MANISTIQUE, Mich. — Researchers will visit the Upper Peninsula next month to search for evidence of the legendary creature known as "Bigfoot" or "Sasquatch."

The expedition will focus on eastern Marquette County, said Matthew Moneymaker of the Bigfoot Field Researchers Organization.

"We'll be looking for evidence supporting a presence. ... We hope to meet local people who might have seen a Sasquatch or heard of someone else who had an encounter," Moneymaker told the Daily Press of Escanaba.

The legend of Bigfoot dates back centuries. But skeptics have challenged accounts of sightings, and practical jokers have staged hoaxes that have included grainy film footage of people dressed in costumes.

But Moneymaker said members of his organization have either glimpsed Bigfoot or gotten close enough to hear the creature in all but three of 30 expeditions in the United States and Canada.

Dr. Grover Krantz, a scientist specializing in cryptozoology, the study of creatures that have not been proven to exist, believes Bigfoot is a "gigantopithecus," a branch of primitive man believed to have existed 3 million years ago.
