June is one of the most dynamic times of year in the Greater Yellowstone ecosystem. Life emerges from months of bitter-cold winter. Flowers are blooming, rivers are rushing and Yellowstone is bustling with new life. As Yellowstone National Park and its environs awaken, cougar cubs venture out from their underground dens, black bear cubs learn to hunt and bison must protect their young calves from hungry predators. There’s spontaneous drama unfolding everywhere at every moment.
