Climbs.—The north face of this mountain is remarkably fine and contains all the climbing there is. At the east end is the bristly ridge leading down to Bwlch Tryfaen. This is stimulating, but not difficult. In the centre of the face there is a large gully, ascended in November 1894 by J. M. A. T., H. H., and H. E. They did not find it necessary to use the rope. The lofty pitch at the foot of the eastern gully is decidedly hard. (J. M. A. T.) In May 1888 W. E. C., A. E., E. B., and E. K. found and ascended a gully close under the west side of Castell Gwynt, and add that they reached Penygwrhyd by way of Cwm Graianog. The last statement is very mysterious. About the Castell itself (the rugged pile of rocks between the two Glyders, marked by its slender outstanding 'sentinel'), and about the summit of the Fach, there are some good scrambles on a small scale.

Directly under the top stone is the minimum thermometer, which has been kept there for some years.[ [10] ] The most interesting thing on the whole mountain is undoubtedly the pile of stones on the top. According to the bard Taliesin it is the burial-place of a mighty warrior, one Ebediw. If a kind of Stonehenge was erected there to his memory and afterwards got upset by an earthquake it might account for present appearances. Edward Lhwyd, the great antiquary, was particularly struck by them 200 years ago, and his description and remarks are equally applicable to-day.

'On the utmost top of the Glyder,' he says, 'I observed prodigious heaps of stones, many of them of the largeness of those of Stonehenge, but of all the irregular shapes imaginable, and all lying in such confusion as the ruins of any building can be supposed to do.... Had they been in a valley I had concluded they had fallen from the neighbouring rocks ... but, being on the highest part of the hill, they seemed to me much more remarkable.' He goes on to remark upon a precipice which has not been identified (see Esgair Felen). 'On the west side of the same hill there is, amongst many others, one naked precipice (near or one of the Trigfylchau, but distinguished by no particular name), as steep as any I have seen, but so adorned with numerous equidistant pillars, and these again slightly crossed at certain joints. 'Twas evident that the gullies or interstices were occasioned by a continued dropping of water down this cliff.' Trigfylchau, by the way (i.e. 'Twisting Gaps'), is a name which does not seem to be known at the present day.

Lhwyd's description fired the curiosity of the travellers who explored Wales nearly a century later, and the amusing part of it is that they could not find this wonderful mountain, or even hear of it from the intelligent natives.

Cradock (1770) found an aged man, who told him that the mountain was 'now called the Wythwar (Wyddfa),' which stands 'a few miles south of the parish of Clynog;' and H. P. Wyndham went further by identifying it with 'the mountain called Ryvil in Speed's map' (i.e. Yr Eifl). It shows how little the natives knew about their mountains until the travellers came and taught them. Pennant made the ascent, and gives a picture of the summit. Bingley also went up, and gives a good description.

Kingsley's fine description, in Two Years Ago, of Elsley's ascent really applies mainly to Glyder Fach, though he only mentions the Fawr. Elsley's descent, by the way, was apparently into Bochllwyd by way of Castell Gwynt.
