These mountains hold creatures you won’t see anywhere else and they’re living their best hidden lives.

The Rocky Mountains feel like a completely different planet when it comes to wildlife. Some of the residents look like they were created by a daydreaming artist who went a little wild with the imagination brush. Others have evolved in ways that make them perfectly suited to the thin air, unpredictable weather, and rugged terrain. These aren’t your everyday backyard squirrels or pigeons. These are the animals that make you stop mid-hike and question if you just stepped into a nature documentary.
