I’ve heard that Iceland is green and Greenland is icy, and from what we saw, that is a pretty true statement.

We didn’t actually see ice until the end of our third day in Iceland, when we started to get views of the glaciers.
We visited the Jökulsárlón Glacier Lagoon. We took a Zodiak boat tour into the lagoon and cruised around icebergs and the edge of the glacier.
We were lucky enough to see the glacier calve (which they says happens about once a day) and splash into the water.
It makes quite a sound, which stuns the fish, and serves as a dinner bell for birds and seals to come around for a fish buffet.
What we could see of the glaciers is actually only 10% of their total size.
Much of the glacier and some of the icebergs have black lines in them, which are ash deposits from volcanic eruptions over time.
Our guide told us that his grandfather said that the trolls put magic into the ice to make it blue to attract humans so they can eat them.
The lagoon opens up into the ocean at Diamond a Beach, which gets its name from the large pieces of ice that float from the glacier and litter the black sand beach.
Next up: waterfalls!
