# Freeze-Falls

January 9, 2015

It’s turned cold this week in a lot of places, and one of those places is Iceland. You can guess from the name that this island is pretty darn cold a lot of the time, since it lies far north at the edge of the Arctic Ocean. But that hasn’t stopped people from visiting the awesome Godafoss Waterfall to take pictures of it. The name means “waterfall of the gods,” and you need almost god-like powers to get there: you have to make a tough drive through the mountains, and then stand in subzero windy weather to photograph the falls. The bigger problem is that the falling water sprays everywhere in the strong wind, coating the camera lens with ice and forcing the photographer to wipe it off over and over. But as you see from these amazing pictures of icicles, spray and sky, the work is worth it.

Wee ones: Which is colder, a mountain where it’s 14 degrees or one where it’s 12 degrees?

Little kids: If you take 5 hours to fly to Iceland and 4 hours to drive to the falls, how long does it take you to get there?  Bonus: If you then take 3 hours to snap pictures and then take the same drive and flight home, how long does the whole trip take to get those photos?

Big kids: The waterfalls are about 32 feet high. If you hang from a helicopter 43 feet above that to take pictures, how high above the ground are you?  Bonus: Just as we can use inches or centimeters for distance, we can measure temperature in Celsius or Fahrenheit. The Fahrenheit number is 9/5 of the Celsius number plus 32. One photographer faced negative 15 degrees C weather…what is that in Fahrenheit?
