More MRO rigging at the 20' pitch. The idea from last week didn't work as well as we had hoped so we set about revising the plan. We put a Tyroleon traverse horizontally across the roof of the passage which then gave us sufficient height to transfer the stretcher horizontally and well away from the water. <br> <br>Whilst rigging the tyroleon we also climbed up into Easter Grotto which is a very infrequently visited but rather pretty chamber in the roof of the passage above the 20' pitch. To get into the chamber is a tight and akward squeeze which proved entertaining in reverse whilst trying not to fall out the roof.
