Phil ChenevertNARRATOR
The cliffs were interesting.
Phil ChenevertNARRATOR
Limestone, evidently, as expected, but rather dense at that.
Phil ChenevertNARRATOR
Maybe some barium replacing the calcium? Or was the gravity different enough to destroy his judgment for such a small fragment? Probably not.
Phil ChenevertNARRATOR
He was actually using inertia more than weight in making his estimate.
speaker_0NARRATOR
For a geologist, that transition can be extremely revealing.
speaker_0NARRATOR
Limestone says one thing.
speaker_0NARRATOR
Thick layers of rapidly deposited sandstone and conglomerates say something else.
speaker_0NARRATOR
The sedimentary environment is responding to nearby tectonics.

speaker_0NARRATOR
A location can therefore spend millions of years quietly accumulating sediment and then eventually become part of the mountain range itself.
speaker_0NARRATOR
The advancing deformation across the greater Audrea margin produced stacks of sedimentary rock that now form major portions of the Danures and Helanites.
speaker_0NARRATOR
Limestones that had originally been spread across wide marine platforms were compressed into much narrower zones.
speaker_0NARRATOR
This created some of the spectacular carbonate mountains that now dominate parts of the Balkans.
Heather M. ByeNARRATOR
Then follows Gebel Abu Faida, dreaded by the sailors for its sudden gusts.
Heather M. ByeNARRATOR
Limestone predominates throughout, white or yellowish, broken by veins of alabaster or of red and grey sandstones.
Heather M. ByeNARRATOR
Its horizontal strata are so symmetrically laid one above another as to seem more like the walls of a town than the side of a mountain.
Heather M. ByeNARRATOR
But time has often dismantled their summits and loosened their foundations.
Vinnie SammartinoGUEST
See, that's the thing that I always had a key with.
Vinnie SammartinoGUEST
I mean, the outer facing of the Pentagon is made out of limestone.
Vinnie SammartinoGUEST
Limestone is one of the softest stones there is.
Vinnie SammartinoGUEST
Are you going to tell me that the limestone at the Pentagon held up to a vertical stabilizer of a jet, but the steel box columns at the World Trade Center didn't?
VyzygothHOST
When has physics changed? I don't
speaker_7NARRATOR
The decision to abandon a monolith could have happened quite late in the process.
speaker_7NARRATOR
Limestone is treacherous.
speaker_7NARRATOR
As you cut down along the sides and undercut the base, internal flaws reveal themselves.
speaker_7NARRATOR
A hairline crack can propagate across the block.
35 MINS LATER
speaker_7NARRATOR
The result, once the grains finish compacting, is a remarkably close-fitting joint, even if neither surface was machined flat in a modern sense.
speaker_7NARRATOR
Small wedges and shims do the rest.
speaker_7NARRATOR
Limestone or hardwood wedges can be driven under the block's edges as it comes off its temporary supports.
speaker_7NARRATOR
Tap a wedge.
Dayna KathanHOST
But it makes sense.
Dayna KathanHOST
Limestone is one of those stones that can hold a recording of energy.
Dayna KathanHOST
So when I was living in this apartment with my two roommates, one of my roommates, we'll call her Ray, decided to do a ritual blessing to bring positive energy into our apartment.
Dayna KathanHOST
Pretty soon after this, weird things started to happen.
Herman PoppleberryHOST
Certain stones age beautifully.
Herman PoppleberryHOST
Limestone gets a mellow, weathered surface.
Herman PoppleberryHOST
But it also erodes in acid rain.
Herman PoppleberryHOST
Marble does the same.
ChristineGUEST
But the quarry here, the stone from it, we know of two buildings in the village for sure that were built from the stone.
ChristineGUEST
What kind of stone were they? So it was Limestone, I believe.
ChristineGUEST
So the Derby residence, which is now Lake and Main.
ChristineGUEST
So that one 100% was built from stone from here.
speaker_2NARRATOR
Luckily, the subsoils of Tikal were packed with an easily accessible and endless resource.
speaker_2NARRATOR
Limestone.
speaker_19GUEST
The Maya exploited the limestone in different ways, not only for construction material, but also for tools.
speaker_19GUEST
The core of the limestone, it's very hard.
