Rumbling Hole is one of the many fenced-off sinkholes near the road on Leck Fell in Lancashire. The entrance shaft is approximately 160 feet deep and often has a small waterfall cascading down the side opposite the three trees that grow at the edge of the vertical shaft, one of which provides a convenient belay point for the entrance pitch.[1]
Exploration
A connection was made between Rumbling Hole and Lost John's Cave by Lancaster University Speleological Society in 1985.[2] It is a part of the Three Counties System, a network of connected caves beneath Westmorland, Lancashire and Yorkshire.
During a visit to Rumbling Beck Cave (a short horizontal cave that sinks 100 feet from the main sinkhole and discharges its stream into the main shaft) in late 2007, the Misty Mountain Mud Miners noticed an unexplored hole in the side of the shaft and, over six trips, pushed a new route 1,150 feet long, named the Dead Bobbin Series, down to 390 feet below surface level,[3] installing £160 worth of fixed bolts.[4]
