An interesting fact is that the photographer who documented the eruption literally diced with death taking his photos. He photographed a pyroclastic flow that split into two lobes, that reached as far as the cabin he was stationed at. Luckily for him, the cabin was situated in the gap between the lobes, and so was undamaged... and we've got some spectacular photos to marvel at!
Yeah you gotta see the Loomis museum. And "Hot Rock." The boulder that was ejected and flew miles away... And took months to cool down fully. Thank God the brave firefighter heroes save the BF Loomis museum from the power line disaster called the Dixie Fire of 2021. Many historic places nearby did not make it, however. Screw you PG&E. The entire area is a wasteland now, with more devastation and damage than even the volcano could do.
@@KathrynsWorldWildfireTracking Yeah, I lived north of Chico 1988-1992, and I am the one who saw the start of and called in the Campbell fire of 1990. It was a hot August day and the wind was blowing pretty hard. Untrimmed pine trees were swinging back and forth on a foothill ridge in view of my place, so I got my binoculars. Just as I got a closer look, one branch hit a PG & E high tension tower and caught fire. I went and called 911 and the operator said that they'd get to it. I asked them to send a water dropping aircraft (rugged area; hard to get to) but they said that a fire down in the Marysville/Yuba City area was taking priority. I tried to argue that one diverted aircraft might knock this thing out. Nope the 911 operator hung up on me. When they finally got around to it, the fire was way beyond control. It burned for three weeks if I recall, and only luck kept it out of the majority of the town of Cohasset. The Campbell Complex Fire (Tehama County) consumed 125,892-acres, and destroyed 27 structures.
Lassen is my favorite national park. The first time I went there was 1956, when I was 6 years old. My dad, believing an incorrect map, got off on a logging road in Northern California, which broke the tongue of the box trailer carrying our camping gear. Crowding all our stuff in the car, he looked around somewhere closer than Crater Lake to be our vacation target, and saw Lassen. A fascinating place, it got me interested in volcanoes. I've been back several times since, with my parents, by myself, and with my wife. You missed mention of the lahar (they didn't call it a lahar in those days, just a mudflow) that preceded the hot blast (again, their term) by a few days, and followed the same route. The winter of 1914-15 dropped an inordinate amount of snow on the mountain which was still there in May, and which a dacite flow melted. The lahar carried down huge boulders of dacite, the best known being Hot Rock, which was so named because, when seen several days after the eruption, was still very hot. The Devastated Area is now barely noticeable as trees have grown in and are fairly big, but in 1956, just under 40 years after the event, it still stood out.
Lassen is a most wonderful park. Remote, with only primitive camping available, and very few roads through the park. I've experienced snow in July, a sonic boom from a military jet during a 13 mile hike in a secluded corner of the park, a large porcupine crossing the road in front of my car at night on my first trip, an inn/restaurant just outside the park, which nets a few trout from it's pond to cook for your meal. The BEST thing about Lassen: Very few people, and miles of trails, lakes, hills & mountains. And, Bumpass Hell, an area of hot springs and boiling mud pots.
Lassen Peak has a lovely trail to the top. My wife and I have made that hike many times. The whole park is amazing with excellent hikes to a variety of active areas of volcanism.
Yes, but you also have to take into account the eruption frequency of each volcano in California. I don't mean to sound pessimistic, because I'm not a pessimist, but some of California's dormant volcanoes may be overdue for an eruption based their eruption frequency according to the geologic timescale. And if Lassen Peak is one of the most active of California's dormant volcanoes, 100+ years is still too recent to not be concerned about an eruption of a California volcano in the near future. Not to mention that an earthquake along any one of California's many non-volcanic fault lines could trigger an unscheduled, and unexpected, volcanic eruption anywhere, including locations in California where no volcanoes currently exist.
