Though Yellowstone National Park is mainly known for Old Faithful and its other thermal features, and for wildlife, mainly the American Bison and Wolves (and maybe Grizzly Bears), the Grand Canyon of the Yellowstone and Yellowstone Falls are also major attractions. This is Lower Falls, from the Lower Falls overlook and Inspiration Point and the canyon in that area. The Yellowstone River has been cutting the canyon for 100s of thousands of years through the thermally weakened rhyolite left over from the formation and infilling of the caldera. The falls themselves, Upper Falls at 109 feet and lower at 308 feet, are there because the rock at their lips is just a bit harder than the rhyolite of the canyon. Except for the close-up of the falls, which was taken with the Sony a6700 and Tamron 50-400 at 126mm equivalent, the other shots are from 15 to 27mm as needed for framing with the Sony a5100 using Superior Auto with Landscape Scene Mode selected.
