 <p>Each wallet contains the scanned original in-cave survey notes and sketches of 
 plans and elevations. It also contains scans of centre-line survex output on which
 hand-drawn passage sections are drawn. These hand-drawn passages will eventually be 
 traced to produce Tunnel or Therion drawings and eventually the final complete cave survey.
