The Glyderau (a Welsh plural form, also known in English as the Glyders) are a mountain group in Snowdonia, North Wales. The name derives from the highest peaks in the range, Glyder Fawr and Glyder Fach. According to Sir Ifor Williams, the word "Glyder" derives from the Welsh word "Cludair", meaning a heap of stones.

I then swapped and led the descent down - took three descent lines including a down climb from a direct belay - a traverse again using a direct belay, and then a lower in turn (one at a time) in to the main gully and a walk around to milestone buttress.
