An excursion from Reykjavik in Iceland.

The main photo shows a hot spring & small geyser emitting steam. The 1st extra, is of a resulting stream & a warning that the temperature of the water can be at, or close to boiling point. When the photo of the waterfall was taken, the air temperature was about -20c, with the wind  blowing virtually horizontally as can be seen in the car park picture. Finally , at another viewing point later in the day, the weather was sunny but still remained very cold.
