An amazing lady as well. Please thank Liz for our intrusion into her home and backyard for all of these months. You have a keeper there Professor! Be healthy, be safe. Love you guys!
‘NED On The Fly’ #8 - Ned Searches for all his Lost Hammers! Thanks again for the wonderful vid, showing, explaining Blue, Green Schist in nature. Rock On Nick!
well, no wonder Liz is so buffed! Carrying rocks to the car that big...lol It really should make us all appreciate the work done and being done by geologists and students looking at the difficulty of the hills and mountains to piece together the geologic story. Years and years of data collecting figuring out the puzzle.
@@bagoquarks hahahaha true so true! If we were consulted on the gifts given to Nick I wanted to get him a dry-erase board that has a metal backing and uses magnets. I have one and paper stays put.
When I saw Liz i was like 'holy crap, dang, that girls in shape!!' -- first she walks out and back on the rock out cropping like it's nothing, then later in the video she's carrying that rock like it's nothing!! AWESOME!!
Don't forget to THUMBS UP for Nick! Another terrific geology lesson video! What an amazing story accompanied by spectacular views, beautiful scenery, and blue and green schist rocks! It's mind-boggling to me that you can climb thousands of feet up a mountain and end up standing on an ancient ocean floor... that traveled hundreds, maybe thousands of miles north to get there!
Great episode Nick! What great exposures of the green/blue schist. Thanks for confirming that I’m pronouncing “glaucophane” correctly. Love that rock. We have plenty of it down in SoCal along the coast, but it’s broken up fragments within the San Onofre Breccia; thought to be from submarine landslides coming off of islands that accreted long ago. Looking forward to your next episode already!
*SCHIST VARIETIES:* Per Nick, the blue schist started as 160ma ocean floor basalt (igneous) and got "cooked" at 300 degrees Celsius at high pressure. In contrast, the Wissahickon Schist found here in the Mid-Atlantic states has a significantly different beginning. The Wissahickon Schist formation also started on the ocean floor but as (pre-Atlantic) sediments: (a) sand -> sandstone -> quartz/quartzite, or (b) clay -> shale -> mica;. These sediments are 550ma, were alternating mica and quartz layers, and were "cooked" at 550 degrees Celsius at high pressure (20+ km depth). Additional minerals include feldspar, biotite, and garnet. Wissahickon Schist is dominated by dark and lighter browns and is quite sparkly in good light. Regional note: (clay -> shale ->) slate is popular in East Falls for roofing and paving. It's "cousin" the Wissahickon Schist has been a building and wall block material in Philadephia for decades.

Now I know where the blue rocks that I laid all around my yard come from. Could only find them sold at one place here in Bay Area, Cali. Someone once said that the Ocean terrain, as we know it now, holds the highest mountains in the World. Can only imagine what the topography looked like when this area you are in was young and deep under the Ocean floor. So beautiful! Good photography, sound and Nick's gift of the heart and soul has truly enriched my world this morning! Ahhhhhhhhhhhhh
Highest mountain in the world from base to peak IRRC is Mauna Kea. Measuring from the ocean floor. to its peak ofc. Everest is a wee sma' one in comparison if you measure from the base and not sea level.
U paid good money for rocks ? Lol , far more fun to find ur own ! I lost my White Marbel rocks i found yesterday in Cottonwood creek, near Mabel lake BC, off the bow of my Boat when we hit big waves ! 🙄.oh well , lots more there, ROCK ON NICK! Luv ur shows
Thank you Nick! We have some of this blueschist (I used to call it greenschist, thank you for the correction!) in the Klamath Mountains where I grew up (Mt. Shasta). A beautiful rock and the story of its transportation from Baja to Washington is incredible! Thank you for pointing out the Straight Creek Fault as well! Looking forward to your next installment....
Always wonderful and super informative. It is completing a huge item on my bucket list in a manner I can understand and manage (@77 years old) I cant thank you enough.
Love your live and posts. Earth is an amazing place to be part of. Understanding makes it even more amazing. Human nature is always "asking " for more. A blessing , if you are open minded. A curse if you think you already know! We will NEVER know everything. Not in the big Plan.
40 kilometers is 24 miles - a fair distance "underground" for this former sea bed rock to have been formed before uplift brought it far above sea level. Not a geologist, nor am I likely to be at my age (76), but I'm enjoying the "big picture" views of how the landforms of the western U.S. came about that Professor Zentner presents.
I always enjoy your videos. You have inadvertently justified ex-Californians moving to the NW; we are just following our roots, I mean, rocks. (I live near CDA so I know we are in a different terrane, but I like to see the humor where I can find it.)
I love learning about this beautiful state we live in from you Nick. You are a great teacher and a delight to watch. Thanks for all that you do. Happy Adventures🐾
Prof Nick and Liz, Thank you for sharing your travels in Eastern Wa and to continue to educate us about it's history and how it formed with water, pressure and rocks and how it relates to the histories of North America too. The scenery is beautiful, just down the road from home!
Once again I have learned something, and had a wonderful hike in the mountains, which is vital to my survival in downtown Seattle. I love exhotic terrain! So you have my attention. Thank You, Professor Nick.
