From the Earth upwards is about 10 miles to the stratosphere, and short wave blue light tends to scatter giving our sky its bluish tint during the day. In the late afternoon, it is about 20 miles to the horizon plus the same 10 miles to the stratosphere. Only the long wave red light can penetrate this larger distance, so sunsets are oranges and reds, such as here giving these snowy branches an ironic "fiery" cast.
Strokkur , Iceland... a part of the Golden Circle... The most magical photograph I have seen of this spouting geothermal area, with the crystal clear waters revealing the amazing beauty just under the Earth's skin. Getting to see this natural wonder would be pretty miraculous, it's not often you get the opportunity to look inside our planet and see that it's beautiful inside and out!
