Think of all the people who have driven past this formation, not paying attention, not curious, bored. Your great presentation makes us see "the drama" , makes us see with new eyes.
Geology is cool. Growing up backpacking the Grand Canyon, I developed a love for the science early on. A good teacher like you makes it even better. Cant get enough of your videos. I'd love to take your courses if I lived closer.
Nick, this is extremely interesting and so cool. I love the way you present the landscape as geologists see it, a mystery to be solved. Wonderful video! Thank you to you and your crew.
I love that pink rock! Geology is a neat science in which we use processes and events from today to puzzle out what must have happened long ago. And in this case, it’s multiple lahars from a volcano 10 million years ago which presumably has long since eroded away. And the location of Washington state active volcanoes migrate over time because the North American plate is slowly moving across a hot spot in the mantle?
Great video Nick, thank you. The stretch of highway 10 between Cle elum and Ellensburg is fascinating, from the deposits just east of Taylor bridge that look like conglomerate, to the basalt that the Yakima river is cutting through, and the Lahars down at Thorp.
It's so awesome to see another rock hound running around in older RAV4 !! Loving the content you put on RU-vid Nick ❤️ Been following for a while now, learning so much from ya ...
One of the BEST teacher on earth!!! Only if I Had This kind of teacher,I could have been geologist. Love ALL of your videos,thank you for this lesson.👏👏👏👏👏👏👏👏👍👍👍👍🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🍺🍺🍺🍺🍺🍺🍺🍺🍻🍺🥰🍻🍻🍻🍻🍻🍻🍻🍻
RIDING WITH MY FAMILY ... IN THE LATE '40S ... OVER TO VIST GRANDPA AND GRANDMA IN BUENA ... THAT FLUME BEHIND YOU ... AT 1:33 ...WAS "GRANDPA'S DITCH" ...
Thank you Nick! I now have a summer motorcycle mission; to experience those places, and spectacular formations in person. In geologic terminology is there a specific name for solidified lahar deposits?
Nick do you think this is only one Lahar or multiple Lahars? I'm thinking it's multiple because it appears there are layers that look very different from each other
Hello Nick, you should see an area called the Squamish River Valley. This area is one of the most beautiful areas in BC, that is accessible by car, and is close to you. Perhaps, you should know about one of the most beautiful mountains in the world. It is called Pyroclastic. It is close to Squamish and something you probably have never seen before. Very rare shape. People always think about Whistler, that is a Tourist trap. I would love to give you a Tour and show such beauty that you will start crying tears of Joy. In your life, you must drive to the end of the Squamish Valley Road and go to the Elaho Valley. Trust me! The most beautiful valley with it tributary canyons in Canada. So easy to get to and close to you too. If you need info, just ask. I have done a lot of backroading in this area.
Great stuff! Thank you. My son has lived in Bellingham for years - and he has talked about how incredible Squamish is. I will be heading your way soon.
>^..^< Lots of time, lots of unique occurances in this time that was not burried by organic refuge mixed with sand, clay ect kept exposed by lots O wind and water.............. Keep up the interesting good work Mr. Z.........
Dude! I'm a retired septuagenarian and very much enjoy your videos. If you were permitted, we would buy you a beer! Well done! You should consider teaching! LOL
Almost looks like conglomerates where the rocks are except your pebbles are easy to retrieve and the conglomerates in the Upper Peninsula of Michigan are really hard.
Sir, thank you once again, for your hard work in producing these types of videos. Unfortunately, the music in the background, passing traffic and wind noise, just about drowned your reporting.
Excellent Video !!! The internet is a great aspect for learning about the world. Would you label this as a pyroclastic flow? Why or why not? Thanks! - Southern California (I’ve been the Seattle and Olympic National Forest. It’s gorgeous there!!!)
Pyroclastic flows and lahars have fundamentally different mechanisms of formation. The name pyroclastic is suggestive. Pyro, as in fire. In other words a pyroclastic flow is hot when it occurs. Clastic comes from clast which means something composed of pieces of rock broken off from elsewhere. In the case of a pyroclastic flow the breakage is caused by volcanic explosions. So a pyroclastic flow is a flow of hot pieces of rock broken up by a volcanic explosion. Lahar on the other hand is an Indonesian word which essentially means a mud or debris flow. Lahars are generally not hot when they occur. They can still be warm, but if you point a thermal camera at a lahar you will not find temperatures of hundreds of Celcius, whereas you certainly would in a pyroclastic flow. Lahars tend to have a strong component of water in them, whereas a pyroclastic flow would flash any water to steam. Lahars can certainly contain pyroclastic materials, but those pyroclastic materials may be juvenile (newly created) or equally they may be remobilised (washed from an existing deposit). A pyroclastic flow always occurs during an explosive event. The smallest such events are what is called phreatic in nature. In other words water falls on the mountain, percolates down, interacts with the magmatic system, gets heated into steam and explodes. No new (juvenile) magma is involved in the process. These eruptions can still be deadly however. A good example of a recent, extremely deadly phreatic explosion is Mount Ontake in Japan in 2014. 