Basalt, A Hexagonal Rock Formation

Basalt, an igneous rock formed by the heat of volcanoes, has a distinct hexagonal structure.

This informational sign from the Columbia Gorge in Oregon explains the volcanic process in which basalt is formed. I have kind of messed the image up by collaging it but you get the idea, no?

  2. So cool! The sign about how it forms is fascinating. I’ve seen the same type of formations on Staffa Island in the Inner Hebrides, Scotland. Hope to make it to the sister island in Ireland soon. 🙂 Thanks for joining the challenge, again!
