As with the nearby cementstone mine at Kettleness, these are also positioned at the top of a quarry just below the sandstone cap, making for a pretty tricky scramble.
Three adjacent entrances can be found, all appear to have suffered collapses from the loose shale roof so exploration isn’t the best idea.
The leftmost tunnel slopes steeply downwards, i’m unsure if they were built dug this way or whether its just successive heaped up roof collapses leading down to the level of the original drift.
Access to the central tunnel is tighter, although a similar flat area at the bottom of the slope could be seen when I stuck the camera over the top.
The rightmost entrance has totally collapsed and only a small gap is left.
Another entrance is visible high on a ledge to the north, but access to that looks to be virtually impossible without climbing gear.
