Elk

Bizarre Elk skeleton in the Gore Range. Oct 2018

It appeared to be completely natural. I found the legs nearby.

Mountain Goat

Black Bear

Bobcaft

An earlier version of this page listed this as a Mountain Lion.  I've seen a number of them since (always at night) and I'm quite sure it's Bobcat and not a Mountain Lion.  There's no obvious long, powerful tail and he/she appears to be fairly small.  There are no spots and the ears appear rounded, but the real tell is the eyes.  Bobcats tend to have a white perimeter (as in the picture below) and mountain lions have a very dark perimeter.
