Taken 7th September 2002: This is the (rather sinister) Nant-y-Moch Dam. If you own the latest version of the Landranger map for the area (135) you can take a closer look, because it’s on the front cover. The red arrow indicates where the cairn is now sited, but it was originally just ‘off-shore’ of the promontory where it has been reconstructed (in the direction of the dam).
