The changing season brings out the best in Yellowstone. The critters tend toward the frantic: the bull elk are madly trying to keep their harems in line, chasing after each other during the day and bugling all night long, the bears and bison are chowing down on anything they can find to get nice and fat for the winter, and the wolves are reveling in the cooler weather that they love.
Sometimes the activity on the ground is eclipsed by the activity in the sky; thunderclouds climb into the stratosphere, the wind whips into a frenzy, and everyone takes shelter from the driving hail and rain. The setting sun turns the clouds an eerie fire-red, and the rain sets in with a vengeance, turning the rivers to mud and the creeks to rushing torrents. By morning it’s all finished, and the sun scours away the clouds that hang in the valleys.
