The Mogollon Monster, also known as the Arizona Bigfoot, is an ape-like creature, similar to descriptions of Bigfoot, The Mogollon Monster is commonly described as a large bipedal creature, over 7 feet (2 m) tall with large, red eyes.

The majority of Mogollon Monster sightings are said to occur in the Ponderosa pine forests of the Mogollon Rim with reported sightings range along Arizona's Mogollon Rim, from Prescott north to Williams, southeast to Alpine, south to Clifton, and northwest back to Prescott.

Professor emeritus of biology, Stan Lindstedt, of Northern Arizona University, dismisses the idea that a large humanoid creature would remain hidden in such a large area of the country. "I put that in the category of mythology that can certainly make our culture interesting, but has nothing to do with science."
