Why Are Grizzly Bears Flocking To Ancient Volcanoes?

Wyoming grizzly bears seem to know how to find the calderas of ancient volcanoes.

Somehow they always go right for them.

HOW? WHY?

Wyoming geologist Myron Cook has released his latest video on YouTube.

This is part two of his exploration of the Wyoming Absaroka Mountains.

There were many volcanos throughout this region over time. Not just one big one.

In this video, Myron explains how to read the story in the rocks and why the landscape looks the way it does today.

He also answers the question as to why and how these bears know where those old volcanos are.

Watch his video, below.

The reason is something that we humans often walk right over if we are up there.

There are more moths up in those rocks than you can imagine.

Grizzlies go up there to search among the rolling, loose rocks for a treat.

These little moths are a source of protein. It helps those big bears to fatten up before winter.

Biologists estimate about 200 bears each year feast on moths in the eastern portion of the carnivores' range.

Each gram of moth offers bears about eight calories, which means some bears will eat up to 40,000 a day.

Myron's video also turns back the clock, taking us to Wyoming's past when the landscape and climate were much different than what we experience today.

In the video you'll see a few petrified trees. But you'll also be surprised to see how many there are below ground, out of sight.

These changes are natural, unpredictable even by our modern methods, and forever changing.
