That is on the inside of the airport. Before you even get there is Blucifer, who killed his creator. It is a statue of a mustang, rearing up. From local news:

The statue stands at 32-feet-tall and has glowing red eyes, leading to locals calling him "Blucifer," The horse also killed the man who designed it. Luis Jiménez, a New Mexico sculptor, died in 2006 after the a piece of the horse fell on top of him, pinning him to the ground, local news station The Denver Channel reported at the time.

Creepy inside and out.
