18 Oct 2007 From: John Barnard Clogwyn Llech Lefn (Bwlch Tri Marchog Top) Recently there was a message posted asking if anyone had surveyed this hill as a potential for the Nuttalls'list. Myrddyn Phillips and I surveyed it today with a Leica Automatic Level and Staff. The ascent from Bwlch to Summit was measured to be 14.0+/-0.1m. The closing error on the up and down survey was 2mm so we are confident of this result. Therefore, not a qualifier!
