The lake is famous for fly fishing, and for the storms that make for difficult navigation. The carboniferous limestone that underlies much of the central lowlands of Ireland is exposed at Lough Corrib and Lough Mask in Galway and Mayo.
Both lakes are 'solution hollows', where water has gradually eroded into the limestone to form large depressions in which the lakes then form. The erosion can be seen on a smaller scale in these rocks in the foreground.
Having spent the day travelling around this scenic part of Galway, I set up at the lake shore to take some sunset images and videos.
This Blue Hour (l'Heure Bleue) is another name for Twilight, the period just before dawn and just after sunset when there is neither daylight nor darkness. The Sun is still below the horizon but the upper atmosphere is still illuminated and in turn light scatters towards the surface of the Earth.
