Cliff Barackman, who has been on the trail of the mythical beast for 20 years, recovered giant footprints from an abandoned mattress in the US wilderness.

Photos show the barefooted prints, measuring an enormous 13 inches long by five-and-a-half inches wide, impressed upon the fabric in mud.

And the distance between one footprint and another, heel to heel, was a monstrous 48 inches - suggesting a truly giant gait.

Mr Barackman, 47, said the prints were found in Alderwood State Wayside Park, Oregon - a place where Bigfoot sightings are common.

Only 13" long by 5.5" wide? That's a juvenile, probably about 6 to 6.5 feet tall. The footprints of the big mature silverbacks can hit 20" by 8.5". Those boogers can run 10' plus. ;-)  To read more, click here.
