We're all hanging out at Pilgrim Creek because that's where she normally first shows up.

I was with Tom, off a little ways, and all of a sudden he got a text like, 399's out.

- Here.

- Got it.

- Most of us thought, there's no way she's gonna have cubs.

She's getting older and it's really rare.

- [Sue] Here they come, here.

- And sure enough, here she comes with four cubs.

I said to myself, this is an amazing, special day.

(camera clicking) And it's incredibly nuts, really.

But that's the effect that she has on people.

- You saw four, right?

- Yes, I did.

- Four.

- Yeah.

(camera clicking) - [Reporter] Local celebrity, Bear 399, emerged from her den in Grand Teton National Park this week.

Delighting onlookers with a surprisingly large litter of four cubs.

- Grizzly Bear 399 - She's known as the matriarch or the queen in Grand Teton National Park.

She's famous for coming out with two, three cubs.

And now, miraculously came out with four cubs, which is very rare.

That's like a human having quadruplets.

- She's off-the-charts famous.

If you meet people out on the side of the road and, you know, and they're like, "Have you seen 399?

We wanna see 399.

Where's our best chance of seeing her?

We just wanna see her."
