Description
Comprises to two separate natural features which have been mined in the past. Sunday Mine (Passage) is a fairly straight, wide natural passage. Accessed by Aaron's Entrance about 5 metres above the road on the north side of the Dale just east of the 50MPH sign. It leads past a mined level with unstable deads to a u-bend into a tall rift.

A slot in the floor then leads along a smaller continuation of the passage to a small chamber. There is voice connection here to Sunday Mine (Rift). There also used to be a shaft to the surface, but this collapsed years earlier.

Sunday Mine (Rift) was accessed by 4 oil drums just uphill from the same 50MPH sign. The drums rotted and fill blocked the passage some 25-30 years ago. Members of Chesterfield Caving Club dug a new entrance closer to the hillside, reopening the rift in January 2012.

The rift is about 25m long, 2m wide and up to 10 m high. There is a sump near to the end some 3 or 4m lower than the main rift floor. Just before this is the voice connection to the other passage.

Access
Open access, no permission required.
