The thing about Yellowstone is......
Yes, it's vast and there are many remote areas. But there are also millions of tourists. EVERYWHERE. It's also a land of a billion photos. Last time I was there (late October), bus loads of Chinese tourists were pulling up as if from nowhere, geysers and mud pools all around. They'd all clamber out, stand at the foot of the bus steps and snap photos with long lenses. They didn't even step more than a few feet from the bus! Not even onto the boardwalk or to peer over the rail. I was quite shocked: evidently the prize was a "been there, done that" photo and not the experience. At any rate, yep, billions of photos out there via long lenses.
If you're having to remove a body, you'd certainly be in a place where someone could see you. You'd be parked at a busy pullover. And we might be talking about as much as 140 lbs of dead weight body. Otherwise, you'd have to dismember the body in order to lift.... I'm creeping myself out.
Backcountry assault and burial? No way CD and LV are heading into the woods with grizzlies and wolves: they're totally NOT the type! Doubt they'd even set foot on a woodland trail. Their thing is evidently lalalala on a Hawaii beach in the sunset holding hands...
I could totally see them buying and taking a silver and orange space blanket to Yellowstone just in case, though...
BTW, I've never seen a grizzly or a wolf at Yellowstone, but I'm quite convinced the mere thought would deter LV and CD.
