02/27/2016: Brett Hemphill and I went to the end of exploration in The Not Dead Yet Room. I tied in and ran the reel while Brett scouted ahead. The cave quickly dropped to 400' with an average depth of 360' We laid 600' of line and connected the newly discovered Sirion Tunnel to the EOL at the White Room discovered by the 2007 team. Once here we tied in and explored another 400' of passage that ended in a wide flat room. Total dive time was just over 16 hrs.
