Named after the nearby "spring" used as a water supply
   A small complex of rifts and tubes with one entrance having a rickety grille. A rift to the left of the southwest entrance was dug out beyond 2 blocks and explored in July 2023. This passage is a mixture of crawling, squeezing and walking and ends where the passage becomes too small after squeeze into a small chamber.
   A dig was also carried out straight ahead at the same entrance; this was finished when large blocks in the floor were encountered and the passage became smaller.
