Þórufoss¹ is a pretty waterfall in Laxá í Kjós river in western #Iceland.
Its 16m (52.4ft) drop is a wide horsetail into a steep-sided ravine. The area lies between Þingvallavatn² lake and Hvalfjörður³ fjord.
When we first visited in 2014 it was fairly obscure, but it's very popular now.
In summer or winter it's well worth a visit.

Back to summertime, and this colour photo shows the ravine through which the river flows, downstream from the waterfall. Tall hills are surrounding the canyon on the far side, which are covered in grass and scree. The top of another waterfall is just visible further along the gulley.

A detail of one side of the icicles, showing that some water is still flowing. The ice structures are impressive and quite solid.

Another shot of the same waterfall, this time in winter. The face of the falls is now frozen almost solid, large icicles have formed and are covered with a dusting of snow. The river approaching the crest is surfaced with ice which has been hidden beneath a layer of snow, dark rock is still visible but is heavily iced.

A colour photo of a pretty waterfall dropping between rocky walls and green grasses. The sunlight from above is catching the almost straight crest and highlighting it. The river approaching the drop is quite flat and calm, and the base of the cascade is white foam in the turquoise water.
