Suspected tunnel across the C and D rows

Between 2020 and 2021 the drilling grid kept bringing up sawn and hewn tunnel timber at the same level: B-4, BC-4, C-4.5, C-5, CD-2.5, D-2 and DE-1.5 all recorded tunnel wood or collapsed tunnel between 79 and 94 ft, with about 20 ft of buckled beams in DE-1.5. The line joins those holes in order; it shows where a tunnel was hit, not its course between holes. Which searcher dug it has not been established.

The record gives points, not the course between them.