@@GarfieldofBorg Yeah volcanoes activity really isn't cyclical but erratic with prolonged active periods followed by sometimes thousands of years of quiescence. This is probably most pronounced with the extensional volcanism east of the Sierras or down in the Salton trough as these systems seem to go through periods of prolonged unrest with long intervals of quiescence. For example the Salton Buttes appear to have all formed within a roughly 500 year or less interval with their young age accounting for why they are still visible in the subsiding trough with high rates of sedimentation burying old volcanic products. Drill cores indicate that there are older volcanic deposits they are just long buried by the sediments carried into the subsiding basin itself part of the East Pacific Rise. Though I would caution that Lassen is still active even if it isn't erupting dormant is the term for a system which is quiescent but could wake up in the future.
So to add to what I said the other day different volcanic arcs and volcanoes within arcs have different timescales on typical eruptions. The Cascades are a hot subduction zone meaning the crust being subducted is still hot and buoyant and thus has to be dragged down into the mantle by the larger slab its part of in order to subduct at all additionally thanks to the young age there hasn't been a lot of time for water to accumulate either which means you don't have nearly the same level of melting temperature reductions seen at subduction zones with older ocean crust that much more readily subducts and is rich in water accumulated over hundreds of millions of years. This ultimately means the melts need higher temperatures to be produced and thus the threshold for melt generation is a higher bar to pass. This does not apply to the non Cascade volcanoes which are related to extension or rifting that is driven by decompression melting as the crust gets pulled apart.
My father was an exploration geologist, he just retired this year. When we were kids he'd take us rock hounding and fossil hunting all over the western US, explaining rock formations and why we would find what we did where we did. Those were good times; I think this is also the kind of stuff he really loved but reality meant he had to work in oil and natural gas drilling lol
Thanks for sharing. And I bet he was the same - I’m certain he loved what he did in oil and gas - but it was the hard rocks and minerals that really got him into geology. Sounds like he had a good career and hats off to him taking his kids out to rock hound. It’s been a good career for me and my family.
Thank you for presenting Lassen Peak complex; It’s my favorite NP! If one were to draw a line on the map from the hamlet of Belden on Hwy 70 to Mt Lassen, the arc crosses 4 eroded volcanic cores at Belden, Humboldt Pk/Butt Mtn, Mineral, and Mt Tehema (Brokeoff Mtn/Bumpass Hell). It is interesting to note that Butt Creek tracks the dividing line between the Cascade Range to the north and the Sierra Nevada Mountains to the south. Curiously, there are no substantial gold mines north of the creek. Though go one ridge south, and the drainage is aptly named Yellow Creek for a reason. Moving eastward, a significant Spreading Zone begins at Canyondam on Hwy 89, bisecting Lake Almanor, and up trending NNW through Klamath Falls and Crater Lake on US 97 roughly corresponding to the subducting Gorda Plate melt. Heading SE of Canyondam on Hwy 89 we pass through the geologically warm Indian Valley with hot springs at Greenville, Indian Falls, and elsewhere. Weather in the Park is temperamental: I last hiked the peak in August 2011 and there was 8 ft of snow at the trailhead. It’s really a one-stop-shop excitement center with a lots of things to see and do. Enjoy! 🐿

