Those white cliffs are a dense Cambrian limestone.

To the cliffs.

Here's a piece of limestone.

Limestone pie and hot melted silver.

Would it give this block of limestone new properties?

And it's just limestone, nothing really special about it.

like buildings, antennae, bridges and earth meaning mountains, cliffs.

The core comes up as these cylindrical tubes of limestone.

And it's different than this limestone, you can see that.

And that's not snow that's what the white limestone looks like.

Now a block of limestone, in itself, isn't particularly that interesting.

We don't just want limestone dumped everywhere in all the pretty canals.

Now, at the base of the high cliffs there's this natural cave.

A storm was rising and the boat was drifting towards the cliffs.

And Lost City was characterized by these incredible limestone formations and upside down pools.

The dip slopes in the overlying limestone, the orientation of the flora, shallow waters...

North rode donkeys, scaled cliffs, and crossed swamps to reach the plants she wanted.

And so here the protocells are depositing their limestone very specifically, around the foundations of Venice, effectively petrifying it.

But gradually, as the buildings are repaired, we will see the accretion of a limestone reef beneath the city.

If you go up on top of those cliffs, that's some of the Long Now land in those trees.

But imagine what the properties of this limestone block might be if the surfaces were actually in conversation with the atmosphere.

It was Crease Limestone, and that was produced by sea creatures 350 million years ago in a nice, warm, sunny atmosphere.

Landscape ecology concerns itself with how the stream and the meadow and the forest and the cliffs make habitats for plants and animals.

And if you look even closer, you'll see, in that limestone, there are little shells and little skeletons that are piled upon each other.

This is our protocell technology, effectively making a shell, like its limestone forefathers, and depositing it in a very complex environment, against natural materials.

The base of those cliffs are covered in poison ivy, live oak, sumac and a thousand plants with thorns as big as my dick.

Now, I happened to be on the radio with Alexander when he got to this point at the base of the cliffs, and he said, quote,

And architect Christian Kerrigan has come up with a series of designs that show us how it may be possible to actually grow a limestone reef underneath the city.

And you can carry right on up through meadows and steepening forest to the high base of the cliffs at 10,500 feet, where there's a bit of a problem.

I love how they were able to preserve most in everything that makes you feel close to nature butterflies, man made forests, limestone caves and hey, even a huge python.

And as you come from the north, it is all masonry growing out of the sand cliffs as you come from the Himalayas and evoking the tradition of the fortress.

It's this beautiful world all of its own, surrounded by cliffs, and it's an easy hike to stroll up the canyon bottom, until you get to this barrier, and it actually presents a problem.

Bring me blocks of iron. So that, when he had leveled up between the two cliffs, he said, Blow. And having turned it into a fire, he said, Bring me tar to pour over it.

Give me pieces of iron till, when he had levelled up (the gap) between the cliffs, he said Blow! till, when he had made it a fire, he said Bring me molten copper to pour thereon.
