Great Yellowstone Thaw

PBS | 9:00 pm

Spring comes to Yellowstone National Park in the second episode of this new miniseries, allowing the environmental perils of winter to dissipate. However, there’s another series of threats to the area’s wildlife as the seasons change — including the thaw that sends water rushing down mountains, posing danger to those situated beneath it. Beavers are especially endangered, though the occasion also brings with it the potential to generate new life.
