Okay, so I am leaving our little trailer.

We're kind of in our main staging area, which is pretty loud.

On the edge of Denver, Colorado is a giant flat, boring looking building, two or three

times the size of your average Walmart.

But inside, it's actually a scientific storage facility.

So I'm walking into the warm room.

Yeah, there's actually a really fun piece of equipment in here to warm up our hands

and eye glasses.

Kurt LeBombard is its curator.

And even in the summer, when temperatures are in the 80s, Kurt needs heavy winter gear

to work here.

That's because the collection he watches over is composed entirely out of ice.

Okay, so I'm going to go into basically opening a large freezer door.

It's about minus 26 centigrade, so it's not too bad compared to what I'm going to go

into.

This is the National Science Foundation's Ice Corps facility, a giant freezer where we

keep some of our most precious and vulnerable scientific artifacts.

The ice cores stored here were dug from places like Antarctica and Greenland, and scientists

use them to research the chemistry and the climate of Earth's ancient past.

All right, I'm going to go to back storage.

So I'm going to get the lights here.

In the back storage area, temperatures are kept at a cool negative 40 degrees.
