Almannagjá Ravine

Politically, Iceland is considered part of Europe. Geologically, though, it is a very different situation. Iceland sits atop the mid-Atlantic ridge. The ridge is a chain of volcanic mountains, mostly under the Atlantic Ocean that stretches most of the way between the North and South Poles. It is the dividing line between the Eurasian and North American tectonic plates. As the volcanos erupt, the lava causes the Atlantic Ocean to become wider, pushing North and South America westward and Europe and Africa eastward.
The Almannagjá Ravine is a crack or rift between the North American and Eurasian plates that is located in Þingvellir National Park It is a small part of the section of the mid-Atlantic ridge that runs northeast to southwest through Iceland. It geologically, marks the boundary between Europe and North America.
These images were taken in the Almannagjá Ravine. As you look at them, the walls to the left are in Europe and those on the right are in North America. For geology geeks like my wife and I, it is truly amazing to be able to stand on the mid-Atlantic ridge and to be able to walk between Europe and North America.
In 930, Iceland established its parliament in Þingvellir, near this location. Sessions were held there until 1800.

I hope you enjoy these images.

Icebergs, Auroras and Birds

I am mashing together 2 different subjects in this post: Aurora Borealis and the interaction of icebergs with each other and with the avian life that inhabits them. I hope you enjoy these images.

Larry
