And for the record, it's open to the public still, mostly.

So if you're ever in Northern Spain, go, because I don't know how much longer they're going to leave it open for, but it is extraordinary.

It is up on the side of a little, I mean, they call it Monte Castillo, but I'm from Canada with the Rockies.

So it's a cute hill.

But it's a hill overlooking a very important valley where there would have been herds that moved through during the Ice Age.

So this is northern Spain, inland, not too far from Altamira, that kind of region.

What we have is that El Castillo at the time, it was a big cave mouth with a huge overhang.

So a lovely place to live if you wanted to be up where you had a good view, you could see the herds, you could see things coming, you had good cover there.

But again, keep in mind, people don't tend to live like inside caves because they're wet and drippy and muddy.

But they often will live in the entrance or near an entrance, right?

Because it provides some shelter.

So that's kind of what we're dealing with at Monte Castillo.

So Monte Castillo, if you go there, the entrance is fascinating because they've been excavating there for decades.

And the scaffolding drops like at least 30, 40 feet.

People lived there in the entrance for like 150,000 years.

So this is like way before modern humans ever got there.

Neanderthals, and again, Kimba didn't necessarily live there all year round.

Maybe some did, some didn't.

It depends on what's happening with the Ice Age weather around them.

But people lived there for 150,000 years.
