All man-made structures of the park have crumbled into nothing but rubble.
1,000 years after people
Due to lack of humans causing climate changes to earth, this place now has more forests and grasslands, and without human settlements, animals aren't struggling from food shortages, so animals like giant bison (larger long-horned descendants of a group of plains bison) have evolved.
1,000,000 years after people
The supervolcano of this park has erupted, but fortunately for most animals in the area, the effects are minimal, unlike in prehistoric times, where the Yellowstone's volcano had erupted so much that it killed off previous species, this volcano has finally ran out of fuel and the volcano has died, leaving many animals in Yellowstone National Park safe.
2,000,000 years after people
Many future sapient beings including sapient dylanuses, European vampires, Collinwood vampires, American vampires, Bass.EXEs, Robot Masters, Maverick Hunters, Net-Navis, FM-Ians, and many others have discovered many remanence of what was once Yellowstone National Park and discovered many animals around them including several species of bison (plains bison, giant bison, etc), elk, whitetail deer, brown/grizzly bears, black bears, gray wolves, and other natives that still exist in this region, in fact, most of North America. They've also discovered formerly nonnative species like large aurochs-like descendants of feral cattle, small agile deer-like cattle descendants, aggressive vampire-like fully-carnivorous descendants of the American killer dylanuses, as well as marthanuses, American elephants, North American tapirs, North American baboons, North American dromedary camels, and among others.
