22 Sep 2008 From: Eric Povall Mynedd Graig Goch Whilst it is now accepted as a 610m + mountain does it satisfy the Nuttall criteria as a mountain? Looking closely at the Explorer OL17 map there is another spot height at 606m about 240m southeast of the top. Between the two spot heights is a narrow valley, just below the 600m contour line. Unless this narrow area is at 595m or less then there is not a 15m drop all round and thus not a Nuttall mountain as defined by John and Anne in their introduction to Vol 1 Wales . Interesting.
