Mapping Mountains – Hill Reclassifications – Y Pedwarau

Y Garn (SH 758 375) - 400m Sub-Pedwar reclassified to Pedwar

There has been a reclassification of a 400m Sub-Pedwar to a Pedwar through surveying with the Trimble GeoXH 6000.  The hill has a convoluted history of appearing (or not appearing in some cases) in the 400m hills of Wales P30 list.  The survey with the Trimble GeoXH 6000 has now determined that the hill has over 30m of prominence and should be included in the Y Pedwarau.  The hill is named Y Garn (SH 758 375) and is situated in the Arenig mountains to the west of Llyn Tryweryn (SH 788 385).

The hill will be added to the Y Pedwarau list in the 2^nd edition that will hopefully be published by Europeaklist.  The list of Pedwar hills is also available from the Haroldstreet website.
