Alex Honnold Rappels The Moulin | Arctic Ascent with Alex Honnold | National Geographic

[@fab1000]

lol, honnold lines are always gold " he is so handsome he must me very capable" Other than that I would definitly rappel into a moulin with a drysuit instead of mountaineering clothes...

[@sunnyinvladivostok]

drysuit companies aint sponsoring this video lol

[@drheidisevestre]

What a great experience that was. Please let me know if there are any questions on the science we did on the trip! Happy to provide more info :)

[@VinDieselS70]

Looked amazing. How much water is normal underneath a glacier? I know you can see plenty of glacial tracks on the rocks in Sweden and what direction the ice was going but what impact has the water on the underlying rock? Theoretically more water should leave rock smoother. Like the difference with fine grain sandpaper vs coarse sandpaper, if you know what I mean?

[@thaidollas]

Why was it necessary to rappel down in order to deposit the piezometers? Thanks!

[@Travizeno92]

I couldn't believe the journey you went on up there! You should make a youtube video on things you learned.

[@JoRoWi83]

I’ll never get enough of Alex The dude is just what every person should aspire to Live fearless and deny self doubt to creep in

[@roketynoramallorca2882]

and I'm so happy that he gave up climbing free solo.

[@stevenbartlett5867]

Thats so beautiful! Super dangerous but impressive.

[@lentitudes]

OMG I wish Leclerc to be there :( his soul is with you guys. Amazing!

[@juliaitbaeva8530]

Wow! I just don't have words to express how it's unbelievable and cool!

[@Consider_Blue]

Right! 🤯

[@JGH2015Sara]

Goosebumps!!❤

[@Travizeno92]

I got disney plus and watched this and it was well worth it i thoroughly enjoyed it. I wish it was longer but it was 3 episodes so it wasn't short.

[@AnimalShow-99]

😮 so dangerous, feel in the ice tube.

[@MikeySkywalker]

The way they’re just standing on the edge is scaring men

[@dinh5532]

Alex is so funny but he and his wife are right, Aldo Kane is a stud!

[@itslogical3884]

very handsome, but not a 2x4.

[@aaallllen]

Looks epic. This type of footage is where TNF gets value in their sponsorships.

[@nathanesau1]

Release this in Canada please

[@jameskrueger8356]

why did they rappel down just to drop the thing on a wire? couldn't you just have done that from the surface?

[@itslogical3884]

Yes, you are right. But a lot more viewers will watch the video this way.

[@Hunyango_007]

@@itslogical3884 that was such an ignorant response and ironic considering your yt name (logical) lol! they are also getting samples of ice from glaciers in different layers, and that is nat geo right there, Not a group of youtubers. A group of experts of various studies assembled, you should know if you actually study stuff and watch these kind of documentaries or maybe just have common sense.

[@FaceMaster_Almaty]

It's everything good, but i didn't understand , for what they do it that ? Any one please explain me?

[@vincevincent6984]

Crazy 🆒!

[@LenGarageGym]

When will season 2 come out>?

[@strainddgrayvee]

Ridiculously dangerous at the start I was thinking imagine putting a stick of TNT down it boom closed 😅

[@chrisoulalakkas7935]

Life is a single-player game. The more you level up, the better possibilities and people you meet.

[@mypalfootfoot9591]

So true!

[@luceinbattaglia9425]

🤓Ok! ….now I know Alex is the best candidate to find Agartha!👏🔝🦾

[@Flying_Snakes]

Ummm, couldn't they just lower the measuring device with a longer rope instead of repelling down to do so. Ya know, for like safety and stuff.

[@drheidisevestre]

it was certainly pretty tricky. We wanted to make sure that the instruments were dropped in the right conduit, hence we had to rappel as far down as possible..

[@Flying_Snakes]

@@drheidisevestre Makes sense. Super dangerous but valuable info.

[@EnoughBull]

Alex is awesome but there is absolutely no reason anybody needs to make a rappel that dangerous. It's not like the information has any use except satisfying curiosity. You can't change that glacier. Just enjoy it from above, no need do go down inside it. They would go diving inside a volcano if they could. Still watching this, though.

[@JOEARLOPO]

Alex bi energy is life

[@Aquwert]

it's beyond sad to see a glacier melting like that and it's happening all across Earth

[@DanHooker-z9g]

It’s really not sad at all. Earth will be covered in ice again one day don’t worry

[@RaveMasterr]

Whether there are humans or not, that will still melt. Then after some millenia will freeze again, just a cycle.

