Iceland - Waterfalls

If you're a reader of this blog then you already know that my wife and I recently visited Iceland for a kid-less vacation.  It doesn't take long to discover that Iceland has many waterfalls.  Driving along the ring road (Highway 1), it's easy to see many waterfalls in the hills/mountains.  Several of the waterfalls are accessible without much walking, and many more are accessible if you're willing to walk a few km.  Here are some of the pictures we took.

So what causes a waterfall?  Two things are needed.  1.  A water supply.  2.  A distinct change in land elevation.  In Iceland the water supply comes from the glaciers and the often rainy climate.  The distinct change in land elevation comes from the fact that Iceland is a volcano, much like the islands of Hawaii (which also have many waterfalls.  Water will flow from a higher elevation to a lower elevation, down to sea level.  When water cross a sharp drop in elevation, a waterfall is produced.  

Waterfalls are a thing of beauty and there was no shortage of beauty in Iceland!
