This is another from the Guardian’s Eyewitness series, and it’s also another in a developing Frames of Reference series. This is Cwm Idwal, a valley in Snowdonia, and a word which seems to keep recurring, either as cwm or combe or comb. See earlier posts Down & Round & Up & Over and Wind Comb and Combe Again. This time it’s a photograph which won the National Parks Landscape Photograph Competition by Michal Tekel and it’s what you might call sublime.
