From Y Llethr a view to the South along the ridge of Crib-y-rhiw with the distinctive Syncline on Diffwys (750m) in the distance.
Y Llethr is the highest mountain in the Rhinogydd range , the summit consists of a flat grassy top marked only by a small cairn.
The Syncline is an impressive Fold - an exposure of the Caerdeon Syncline which plunges southward with the younger strata
towards the Mawddach estuary.
