The east face, photographed in 2009 on the only camera anyone had. It is reproduced at the size that camera can honestly hold.
QuarryThe survey
Survey plate, east face
Not recovered
A single hand-drawn plate carried the whole survey: eleven benches, their heights, and the fault the drilling had to avoid. It is not withheld, it is gone - the office it lived in closed in 2011 and no copy was kept. What is recorded here is what two people who used it independently remember of it, which is why the block is marked interpretive.
