Yellowstone… simply magic. I start with 5 shots from our condo balcony. Then on to Yellowstone. The Madison River, Norris Basin, the Grand Canyon of Yellowstone and Yellowstone Falls. Stunning! Next, Yellowstone Lake. Yellowstone Lake is the largest body of water in Wyoming and largest in Yellowstone National Park, covering 136 square miles. It is roughly 20 miles long, 14 miles wide, with an average depth of 139 feet and a maximum of 394 feet. Finally, a few Bison on the drive home.
