The tracks were confined to two layers of sediment, vertically separated by 15 feet and about 10,000 years. The upper layer contained three footprint trails, two of two prints each and one of seven prints, as well as several isolated prints. The lower layer preserved one trail of two prints and a single isolated print.Homo Erectus walks and runs across huge continents for a million years. About a dozen footprints survive.
