Viðey
It is really hard to find detailed information in the web about this location. But what I have found I will share with you!
Two million years ago Viðey was an active volcano, which is known as the Viðey volcano. The rock of Viðey island is the oldest in the Reykjavík area.
At the end of the last Ice Age, 12–13.000 years ago, the sea level rose due to the melting of the glacial ice, and the island was inundated. When the sea level dropped, the island rose once more from the sea 9–10.000 years ago.
Viðey island is about 1.6 km in total area, comprising Heimaey (Home Island) and Vesturey (West Island), which are linked by a narrow neck of land or isthmus, Eiðið.
Spectacular columnar basalt rock formations can be seen along the shore of the island, especially near Eiðið.

Columnar Basalt
"During the cooling of a thick lava flow, contractional joints or fractures form. If a flow cools relatively rapidly, significant contraction forces build up. While a flow can shrink in the vertical dimension without fracturing, it cannot easily accommodate shrinking in the horizontal direction unless cracks form; the extensive fracture network that develops results in the formation of columns."(Source: WikiPedia)
Todo
Visit PH01 and PH02 and measure the density of the basalt lava stones here. Describe us in a few words (optional: and photos) in your Log how you have done it :-) Compare surface, density and write me your observations via Email.
Log terms
- Don't wait, just Log. But please send us an Email with the answers to the questions above.
- Please take some optional photos of you or your GPS at Waypoints PH01 and PH02 in front of the columnar basalt formations and add it to your Log.
Love Kate!
