Derlwyn (SH 588 586) - 400m Sub-Pedwar addition 

There has been an addition to the 400m Sub-Pedwar category through surveying with the Trimble GeoXH 6000.  The hill is named Derlwyn (SH 588 586) and it is situated on the Llanberis ridge of Yr Wyddfa.  The summit area is crowned by small outcrops of rock and has fine views southward towards Crib y Ddysgl and Yr Wyddfa and eastward toward the high peaks of the Glyderau.

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.
