PAUL RAEBURN, host:

Okay, I'm rushing now. I'm rushing because it's time, ladies and gentlemen - do we have a drum roll? No drum roll. Cue the excitement for Flora's Video Pick of the Week. Hi, Flora.

FLORA LICHTMAN: Hi, Paul.

RAEBURN: How are you?

LICHTMAN: I'm pretty good.

RAEBURN: So what's on the silver screen, so to speak?

LICHTMAN: On the small screen this week?

RAEBURN: On the small screen.

LICHTMAN: This week, we have a field trip video. SCIENCE FRIDAY went to, I'm would say, like, a really pretty neat geological wonder.

RAEBURN: SCIENCE FRIDAY goes camping.

LICHTMAN: Yeah.

RAEBURN: Something like that, yeah.

(Soundbite of laughter)

LICHTMAN: SCIENCE FRIDAY gets sprung from the office.

RAEBURN: Right. Good. Always good. Yeah...

LICHTMAN: Just as in time...

RAEBURN: ...there's oxygen out there to breathe. Despite global warming, you know, still fresh air out there (unintelligible).

LICHTMAN: That's what I hear, and found out this week. So we went to this - the state park in northern - northeastern Pennsylvania, Hickory Run State Park. And in a shallow valley within this park is a - it really looks miraculous. You drive up this little dirt path, you get to a clearing in the woods, and you see 16 acres of sandstone boulders. It's just a vast expanse of rocks. And so we caught up with one of the environmental educators there and found out the story behind this weird geological feature.

RAEBURN: And you call this where boulders are born?

LICHTMAN: Yeah. That might be, sort of, overstating it or misstating it.

RAEBURN: I know what you're - thanks for saving me from saying it. I don't believe it for a minute.

LICHTMAN: Well, boulders are born there. I mean, they do come from bedrock and then they did collect there. But there's a longer story that you can hear and find out on our website.

RAEBURN: All right, great. If you want to know more, check out the website. Flora Lichtman is multimedia editor for SCIENCE FRIDAY. Thanks for taking the time to tell us about it.

LICHTMAN: Thanks, Paul.
