Myself and other members of the Cleveland Mining Heritage Society also cleared the location of the early Cookes ventilator where we removed undergrowth from the masonery.
As a reward for helping out, we were allowed to look into the drift which is not open to the public.Inside is a hole in the wall which was opened when the museum was first developed, this leads over a flooded shaft. This would have been blocked then ventilation moved to other machinery.
A second short shaft also goes upwards, into the back of the mine recreation part of the museum.
There also a small bypass tunnel, to get you past the machinery when it was in use.