Wow! What a great photo! Never seen that one before. That would have been just a very few years after the 1906 fire (caused by the earthquake). Some people must have thought is was signs of the end of the world.
Mt Lassen is a really cool Mt to visit. Hike to the top, and lots of geo thermal springs/mud pots. As others have posted, it is beautiful and awe inspiring! Thanks GH!!!
I visited Lassen Park in either 1972 or 1973.

This place I have a love hate relationship with. I was on a camping trip here for my birthday and was part of a school trip I believe. Unfortunately, during this trip and a day before my birthday, 9/11 happened.

I just in Lassen in July and it was so cool because the moon was enormous and it was absolutely amazing to see it all lit up at night there. Such a cool area. 🌋🌝
I just ran across a feature on Google Earth I'd like to know more about. In the hump of Mexico to the east of the Big Bend there's a good sized extinct volcano. About 50 miles east of Big Bend National park and 50 miles due south of Dryden, Tx. Also, there's a string of what look like cinder cones and about a 2 mile caldera stretching back towards the Big Bend. I'd appreciate something on them. The Central and Southern Mexico volcanoes are well known but I've never heard about any in Northern Mexico.
Got an question for GeologyHub. Have USGS tried to make 3D model of magma storage zones in Lassen Peak center? They did with several volcanoes like Long Valley Caldera, Yellowstone, Newberry, etc. It would be interesting to see what magma storages looks like under Lassen volcanic center.

Oh, ya, from Northern California in to Southern Canada there are some 35 to 40 peaks or mountains the could blow. And besides Yellowstone there are another 2 or 3 calderas in the Western part if the US that could also blow.
Geologists - please stop calling Mt. Lassen "Lassen Peak." It's incorrect, and we locals have been waiting an awful long time for you to respect the real name. Maybe it once had a peak - but it done blew up. Say that around Chester and you'll just prove yourself a newb, or a tourist. (It's not Rainier Peak, not Adams Peak, not Hood Peak, and not Lassen Peak either.) 😊
So far as official names go, I’m afraid your local usage is incorrect. The GNIS has it as “Lassen Peak” (edits.nationalmap.gov/apps/gaz-domestic/public/search/names, search on Lassen and see for yourself). Also, up in Wash, we have Glacier Peak, so it isn’t unique…
I have read that Mount Lassen is not actually part of the cascades and that it is actually part of the tectonic action that has been pushed eastward, including Mount Konocti and Mount Saint Helena at Clearlake

Sir your the best. Please check out MT. Konocti in a thorow demeanor!!!. Lately we gone Orange and by the looks of 5 rather large new steam vents (no words in the American language can describe!)

PS with the 4.7 ago. And the magma pocket growing in a vast distance that preiviously has been unknown or ignored. It is about that time to take a closer look. Call a few people. Usgs , UC Berkerly a field trip. I would like to be part of.

Will you NOT make a video about the new situation, from last week, with the Thwaites Glacier?!?
Professor-Marty.
What new situation with the Thwaites Glacier - I haven't picked up any references to a new development? Though I haven't been looking for one, and as it happens I haven't been looking through my Google homepage much due to health issues.
As to your request, that's a matter for Tim (GH) of course. But this is a vulcanology and geology channel and those are Tim's professional skills, so I doubt if he will see it as within our remit.
Tim, do you want to comment on this?
@@davidcranstone9044 Hello David,
Geology DOES cover such topics.
I asked "Tim" because my other RUclips Channel sources are also, very strangely, NOT covering this topic!?!
Thanks,
Professor-Marty.
Sir your the best. Please check out MT. Konocti in a thorow demeanor!!!. Lately we gone Orange and by the looks of 5 rather large new steam vents (no words in the American language can describe!) Speak threw out lake county. More than visible when it rains. (PS Major rain event this Friday 1/31/25). With the cracks in my walls, the 30ft 1/2in Crack in the dirt driveway. I would say WERE RED!!!!!!!!%@÷=$
👍👍
I have a request for a video, Mt Lamington in Papua New Guinea
👍🙂♥️
This volcano will probably not erupt anytime this millennium as this volcano erupt so much less frequently than even the mono-inyo craters
Poor Californians I've been praying for all of you seam California been cursed or something something's going on seams it's all against you alli hope the curse will be lifted soon.
media hype, we're fine, but thanks

I noticed that you talk too fast on this episode...
I believe Volcanic activity will increase as the Earth’s temperatures rise..
America volcanoes r dead
🤣
Mt Saint Helens wasn’t… did you forget about that or not yet born and not on your radar?
This is literally THE MOST ignorant comment I've _ever_ seen on _any_ platform ever🙄🤦🤦🤦

@@MarkusMöttus-x7jSadly I must disagree - I have seen far worse on this channel, and all too often.