63 people were killed. Go up the scale and eruptions can be phreato-magmatic. In other words it's a mixture of juvenile magma and water flashing to steam. Most pyroclastic flows are purely magmatic in origin however. They occur from all medium and large explosive volcanic eruptions. The lateral blast from Mount St Helens in 1980 was a pyroclastic flow. The stock pictures of a tropical volcanic eruption from Montserrat that you often see are pyroclastic flows. They also occurred at Krakatoa in 1883, Tambora in 1815 and during all VEI 8 super-eruptions. Even Kilauea on Hawaii can produce pyroclastic flows on occasion as it did most recently during the 1790 eruption. In these events they generally happen for one of two reasons. Either an eruption column from a big explosion can no longer support its own weight, collapses and flows down the side(s) of the mountain or a structure called a lava dome forms from viscous lava, gets over-steep and collapses. As I've stated further up the paragraph there is a third, much rarer, mechanism for pyroclastic flows in large eruptions which is a lateral blast. When a pyroclastic flow comes to rest it normally forms a comparatively loose deposit. However in certain unusual cases what is called a pyroclastic base surge occurs and when that comes to rest it is so hot that a process called welding occurs. In other words the components of the pyroclastic flow are effectively glued together, forming a much harder and more consolidated deposit known as a welded tuff. These are extremely rare and normally occur when a lava type called rhyolite is involved in the eruption. The most recent good example of a welded tuff was deposited during the Novarupta eruption in 1912. It's known as the Valley of Ten Thousand Smokes. Lahars on the other hand can occur without any volcanic involvement at all (other than the initial eruption which created the deposits of course). They can occur decades or even centuries after the eruption which created the deposit. They need a source of water to occur. That water can come from particularly heavy rainfall or from a melted glacier during an eruption. Essentially the water mixes with the volcanic deposit and creates a slurry which flows down the mountain. Other than ash fall lahars are the volcanic hazard which is most directly deadly at the greatest distance from the mountain. They can travel tens of miles from their origin point. They can also kill a great many people. One of the things that made the 1991 Pinatubo eruption worse than it otherwise would have been was the fact that a VEI 6 explosive eruption coincided with a typhoon making landfall! So there were many more lahars from that eruption at the time of the eruption than otherwise would have been the case. The deadliest volcanic event of the last century was due to a lahar. Nevado del Ruiz erupted in 1985, melted its summit glaciers, created a lahar and said lahar buried the town of Armero. Over 20,000 people were killed. The only volcanic event during the 20th century that was more deadly was in 1902 when pyroclastic flows from the volcano Mount Pélee on Martinique destroyed the island's capital city and killed nearly 30,000 people. In Washington state itself it's lahars that pose the biggest threat to life. Many of Mount St Helen's casualties in 1980 were caused by lahars, but the biggest threat of that type is posed by Mount Rainier. Its lahar deposits quite literally reach the outskirts of the Seattle metropolitan area and Puget Sound. Those particular deposits come from a fairly famous eruptive event some 5,600 years ago called the Osceola eruption.
Nick, as a local I take exception to the point you make about locals believing that this is sandstone. I knew this was lahar when you were still in 1st grade.
This is how you find things , watch for the energy , what's the horse power , necessary to make this happen. What is it, really , and how did it arrive? ( The gold is at the bottom)
Let's see... a couple of hundred years of observations, everyone from builders to oil companies using science to accurately predict the behavior and composition of the crust. On the other hand, we have someone posting on the internet that there's a global conspiracy out to get them. Now let's apply Occams' Razor: What's more likely, a global conspiracy involving corporations, universities, science journals, scientists, popular science magazines, investigative journalists. Or just a handful of people with well known and well documented emotional or psychological defects that make them crave attention and drive them to post idiocy on the internet specifically because it will get a response from the rational adults in the room. Global conspiracy involving every nation on Earth? Or some random idiot on the internet babbling. William of Ockham weighed in on which he thinks is more likely. How about you, got any thoughts on which of those scenarios is more likely?
He is showing you how geologists figure out what is happening with our earth and how it got there. If you don’t want to learn your self so be it, but don’t try and mess with other people who do. Rabid neo conservative, let me guess, flat earthers. Just because YOU don’t want to learn about the planet we live on...... go back to watching the UFO channels.
Funny, seems it is a petrified snake. Seems to be a lot of them also. I do not think geology theory of rocks is more than jibberish. You can see the petrified snake everywhere. It seems to be used as construction material. Try using your eyes and not what you have been taught to think for a change?
Geologists only think and talk about periods of millions of years. They have different methods for determining the age of rock layers. However, there is one small problem. Ancient books tell us that a cycle of natural disasters threatens the earth and all living things. The cause of this cycle of disasters is a ninth planet in our solar system orbiting the sun in an eccentric orbit. Features of the natural disaster include a massive tidal wave, higher than the highest mountain, flooding, storms, rain, volcanic eruptions, earthquakes, and a fiery asteroid bombardment. That planet is surrounded by a gigantic twisting cloud of dust and meteorites. That cloud obscures the atmosphere, pollutes the water and covers the whole planet Earth with that dust. At the end of the crossing of this planet 9, the earth is covered with a horizontal layer of wet mud, a mixture of sand, clay, lime, fossils of sea and land animals, shells and the deposit of that dust cloud and asteroids. So in every layer on our planet we will find material of the same antiquity, perhaps many millions of years old: the deposit of extraterrestrial clay and meteorites. Even the youngest, topmost earth layer, which is less than 6,000 years old, also includes the same very old deposit. If you don't know about this cycle, you have no idea how our history has evolved. To learn much more about planet 9, the recurring flood cycle and its timeline, the re-creation of civilizations and ancient high technology, read the e-book: "Planet 9 = Nibiru". It can be read on any computer, tablet or smartphone. Search: invisible nibiru 9
