NASA’s laser remote-sensing Lidar technology used to uncover History

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – Some 10,500 years ago, hunters gathered each year near the Beaver River in what is now western Oklahoma. There, they funneled bison into narrow, dead-end arroyos — steep gullies cut into the hillside by the river — where they killed them en masse, sliced off the choicest meat and left behind piles of skeletons.

Walk through western Oklahoma today and there is little visible evidence of that ancient landscape, much less the hunting expeditions it hosted. Few bison remain, and dirt and rocks have filled in many of the arroyos.

An archaeological team led by University of Oklahoma’s Lee Bement excavates a 10,500-year-old bison kill site near the Beaver River. Using lidar scanning, the team was able to narrow down sites to search further for prehistoric artifacts. (Lee Bement)
