‘Nick From Home’ Livestream #33 - Ice Age Waterfalls

[@dannymccarty6680]

This strikes me as one of the very best of the “Nick From Home” presentations. Beautiful aerial photography, dramatic land forms, graphic animation - all brought together by Nick’s magical story-telling skills. Impressive. Ya’ gotta love it!

I am so sad I always miss the live streams! My boys are 1, 2, and 3 so they pretty much have to be asleep for me to watch anything I actually want to pay attention to lol So grateful I can binge watch after the fact! Thanks Nick!

>What prop would you use from the kitchen Answer: Sugar Cubes, seems like a great analogy for the vertical walled tootsie roll blocks being able to be hauled away, and flat bottom surfaces left behind. Alternatively tall 2x2 lego block columns pushed out of the way by hand to represent the water carrying away the segments of and full columns, which can also be used to show the pairs of falls and steps that are created at resistant layers. Thanks Nick, I hope these live streams are as good for you as they are for us right now, with out a doubt the most positive thing that has come from this, been watching you for quite a while, and absolutely love what you do! Thank You!

[@markt113]

The good news: you have answered hundreds of questions that I had about the geology of this area I love to visit. The bad news: I now have a thousand more questions! I guess I better keep watching. Thanks Nick!

[@1234j]

Excellent, Nick. Amazing animations! Great talk. Cheers from Hereford in UK.

[@tikitiki7610]

love you and your videos, trying to catch up.

[@JustOneAsbesto]

Thank you, Nick. That's very sweet. I LOVE YOU TOO!

Thumbs up from New Braunfels, Texas - Thanks

[@mmk5638]

As always, a great episode (wish I could have been a cake zombie - lucky locals ❤️) REALLY interesting - now gotta go make French toast and play with butter ... ps - thanks for two more cool you tube channel suggestions 👍🏼

[@larrygrimaldi1400]

i aw this live last April, but now I appreciate the great footage---, and the reasons for the block canyons. NOw that nobody can take their usual European vacations, the Dry Fall Park should spend a bundle on marketing how this geology (safe from Covid) happened.

[@jamespmurray4059]

How did I miss this??? I’ve seen every other episode. This is my favourite topic, but that’s like saying it’s my favourite song.

[@brucewitherbee7124]

We owned 5 acres in Terrace Heights a few years ago on St Hilare st at 2150 feet elevation and it was littered with large boulders of solid Basalt. You lecture on Ice age floods explains how those bolders got there. Also there is not a trace of any soil whatsoever on the property as it is covered with solid Basalt over 230 feet thick, as we learned from the drilling samples from the 250 ft deep well. Because this Basalt layer was so solid, grading of any kind was impossible.....

[@CAMacKenzie]

Watching this again it occurred to me to wonder about something. 16,000 years ago sea level was lower than today, something like 110 meters down. How far beyond the present coast did the Grand Ronde lava go? Certainly I would expect to see basalt some distance out from the present coast and if it reached the sea of that time, there should be pillow basalt out there.

The power of flowing water in floods can create awesome grandeur in the landscape. Or it can create magical slot canyons that paint with light and shadow. Antelope Canyon in Arizona is on the bucket list as is the PNW. The features of the Channeled Scablands Are the product of the the last time we warmed from glacial period. I wonder if any of the features in the area had begun to form during the beginnings of previous interglacials. Mapping of the English Channel has revealed similiar features

[@KimRBrown]

I have a copy of that American Geological Society publication by J. Harlen Bretz! Picked it up at a little bookstore years ago. includes stereoscope view cards.

[@lorrainewaters6189]

Why is the Grande Rond more resistant to erosion?

[@ericramos3416]

Once again! I am down the habit hole....this is brilliant! I wish I could have animated that flood, for you. I would have included all the crap floods bring, which also has an errosive effect on the landscape.

Nick you should be mandated to add a disclaimer to your shows: "No German Chocolate Cakes were hurt during making of this show."

[@michaelnancyamsden7410]

Do not be concerned about the time you take. It is interesting. I am patient.

[@wesmahan4757]

Couldn't watch live. But a question: Why is the Grand Ronde basalt so much harder, or more dense, than the other flows? (I'm thinking about the mineral content of the various flows.)

[@sent4dc]

He said it in the stream. There's more of it and it is thicker.

[@dadskrej5226]

Also, the basaltic floods of lava were thicker in consistency than the Grande Ronde lava which was thinner (soupier?). The Grande Ronde floods of lava, being thin, flowed over vast distances compared to the basaltic lava that was thicker and flowed much less distances.

[@bagoquarks]

NOT A SUBTITLE: Rather a YT link relevant to a question asked in Nick's #33 Q&A. There are some impressive high definition sonar scans of the English Channel seafloor showing features very similar to the Scablands, which are referenced at 7m43s. English Channel sonar starts at 17m24s. "Megaflood: how Britain became an island" kzbin.info/www/bejne/ioiYeX2NiNV_jac

About Bretz's students not following him--- Well, how many of Galileo's students followed him? They didn't want to be excommunicated--- it's the same impulse, whether it's the Church or Academia.

Nick here is what I found for the UK ice age floods, www.the-stonehenge-enigma.info/2013/05/european-mega-floods.html

[@Ryanboy2020]

Nick, you can add up all of the ice age lakes, Missoula, etc.. and you still do NOT have enough energy to create the kind of erosion you are speaking about. In other words there isn't enough mass (water) frozen in these ice age lakes to account for the wide spread devastation that we see in the geology. These floods were 400 feet high traveling at tremendous speed as a result of one or more of the ice sheets that were covering the northern hemisphere being melted suddenly. This was a sudden and dramatic flood in geology terms possibly within a 2 year time period all the devastation we see could have been caused. Now what kind of energy could cause one or more of the 4 mile thick ice sheets covering North America to melt? That issue is up for debate but we do know that 10,900 years ago there was a massive catastrophe that effected the entire hemisphere, possibly the entire planet tied to the Younger Dryus period. "The Black Mat" now seen around the world when geologist are digging in the field at the level of 10,900 years ago, confirms that a catastrophic event did take place with massive flooding and global fires. I suggest you look at CosmicTusk.com for further information regarding the latest theories. The most likely scenario is that a comet broke up in our inner solar system 11,000 years ago and that massive pieces of the comet impacted the Laurentide Ice Sheet near Greenland which caused the immediate break up of the ice sheet with some ice being vaporized, other pieces were blown into the air several hundred miles and millions of cubic feet of water were instantly released causing massive flooding that we now can see evidence of in our PNW geology.

SLOPES! Topography. Seeing maps in 3-D is a tough thing for people to do without lots of training?

[@janerussell3472]

Let's not mention the Biblical Flood. lol. It looks like those pillar lavas ARE aligned horizontally, just like honeycombs. But without being in the field, I wouldn't swear to it.Why they're hexagonal is a physics question. The honeycomb conjecture states that a regular hexagonal grid or honeycomb is the best way to divide a surface into regions of equal area with the least total perimeter. Another physics question would be why bubbles ( of soap ) are spherical. But now we're way off topic. That would apply in hot mud or magma areas, like Yellowstone, I suppose.

Another superb presentation by nick
