16th December 2012. While out walking the dog in Stockhill Woods came across small rift [~1.0m L x ~0.4m W x ~1.0m depth] with small stream, some evidence of greater water flow recently.
Located in small depression at north end of a group of larger depressions. Appears to be in limestone shale. Considered to have seen the attention of miners in the past.
Following discussions with others it is likely that the site has been previously noted.
