From IFLScience.com:
There are plenty of things that make Yellowstone National Park special. It’s the US’s oldest National Park, dating back more than 150 years. It’s dotted by hot springs that are both fantastically vibrant and existentially (and immediately) perilous. It’s the only place in the country where you could, at least theoretically, get away with murder.
But equally striking is the flourishing wildlife. Flora and fauna abound, harkening back to an America not yet touched by colonialist hands: bison roam wild (indeed, sometimes they’re positively livid); grizzly bears are born and live in safety; cougars are… well, the cougars aren’t doing too hot, to be honest, but they’re trying their best.
And, at the very apex of the local food chain, there are the wolves.
