Eric: "Yuka, you need to work on your precision" Yuka: "I am speed!"

The rock that you found is Mica. They were once used for windows.

As a few people have said, that mineral you found is a mica. Specifically it's a mineral called muscovite. that was a nice large one you found and likely means that there is a type of rock called a pegmatite in the vicinity. Pegmatites are similar in composition to granite, but have much larger crystals because they have a very high water and volatile element content and are the last rocks to crystallize in a granitic pluton. A lot of rare minerals are found in pegmatites, and pegmatite deposits are where a lot of our rare earth elements are mined.

those flakes you were wondering about is a type of mineral called Mica.

LOL, when your brakes sound like the clarinet section of a junior high band, you know it's steep.

Yuka in bc's videos. Quiet, does the jumps well. Yuka in her videos. "IM TOO FAST, AAAH"

Me expecting a biking video Bcpov DID YOU KNOW BROOMS ARE EPIC

Yuka, “I’m so fast!”, she’s the best.

Funny :) The Jürgenmeister trail actually does remind me of the steep, long hiking trails we ride here in (southern) Germany. Wish we had variety like in BC though :(

Lol why dad saw me watching your video and he said "Dang that looks soo fun" and I was like should we try it sometime? My dad response "heck yea" and in my mind omg yes

"the brakes are complaining" No, they're literally screaming lol.

My family bought a broom from there like 5 years ago, we still have it!

It makes me so jealous watching these videos. Im from Ireland and theres not many trails near where live.

Crushing it as always! I hope to be as good as Yuka one day, she's a boss!

The flakes you found are a type of mineral called Mica. I know this as they are my specialty. Love ur vids.

Your story development just gets better and better.

Can you start building again? I want to see the trail finished :D

Everything from the trails to the roads look absolutely beautiful! You can tell the angle of that first hill by looking at the trees compared to the ground - very steep indeed! Excellent trail and video :) "an unfortunate wasp incident" 😲

You found muscovite mica. They used to be used for making oven windows and now they’re used for glazes and paints. Wanna add a shine to that paint or a special coloring to your candles? That’s what it’s used for. They’re super thin and can be found out in the wild around gneisses and schists. My guess is that you’re standing on a bunch of shale that’s been hardened by the same hot crust that’s used to form the hot springs that are up there in the Kootenays. There’s also a bunch of limestone and sandstone up there. Be careful for sudden falling rocks, limestone or water burns and happy riding!

Your videos have been helping me get through recovery for my spiral fractured ankle so thanks for that!. The places you and your wife have gone are breathtaking! Can't wait for more.

“Lucky for us Antone and Isabel were kind enough to drive us up” YOU HAVE YOUR OWN FREAKING VAN GOD DAMMIT

I live in Kimberley and just started downhill trail riding and feels awesome to have someone like you come to bootleg

The flaky stuff is mica. It forms in sheets and naturally flakes off. It is a natural mineral.

you should go to mystic mountian, in bright, australia when covid is over. the best jump trail there has 53 jumps (53 jumps not including the b-line, otherwise it would be like 100 jumps) , 65 berms, 1 hip, 1 step-up to drop, 2 drops, 1 wall ride and plenty more. best trail in australia.

When the US is allowed to leave the country again I’ll have to go visit Canada. The broom shop looks nifty too. Now I want one. :-)

I believe it’s called Mica. We have a lot of it in New Hampshire.

That flat shiny material that you were curious about is called mica and is used in mold making, electronics, also in cathode ray tubes.

It’s so cool that you travel all over, I live about two hours away from Kimberley so I love that you are riding it

This is my favourite KZfaq video all week. Eric, your vids keep getting better and better. Excellent, descriptive trail analysis and “hands on” marriage counselling. I love seeing you guys travel around.

You’re such an inspiration!

That "paper like stuff" is a rock called "mica"... it's used in road building too. It's what makes an old road have a little shine to it..

Wow, great Video! I am always excited to watch your new videos!

The flaky ‘rock’ is a mineral called muscovite.... which is a type of mica. It used to be used instead of glass because its translucent. My great auntie had a beautiful antique lampshade that was made from sheets of muscovite. Thx for the vids!

