The Ordnance Survey 25K map (Explorer 165 'Swansea and Gower') appears to suggest that Mynydd y Betws is the expanse of moorland which culminates at SN 662107 at a height of 341m in Carmarthenshire. The mountain of Mynydd y Gwair to its south appears to culminate at the summit of Penlle'rcastell at around SN 664094 at a height of 371m, within the county borough of Swansea, making this the highest piece of ground between the Loughor and the Tawe, south of the Black Mountain. This runs contrary to what the article currently states. See also page on Mynydd y Gwair. Anyone anything to contribute on this matter? Geopersona (talk) 07:07, 2 October 2010 (UTC)Reply
