Monstrous Flash Flood & Debris Flow l Johnson Canyon, UT 7/16/2018

That must have been one hell of a cloud to hold that much wood.

Man, I can't imagine the raw power this is producing in-person. most likely feel the ground shaking. It amazes me how mother nature shows its true power.

Wow, the amount of force necessary to carry that weight of timber, mud and water is extraordinary.

Thanks for this. I never would have thought so much debris could be carried by so little water.

How beautiful: Newly spawned twigs, migrating to the ocean. In a few years they will be branches, ready to swim back up the dry river bed to become trees in the same place they started their life as a twig. The circle of life.

I grew up in the desert and was always warned about flash floods. We used to speed into the huge black thunderstorms on our motorcycles for the sheer exhilaration of pouring rain, black skies with blazing lightning and often big hail, roaring wind and sand and water. Amazing. In the desert that doesn't happen often, but when it does it is spectacular to be in it. Never did we see a flash flood. When I look at this, it is like that is a slow motion, deathly, grinding machine coming down the arroyo, and no one would stand a chance if caught in that mess.

That's just incredible! All those trees! Ty for uploading this. And for showing the dangers and power of the weather. I'm amazed how quiet that debris flow was. Makes it even more dangerous. Stay safe.

I remember learning about massive debris flows like this as being the real eroding force that formed the canyons (including the Grand Canyon). Most people think about erosion coming from water flowing over the same area over time, but when a valley/wash is dry for a long time and then incredible heavy flows in a short period, flows like this with water, trees, mud, and even giant boulders move at a rapid pace eroding the dry soil beneath them quickly. The low spots become the obvious path for subsequent flows, and more erosion, on and on for millennia until you have the spectacular rock formations we see in the drier parts of the world.

The sound of the water flowing with the sticks breaking is very relaxing. It should be made into music for meditation, study, or sleep.

I'm amazed how quiet it was, 100's of tons of trees moving at speed. You would think the noise would be deafening.

The sound of those flowing branches getting crushed is terrifying. So much force!

I'll never forget hiking the Virgin River Narrows several years ago, and all the warnings about flash floods. The most compelling one had a photo of an enormous debris flow, with the caption, "I can just swim my way out." Obviously targeted toward those who (like me at the time) have no idea of what a flash flood actually looks like.

Somewhere downstream, "post 10" is going to need a bigger rake.

Legend has it he's still standing there saying, "WOW!"

Fall into this and you would get skewered. This is something you probably never see in a lifetime. Really cool video! Mother nature can be a real mother.

Incredibly cool! It's amazing to see so much debris carried downstream...I'd love to see one of these in person!

Dude, you're amazing to have kept ahead and shot so much footage, never seen anything like it before, thanks a billion for posting and showing what is going on in nature. Amazing footage. Hats off to Reed.

I live in Las Vegas, NV and a couple years ago my husband and I were at the "Wetlands" when we noticed the sky was turning pitch black in the Northern area of Vegas we saw lighting and heard thunder but it was sunny where we were. All of a sudden we hear running water and notice that the wash had risen so we decided to head to higher ground from where we were. I started hearing some snapping noises then creaking and then what sounded like wood breaking but I can't figure out where its coming from. Then I see a tree starting to sway. I thought it was from the water and debris hitting it. NOPE it literally uprooted this 50+foot tall tree and swallowed it whole and then another 10 or more trees the same way all this happened within minutes after we decided to get to higher ground and somewhere i got it all on video. It was CRAZY!

im australian and thanks for filming this this is awesome wow we dont have things like this over here but this is frickin unbelievable 😳😧

There must be a lot of weight in those logs and twigs, so it shows just how strong that water flow is! Amazing!😊👍