Spider minding his own business swinging around full chill no worries at 5:41 :D

Muscovite Mica is the clear flaky mineral you picked up. Biotite Mica is its darker sibling found in rocks like granite. Next time you ride a rock roll in Squamish, check out the relatively large mineral grains (which is why Squamish granite is so good for grip on bikes and for rock climbing) and look for black flaky ones- that's Biotite mica. The crystals for Mica grow in platy structures, hence why you can flake it apart so easily, and are similar to clay minerals (I'm a PhD student in geophysics at UBC FWIW)

That flakey stuff is muscovite, a mineral in the mica family. You're likely riding on granite or granite-like rock that might be called a granite pegmatite since the mineral crystals are so big. Muscovite will form thin or sometimes thick "books". It's super fun to pull apart the flakes, right? Even the thinnest flakes are surprisingly quite strong and resistant to breaking when you bend them.

The stuff you found is called mica, it’s used as the glitter like substance in most makeups

I love yours videos so much keep up the great work ur my inspiration

The flaky mineral you found is Mica. It also used to be called eisenglass. I used to find it sometimes in my back yard in Byron, NY when I was a kid.

Since tree's always grow straight up towards the light, you can point out the angle between the ground and the tree's. It totally looked like those trails was 45°+! Keep the videos (Van Girl Yuka too) coming! 😎

Everyone says whistler and the Northshore and coast. But BCs interior is becoming king when it comes very nice trails.

That Pinch and Roll trail looked like a blast.

The flakes that you found on the Rock is called mica it’s really common on rocks where I live and when I was really little I used to collect it!😊

I'm a geology student in Chile, and that gray mica is a mineral called muscovite. greetings from here. Very good your videos!

Love your videos! You have consistently progressed and it has been enjoyable to watch! Thanks and keep up the good work. Cheers! 🍻🥂🍸

The flakes are Mika it’s a type of rock

everyone needs the spirit of Yuka in their life.

Mica is the collective name of the platey minerals which include; muscovite (clear), biotite (cola color), chlorite (green) etc.. large sheets of muscovite were used in Russia as windows as it was cheaper than glass. Muscovite was also mined extensively up to around the 1950’s and used in electronic capacitors.

That long steep hill reminded me of Penang Hill in Penang Malaysia. I lived there for 2 years and made numerous attempts to bike down the paved road and all attempts ended halfway in equipment failure and me walking the rest of the way. Caliper brakes heat the rim to the point where the inner tube fails. So I upgraded my bicycle to disc brakes but my tire pressure was too low so the tire and inner tube shifted backward on the rim tearing the valves off both inner tubes. The second time I attempted with disc brakes, the heat from the discs transferred to the cables and the brake cables snapped. It's just a long smooth paved road, but it's so steep, it seems impossible to ride non-stop from top to bottom without some type of bike failure. Honestly, this road is the steepest road I've ever seen! Nothing I've seen comes close.

Okay I'm a college drop out but I actually paid a little attention in historical geology. There are three kinds of rock. Sedimentary, igneous, and metamorphic. Sedimentary rock forms layers deep in the ocean floor. One example of this is shale. The ocean above the fallen sediment brings great pressure to bear over millions of years, and there's also heat coming up from the center of the Earth. This intense pressure heats up the lower layers beneath the sea bed and above the Earth's center, causing the sediment to get so hot it goes from solid to liquid and then recrystallize into pegmatites. These pegmatites or microscopic mica minerals between layers of sediment form from shale into slate. Sedimentary rock placed under intense volcanic like heat becomes metamorphic. So this tells me these mountain bike trails used to be an ocean floor many millions of years ago. Texas has a lot of that stuff too. We even used to have mica mines back in the day. Most of Texas used to be an ocean bed too, so you'll find lots of marine life fossils down here, and very little igneous rock until you get up into Oklahoma.

these trails look so fun!

Great stuff Eric 🚴 Sweet Trails buddy 😉👌👌

That mineral you found is mica, that particular formation is also called lepidolite

That flaky stuff is called Mica Muscavite it is a type of mineral that is very thin and paper like. There is also a type of mineral called Mica Biotite and it is the same just it is black instead of a white clear.

i always have a mini party when one of your videos come out!!!

