A discovery tour with rogerw3 ('there can't just be one there') and as you approach the public area all six can be easily sighted. So, why, on a previous visit to log the original listed trig were these overlooked by the 'mushroom? No idea except it was wet and windy back in 2013.

M6 stands on the lower slope of the hillside, and can be easily viewed at the end of the dam wall walkway.