I'm not getting to see all these on the fly episodes live but am loving them after the fact. I love this state we live in and your excellent teaching brings its geology to life. I really can't thank you enough.
Here in the Appalachian Piedmont it's almost 100% metamorphic rocks, with areas of intrusive rocks for flavor. I have a bit of mica schist with (tiny) garnets, long black crystals of hornblende, and tiny crystals of quartz sitting on my desk. I picked up from the ground outside my office.
Wonderful! This is exactly the level of technical detail, combined with beautiful scenery, that makes your videos so interesting. It really helps to see the rock up close. Now I think I can identify it when I find it. Thank you.
You had me at the green shoes & blue shorts Nick! Love your "work"! So far from Wesconson, but aren't you so grateful for the free Country that allows this !!! If so, thank a Veteran.
This will be some gneiss schist, so it's definitely worth waiting for! I'll be on the road so will have to check it out tomorrow. Thanks for doing this program Nick.
On Marathon Island in the Florida keys Mark Twain built a spectacular home out of stone blown from the hillsides of North Carolina when they were building the railroad south for national security (wink wink) and chose the location of the highest natural point above sea level on the island which happens to be a huge slab of green schist which is really neat to see. I was only there once 25 years ago on a golf cart tour of the island but it was very memorable and I would really enjoy seeing it again someday. If you have the chance I would recommend it strongly but warn that it is quite expensive to stay there, like $450.00 per night for a basic room expensive.
Southern Oregon has some of this metamorphic. Exotic terraces were squoze together and moved north here too in the Siskiyous, at last count there are 15. Fascinating stuff for the non igneous student.
Long weekend here in Canada, finally some heat ,Red Deer River still at spring flow levels. Road to Dry Island Buffalo Jump P.Park washed out.Darn was hoping to get in some fishing .Spent most of the morning in the old river channels off the view point.Some very interesting rocks / flow patterns to this area as well as botany. Short Red Fescue Native Prairie most of the plants are at late June /Early July growth cycle. Wettest spring in 55 years.Grasses are high enough to cover up most of the Mule Deer we saw,just the top of their backs here showing.Yes I'm Dirt Guy.Nick great job with Gizmo, new microphone? Ellie and I are off in two weeks to Cypress Hills P.Park. Dude Ranch for a couple of days follow by staying at the Lodge at Elkwater for 6 days.Fishing Canoeing really looking forward to it.Both of us are essential workers.Stay safe WASH HANDS,FACE MASK when out side of your Cohort, please please. Under Armour has a washable face mask that is designed to work for Athletic use,bonus does not fog up our glasses. ♡♡♡Stay Safe.
hurray on your work for the exotic terranes, I am very glad to hear that. I live near Burlington Hill and it was my first researched location and I found you and learned that Cle Elum rock and Burlington rock are the same, just different sides of the slip fault. I learned about exotic terranes from you and my personal research has begun. Thanks.
So Straight Creek fault must run between French Cabin Mt and Red Mt then?? I always wondered why they’re so different despite being right next to each other. Please do Red Mountain next.
Such a beautiful area. So much to see including the fascinating geology! .... Heck, even a pretty good chance of spotting a sasquatch in an area like that! That's amazing stuff, especially re that 100 mile offset along the Straight Creek Fault! Fascinating! ...... cheers, Stay Safe!
Been loving these lives streams, previews, and vids. Haven't been able ot make a lot of the streams because of conflicts, but I"ve done my best to catch up on all the archived vids. I'm just wondering when we'll get our final exam and what will be on it....
I enjoy the Nick on the fly series for the views as much as the geology. What is the difference between Serpentinite and blue schist? Kudos to Liz for rescuing the hammer!
You are a great story-teller. And the story, Earth’s story, is awesome. Isn’t it interesting that the Earth itself evolved into human primates who explore our origins beyond ourselves, into the stars?
Another great program, Nick. Thanks so much for continuing to generously share your time and learnings! Two Quick questions, if I may: (1) If this was oceanic floor material that got shoved down into the subduction trench, I would think it likely to wind up like other ocean plate material you've talked about - melting down or becoming subducted broken plate remnants. What is the process that causes material like this to "jump" from being deep in the subduction trench to being an exotic terrain that's "docked" to the continental crust? And (2) Do we know whether material like this was shifted northward and *then* uplifted & exposed? Or was it uplifted to/near the surface and _then_ transported?
What a beautiful area Nick. I just love to see and learn more about our beautiful State. BTW Liz looks more like a Daughter then a wife. Take care...Scott
Since we are on lockdown again in our area, this was a much-needed virtual field trip. Thank you! Does look familiar...did we visit here during an NAGT conference?
Hi Nick ! One question I'm hoping you can answer since it wasn't discussed . How did the oceanic crust that was submerged into the subduction zone work it way back up 2000 ft above sea level . What brought it back up to the surface ? Thxs
@@amyspanne5629 , I think there is a significant difference between shale and blue schist. Olympics was ocean floor being scrapped off the edge of a subduction zone 50 million yrs ago . Pressue of the island and the subduction created a buckling effect across the state to Idaho. Nick says the schist dates back 120 million years ago . So if French mans cabin was created in the same process , I seems to me the rocks should have been compossed of shale. And if it dates back 120 million years the original continent would have been further East than it is today .
