Mountains in the distance take on a bluish hue. Blafell (the blue mountain) guards southern approaches to the Kjolur region of central Iceland. It's an old tuff mountain formed during an eruption beneath a glacier and reaches a height of 3,950 ft. In face, Blafell gives us a good indication of glaciers during the period of its formation. It's the highest peak (apart from glaciers) in southwestern Iceland.

Blafell had a famous resident - Bergthor the troll, who possessed second sight along with many other talents and had a good relationship with humans as long as they didn't bother him. One day, Bergthor became thirsty on his way from town back to his cave. He was close to Bergstadur farm and asked the lady of the house for some water. While the lady was fetching his water Bergthor tapped a nearby rock, forming a tub-shaped depression in it, for which the farm is now famous. Tubs were used for storing whey. It was said that any whey in Bergthor's tub would never freeze or become used up - and indeed, as far as anyone knows, it never has.
