Underground History: LIDAR And Lightning At Burial Mounds


You think of archaeology, you think of shovels... digging in the ground is what recovers artifacts. 

But technology helps in covering broader areas, like the ancient burial mounds of the Prairie Island Indian Community in Minnesota.  Most of the mounds have been disturbed, but LIDAR technology has allowed the mapping of the remaining mounds. 

And further investigation shows a propensity for lightning strikes at the mounds.  That's the focus of this month's "Underground History" with Mark Tveskov of the Southern Oregon University Laboratory of Anthropology.  He joins us with mound investigators Sigrid Arnott and David Maki.
