The dead mountain lion and bighorn sheep were found on a closed road in Glacier National Park. Both evidently fell from somewhere very high on the cliffs above and to the right during the struggle which took place when the lion attacked the ram. The dead lion’s mouth can be seen to contain a large clump of the ram’s hair.
The Imgur commentator confused the bighorn sheep (Ovis canadensis) with a mountain goat (Oreamnos americanus)
Facebook commentators were quoting Tolkein: “Until at last, I threw down my enemy and smote his ruin upon the mountainside.”
