Thankyou for your observation Desainme,i always get that wrong on the Sp and im a Cartographer!!!
Please negate the longitude to keep this mountain out of the north sea. All stuff less than 180 degrees west of London has negative longitude.
Aran is not second highest outside snowdon area- cadair idris is smaller ! (common mistake). also bwlch y groes is the second highest road.. gospel pass in south wales is 4 metres higher!
also mid wales? no, north wales. pumlumon is mid wales.