[@jordanthoms887]

really? u rather watch water become ice?lol the glaciers have been melting for the last 13000 years , there was 2km of ice over most of canada 8000 years ago

[@storm2000808]

​@@jordanthoms887Scientists are probably more concerned about global warming and not the long term natural effects of melting ice.

[@jordanthoms887]

@@storm2000808 lmao i love it, hilarious u know what happens when the globe warms? ICE MELTS! lol U know why ice melts, global warming u know these are two natural processes? our glaciers have expanded and melt 6 times over 400kpa also it wasn't long ago that our mega fauna died off, 6 ft beavers, mammoths, massive bison. These fauna made up the vast majority of our food sources. Than we lost it all, of our food sources, we were forced to adapt and grow crops, such adaptations lead us to be the most versatile and wide spread species in the world, oh how terrible global warming is u know when russia becomes a beard basket, canada becomes a fruit basket, alll of our northern regions ( where most of our landmass sits) turns from tundra to growable climates, yea real bummer climate change drives our adaption and changes as a species, we react to it, we are only in such a situation because we are in the longest interglaciation period we have experienced in our existence ( though we have gone thru many) so we should be basking and enjoying our time under the sun, dont let the fear mongers make u hate such a bountiful time of our existence, most of human history has been spent in the shadow of glaciers and exploring frigid wastelands

[@user-cw3nb8rc9e]

He is asking for it. Asking for it so much.

[@Alphaswings]

I have more respect for Hazel on this trip to be honest.

[@AntonAdelson]

Hazel?? Where??

[@johnlorenzo4212]

Why didn’t he free solo it?

[@obi-wan3916]

Thrill seeking with a science veneer. Just call it what it is.

[@drheidisevestre]

Please let me know if you need more info on the science we did during Arctic Ascent. We worked with 12 research instutes and performed 18 different experiments during the expedition :)

[@mmmountain1968]

u couldn't pay me enough to do that

[@natalieranguy648]

Scientel🎉

[@loober]

RIP Alex

[@mypalfootfoot9591]

???

[@AtortAerials]

That was boring.

[@Smoothjaswi]

Lets not pretend that was for science. That was exhibition not expedition. A) The ice isn't sliding on the water unless the ice is completely detached from the rocks. B) You can measure the meltwater output at the terminus of the glacier.

[@SensitivityIsland]

Wont be long before Alex isnt with us..Risk levels just silly. Poor guy. Poor wife. For science? Yeah right.

[@janm2473]

DID ALEX GET PAID TO DO THIS? 😆

I mean this was obviously cool because it succeeded but had it failed.... This is undeniably one of the dumbest things I have ever seen humans attempt in my life. This is right alongside Titan submersible stupid

[@Consider_Blue]

Titan is hard to beat…

[@PrestonIV]

This was child's play and a cake walk for Alex compared to free soloing El Capitan with no ropes.

[@drheidisevestre]

Hi! This is a technique that is used quite often in the Arctic. We would not have done it if it had been too dangerous :)

[@nighttrain1565]

@@drheidisevestre idk, I think the look on Alex's face at the end of the video after he discovers the amount of water flowing underneath of him explains it all lol. Everything is fine and dandy until you figure out you are on top of a river lol

[@drheidisevestre]

@@nighttrain1565 yes it certainly us a loud and dynamic environment.

[@torceridaho]

i am suspicious of the science used, since it was not explained, or verification of a technique used elsewhere. I get the uneasy feeling they were just exploiting peoples' fear of serious environmental change. Such a controversial topic, this seems like almost a promotional piece...

[@freakyfridayfun]

What sience that wasn't explained are you referring to?

[@torceridaho]

the instrument she used for purportedly measuring depth. and what is the correlation between depth and the movement of an iceberg. nothing explained. @@freakyfridayfun

[@jontomassi]

GIS student here, they used radiometry and multi spectral scanners to detect most of their data. Certain wavelengths of energy scatter when they hit objects, this scattering produces data we can use to create imaging information. Producing spectral data for moulins is important to glaciologists because the volume of the water beneath the glacier can determine the speed of the glacier’s basal drift. Basal drift is a key factor to glacial melt and sea level rise.

[@torceridaho]

that was very informative and helpful. so I assume there are plenty of studies on the correlation between basal drift and water volume? thanks @@jontomassi

[@mendiethegingerfam5521]

I think it is wonderful that people risk their lives for science.

[@wvbo]

honestly i don’t understand fully why it’s a problem that the glaciers are melting faster does it affect wildlife? what wildlife is in these mountain regions that couldn’t benefit from water? are there towns being affected by the glaciers melting? to me it would seem immature to believe the mountains and the earth would be affected by this climate change is so selfishly human that it’s hilarious