Yuka is the funniest "Co-host" always a good laugh and smile when shes too fast for the trail

The rocky flakes that you found were the outer sides of a rock and back in the day they used that for windows

Those brakes sounded demonic 😂

Hey BCpov i'm one of ur biggest fans and it wold really mean allot to me if u liked or replied keep up the good work and keep sending dude

Bring back “today in BCpov” plssss

Dont know if anyone is ever going to read this but that flaky white transparent sheet you found on the ground looks to be a mineral called muscovite (also known as mica). It is very common in rocks and can be seen as shiny white specs in the rocks. The reason it looks like a sheet like that is because the atoms that make ut the mineral are aligned i such a way that that the atomic bonds are weaker along one axis than another, so when you split the mineral it is easier to split along the axis of the weaker atomic bonds. These bonds are so weak you can practically split them with your hands, as you did in the video.

I was in Fernie last week...a great place to ride and hang out! Kimberley is on my list for next summer...thanks!!

Muscovite Mica to be precise, often found in Granite, its what makes granite sparkle, there is a dark brown version called Biotite Mica

I hope he comes to my home town of fernie next. So exited

that piece of glass is called mica muscovite. It's a mineral and its present in too many rocks. I dont know the word in english but in my language (spanish) it's a mineral "petrogenetico" that means is this mineral is one of the principals minerals who can form a rock.

Love your vids u inspired me to start my own channel and build trails

I was in Kimberly for a ski trip. It’s amazing to see people standing in the exact same place I was

Eric -I haven't watched for one year or so and I must send sincere congrats for the progress in jumping (doubles !!)

That flaky rock you found is mica

It's Mica - they used to use it for the door 'window' on older wood stoves.

The flakey paper stuff is called mica, it is the most brittle mineral

I dont even mountain bike but I watch all your videos!

Awesome journey. And hose valley vieuws between the riding. Feel homesick to our trip in BC back in 2014 when I all see these footage🤩🤩 I bit crazy to say haha but you have a nice voice to listen to😃 I love the video’s🤘🏻🤘🏻 cheers from the Netherlands 🇳🇱

That’s mica, I used to have a few bigger chunks of it

Sweet looking trails! Good ride! 👊☺️🤘 Cheers from the east! YEEWWW!!!!

You pronounced the "Meister" pretty well ! Nice video like always

Broom shop!? Really cool 😅

I’m from Bentonville and you guys inspired me to mountain bike and now I mountain bike for three hours every day but you have to come back to Bentonville because we got some new trails

The way your voice changed when speaking to your partner is exactly how I sound talking to my Korean friend xD

Yep, Mica! Awesome mineral.

The sound those brakes made could be used in a horror movie

When your early... love the vids keep it up!

Never been into a video with no views, what an honor

Have a good day every one

2:12 your brakes sounds like they are about to create halo theme song

The forbidden Druid is a true dream bike 😍

The type of rock is Mica from I can tell from the video. We have large deposits in the National Capital Region. In the days when William de Champlain was exploring Canada Mica was used to make windows for homes.

If you want a trail system to really push you and test how fit you are go to Mount Kato in Mankato Minnesota and I could show you around sometime.

I really like you're forbidden bike,because I don't have a bike,but i really love you're vids

I loved the video, you both always do great ones. Regards from Mexico 🇲🇽.

Lots and lots of trail footage just how I like it! Ya gotta be Kootenay!

The trials are so goodly built

Mica is a golden or black flaked rock and they used it as a replacement for glass in lanterns and ship windows

He gets it guys. He gets it

mica is a part of granite. Mica Feldspar and quartz. granite is an intrusive igneous, meaning that it cools slowly and forms bigger mineral crystals.

Wait, so you're saying these Kootenay people have been mountain biking for 11,000 years? Amazing! :)

Will you be riding at the downhill park on Fernie? There is a new jump trail called rubber ducky that you should definitely check out

Canada is so nice when the summer

This vids are awesome rad watching u shred bc

Always love watching these videos!
