Third in a series of videos from our summer 2019 family road trip that covered 11 states in 4,400 miles in nine days. It was my first return to Yellowstone National Park in 40 years. Old Faithful, the other geysers, the geothermal vents, and the wildlife were just as impressive. We even managed to find the scene of one of my favorite 1942 Ansel Adams photos near the Grand Tetons.
