Sunset through the Machair, from Traigh Seilebost looking towards Taransay Island. An idyllic scene. Machair means in Scotland, especially the Western Isles, low-lying arable or grazing land formed near the coast by the deposition of sand and shell fragments by the wind. A fine habitat for many birds and wild flowers as well as being stunningly beautiful. The Isle of Harris, Outer Hebrides or Western Isles, Scotland.
