It's summer in Yellowstone, and with soaring temperatures and drought comes the risk of wildfires. All the water from 'The Thaw' has flowed away and a lack of rain has left the ground tinder dry. When a major blaze breaks out in the Beartooth Mountains, wildlife cameraman Jeff Hogan scrambles a team to see if the family of Great Gray Owls he's been following all year has survived. The beaver family now has three young kits. But Jeff is shocked when their mother suddenly moves them out of the family home. It's a risky journey over dams and upriver and not something he's ever witnessed before.

Our cameras continue to follow the wildlife dramas in Yellowstone, and Spring brings many new challenges. While the brutal cold temperatures and deep snow of winter have gone, the weather is still erratic and there's the impending danger of the Thaw. When temperatures are high enough to melt the snowpack, millions of tonnes of water will cascade down the mountain, bulldozing everything in its path. Wildlife cameraman Jeff Hogan discovers a nest of Great Gray owls. There are three chicks, but one is a runt, significantly smaller than its siblings and at risk of starvation.

A Yellowstone winter is a brutal one. With temperatures that plunge down to minus 40 degrees Fahrenheit the wildlife has to find strategies to survive. Some animals leave, some hide and some tough it out. Grizzlies hunker down and hibernate, but this winter the temperatures have been erratic and some bears are emerging early. Finding food is a huge challenge, but our camera crews follow one male who's lucky enough to hit the jackpot and find a bison that's been released from its icy tomb down in the valley. But he has to hang onto it while the scavengers hassle him.
