Dr. Chris Moore of University of Indianapolis brought out a bucket auger to drill into the ground and extract layers of soil to see what this anomaly is made of.
Moore sifted through the dirt in each layer, noting its composition and whether or not it contained any artifacts. A student recorded his observations so we have a record of the layers of soil.
Pay dirt! 85 cm below the surface, we hit a cultural layer containing tile (orange-colored piece), charcoal and coal (larger black pieces). Such materials were commonly used as backfill years ago when someone dug up an area and then filled it back in. The question is, why was someone digging here? Could it be John's grave?
Who's up for another History Beneath Us program focusing on this area?
