Our Underground Rescue Leader was contacted by Teesdale and Weardale Mountain Rescue Team and asked to assist with the search for 3 overdue cavers. They had entered an Old mine system in Teesdale intending to travel through the system. However, a friend reported them overdue and a search and rescue response was activated by Teesdale, with support from Cumbria Ore Mines Rescue Unit and ourselves. It would appear that the exit sum had become submerged and the ropes used to enter the mine via some deep shafts removed. A small team were able to reduce the water level on the exit and enter the cave, where they then located the party and brought them out safely.
