During the last few centuries large primates of up to eight feet tall have been spotted across the United States. Although Big Foot, as the beast has become known, has been sighted in every state, sightings are concentrated in the remote mountainous parts of the country.

In October 1958 a group of loggers came across several human-like footprints in a remote part of the Northern Californian woods. The footprints ranged in length from 12 to 17 inches long and about 7 inches wide. Big Foot was spotted by several other road construction workers as they hacked a ribbon of civilisation further into the dense bush. Since then the animal that the Indians call Sasquatch has fascinated adventurers. For three weeks last August a team of experts went into the remote Siskiyou Mountains in Northern California looking for some answers. Secretary of the International Society of Cryptozoology, Richard Greenwell, his son Darwin, Primatologist Jeffrey Meldrum and their mountain guide Mark Slack found no proof of the existence of Big Foot. But their experiences added up to a strong case in favour of the creatureís presence. The group found several sets of human-like tracks, measuring up to 16 inches in length. They heard howls and their camp was visited by animals that they couldnít explain away as bears. Animal X obtained exclusive material from the teamís expedition into the wilderness. Richard Greenwell suggests Big Foot may be related to the Gigantopithecus that roamed China 300,000 years ago. He suggests that it may have crossed the Bering land bridge from Asia and into North America and remained in the forests, leading a largely reclusive life.
