That was oddly satisfying. I think it would be even more satisfying if it was just a static tripod shot from a good angle.

Littoral fish are usually adapted, and going from fresh water to salt water and back is often part of their breeding and life cycle. See: Salmon.

why is stuff like this so fascinating? I could watch it all day.

also, oldy but goody not nature taking its course so much as nature schooling silly humans on building pit mines so close to the ocean.

Water plays the long game. Never bet against water.

Thousands of gallons of seawater breaches the mine creating a spectacular show of force.

It's funny, I think the guy says the same enormous understatement of volume in the first river breach video . A thousand liters is just one cubic meter of water, right? There's a whole lot more water moving here......

This happens regularly, I think, it's a relatively shallow river meeting an ocean current that brings in sand? From the map/satellite it's not like there was a lower reach that this break-through stranded, that's just the mouth of the river.

“How did you go broke?”

“Two ways,” Mahlongwa said. “Gradually and then suddenly.”

When I was a kid, I loved the process of the spring melt. We were in a valley, so as the snow melted it would form channels in itself, twisting and changing and reforming itself as the water gradually made its way down. (Not always naturally - as a kid, I did not have the patience to just watch, and tweaking the snow here and there to help the water flow was a big part of the fun.)

There was nothing nearly so spectacular as part 2 of this breach, but there's still something inherently fascinating and satisfying about even a little stream of water transforming itself as it flows.

Wow, this was crazy. I wonder how he knew this was going to happen then, or if he just happened across it, or if between video 1 and video 2 he helped that channel along at all in any tiny way. So fascinating to be there right as that was happening, and in such a short time frame.

Kind of a waste not to surf it like they do in Hawaii.

It must have taken so much self-control not to start damming up the initial trickle.

Lovely piece. Thanks!

For me the best was that first tiny trickle winding its way across the the sand. Then, après moi, le déluge...

The river to the ocean goes, a fortune for the undertow.

That was gorgeous.

When I was an avid hiker, I met the cinder cones of California. They are incredible! Just imagine, solid stone twisted like the Devil's Postpile. It's amazing the life we live on! (And OMG: the Racetrack!)

Jeepers!

Started to get worried for him towards the end. The tide was clearly coming in, and he mostly had his back on the waves...

Geez, does anyone else start getting anxious towards the end of the second video where he is STANDING on the collapsing bank?

What I really did not expect was the micro-Niagra like arc of falls eating back into the bank-adjacent riverbed.

Yeah, I mean, I guess since we're seeing the video, he survived, but jeezy creezy, my hand to Bob's Eternal Pipe, I thought he was a goner there at the end.

SO South African. "It's ABSOLUTELY freezing here! It's about, oh...11 or 12 Celsius!"

Now I am homesick for a place that isn't home. Been to that location. But I lived over-looking an estuary, in South Africa, and watched it swell, and then flow, many times.

Part 2, six minutes in: "Where I'm standing now, I'm below the water level of the river, standing on the rocks here"

From that point onwards I was wondering how long it would take him to conclude that this was perhaps not the greatest idea he's ever had.

Quite glad he eventually did, though. Well, I'm just kind of assuming that this isn't footage retrieved from a phone washed up on a beach somewhere.

Youtube's algorithm led me to this flash-flood watcher (and his wife, and his buddy, and "Now, go!") in Utah.
