A tour guide and former park ranger last weekend had what he called a "phenomenal" encounter with one of Yellowstone National Park's rarest and most elusive animals: a wolverine.
He even snapped a picture to prove it.
MacNeil Lyons, owner of Yellowstone Insight, was with a tour group in the park’s northern reaches March 5 when the visitors spotted what he calls a "unicorn."
The wolverine — the largest species in the mustelid, or weasel, family — is related to otters, ferrets and minks.
In North America, the wolverine's southernmost range touches Yellowstone National Park, according to the National Wildlife Federation.
