Some residents of the Umatilla Indian Reservation in Oregon believe the mysterious cries coming from a nearby swamp are being made by Bigfoot.
One of the officials on the reservation said the cries were first reported last month and there are many theories as to what animals are making the sounds.
Another official said that Bigfoot is part of the tribal tradition and spiritual beliefs, while others claim that it may be the cougars who are in their breeding season.
