Breakthrough beyond Ink Sump

The boulder choke in the roof of Doom’s Retreat Aven beyond Ink Sump in Peak Cavern has been breached and a way on found into a large chamber beyond, “Endeavour”. There is a further climb, passage and chamber above Endeavour. For the moment the team is concentrating on consolidation work, mainly strengthening and enlarging the shaft from Doom’s Retreat to Endeavour. Radio location has shown that the surveyed location of Doom’s Retreat is accurate with reference to the surface but it has not so far been possible to measure the depth of the chamber from the surface.

This is a significant breakthrough after many years of work on the other side of a 200m dive, and it seems that the logistics of supply have been daunting. Congratulations to everyone involved.
