Fascinating paper and gallery here of Florida Harvester Ant ant hills that have been flooded with orthodontal plaster, and then the earth removed from around them. To the right:
A plaster cast of a large Pogonomyrmex badius nest. This nest consisted of 135 chambers and 12 meters of vertical shafts. The top-heavy distribution of chamber area and spacing is typical for the species, as are the helical shafts and the decrease of chamber size with depth
Beautiful.
