Deer mutilation in Yellowstone?!

Was a perfectly severed deer head found on isolated trail in Yellowstone?

From ranker.com: "I'm a ranger at Yellowstone. Couple weeks ago I was exploring the Lamar Valley, about 11 miles from the nearest road and even further to the park boundary.

There, in the middle of the trail, is a perfectly severed deer head. No blood, no raggedness at the severance. Perfectly in tact.

This is weird because I have seen wolf and bear kills, and I used to find cougar kills in SD with radio tracking just after the cougar made them.

This was not any of those things. The head was completely uneaten - eyes, tongue, everything intact. Even the ravens hadn't touched it yet. No caching, no scat. Right smack in the trail, but again, no blood.

Even a human doing it made no conventional sense. It was a doe so it had no antlers, plus, why leave it in the trail?

Whole thing, even in broad daylight, gave me chills. Just an ocean of waving grass, bison calmly grazing, and a perfectly clean deer head right on the path."
