The 17th entrance into the 4 Valleys System opened up yesterday. This is another entrance into Fridge Door Cave #1800, allowing much easier access for divers to push north in sump 3. Previously identified using subphones, the new hole (site 5000) was dug out from zero to over 71km in a couple of hours.
