity conveying NW into Oregon, which is also the source the NW rotation.

Thanks for another great video! I live in Oregon and have been to Fort Rock. Always interesting to see how things came to be. Our local PBS station OPB has a show titled Oregon Field Guide and a recent episode was about a recent scientific expedition to the Axial Seamount. I think you might be able to find it online or even on KZbin. Now I am going to watch your video on it from last year. Somehow I missed it. So cool that the 2015 eruption was actually predicted and the only volcanic eruption to be correctly predicted!! Thank you for such great content.

Nice to get the history of the area, I had always wondered about the features there. I live in the willamette valley, but have done work around the hilariously named "Christmas Valley" area a few times. Oregon just has an amazing variety of features when it comes to geology and biomes. That said, it takes a special kind to get excited about "hole in the ground" oregon. If that's your thing though, I definitely recommend "crack in the ground" as well. Note that Christmas valley has a hotel and 2 places to eat last I checked a few years ago. Those may or may not still be around...

Love the randomness of this showing up on my home screen, and I love learning about random stuff like this. I only have one complaint, only one, and I know it might be a pet peeve of mine, but you seem to hold the mic too close to your mouth and I find the resulting effect on the voiceover distracting 😂 please consider pulling the mic away a bit so it doesn't have that almost ASMR quality to it. Additionally, I'd recommend opening your mouth a bit more when you record these voiceovers in order to give your voice a bit more brightness, and as an added benefit, this can also help compensate for any volume changes from pulling the mic away

[@susiesue3141]

Very interesting! Thanks for sharing. 😊

[@wellscampbell9858]

Question: would there be differences in the remnants of these explosions if they occurred underneath the water as opposed to on land near the lake? Thanks and I love your videos, concise and packed with info.

[@anatomicallymodernhuman5175]

Good explanation of the mechanism. The dates -- maybe. It could have been formed durimg the YDC after the Cordilleran and Laurentude ice sheets melted abruptly.

[@briankepner7569]

The fort Rock outcropping is the location of a cave that they discover 30,000-year-old Indian sandals in and other copper lights indicates that they are One of the oldest proofs of human occupation in the Pacific Northwest. Indicates that there must have been multiple human crossings of land bridges during or just at the peak of glaciation. Both fort Rock and hole in the ground are great places to go visit You can actually camp at hole in the ground. But is also probably not discussed yet in this video is that there's tons of lava tubes in the area that you can freely enter and explore

Pretty good chance that if they occured 20,000 years ago that people were in the area. May have even had people fishing in the lake. In similar lakes in Nevada there are records of villages and fishing communities along the shorelines of these lakes. They probably did not enjoy the big bangs.....

There's a tuff ring On Oahu. The most famous geologic figure in Hawaii.... Diamond head. Or Mt Leahi.

[@StuffandThings_]

What's up with the vaguely circular feature just to the west of Fort Rock? Is it an impact crater? Coincidence of erosion? Volcanic caldera? It seems to have a handful of volcanic features within it and is suspiciously located between Yamsay mountain and Newberry, so it seems like it could possibly be an old eroded caldera. Or, considering the volcanic history of the region and the very large size of this feature, perhaps a very _very_ old caldera from the time when caldera volcanism was going crazy in the region.

[@JackOllie4]
