News out of the high mountain West: The great white bark pine forests of Greater Yellowstone are dying. The majestic stands the stud the Rockies high peaks, with trees a thousand years old, are turning gray. Mile after mile of what they’re calling “ghost forest”. Half dead.

It’s messing with the region’s critical water flow. It’s driving grizzly bears onto human terrain.

It goes back to an exploding mountain pine beetle population no longer controlled by cold winters. It goes back to climate change.

This hour On Point: we’ll look at big trouble in the pine forests of the high mountain West.
