Some of the 22,000 concrete "Dolos" specially cast as sea defences, each one weighs 5 tons and is individually numbered so engineers can track any movement.

So I posted the giant's pencils, looks like you found the giant's game of jacks. Wonder where the ball is?
On a more serious note, for centuries sea walls have been built to control the ocean, but they finally realized that such structures concentrate wave energy in a small area at the base of the wall, almost always dooming the wall to failure. Then not so long ago, I think well after WWII (one of those pins in the passage of time) they tumbled to breaking up waves gradually, letting them dissipate energy through a complex web of channels and passages. Its somewhat akin to the oak tree versus the tall grass fighting the wind. Now such wave control barriers are limited by the durability of the materials used to make them rather than the ferocity of the sea crashing against the shore.

All correct, invented in South Africa I believe.

It's still more-or-less possible to identify this object, so I'll post the image here rather than on the abstracts thread.

Correct!



Interesting rock formations and layers, seen at one of the waterfalls I visited yesterday.

Uniform, thin layers of very fine-grained sediment such as that commonly (not always) indicate deposition in a lacustrine setting. A wet-dry annual cycle brings in a lot of mud with the precipitation followed by a dry stretch which leaves an extremely thin, commonly darker layer because of the greater proportion of organic material relative to sediment.



I especially like the last two images, BTW.
