English: Layers of Footprints |

Description |
English: Aerial image of fossilized human footprints in the gypsum sand. Trenches are useful to researchers in revealing multiple levels around the same area. Fossilized human footprints have been found at various sedimentary levels as depicted in the image. These suggest that human activity has occured over a longer time period, as opposed to an isolated event.
