We were walking through the path of where the lava flowed from the volcano. Our guide told us that the lava was like water – it takes the path of least resistance and flows downhill.
As it flows, it moves very fast and hits up against things and as lava separates from the flow, it hardens as it begins to cool. That hardening leaves a wall in the valley. The wall was easily 60-100 feet tall. And the best part is that the wall is rounded, curving in on itself, not straight up and down. Very cool.
We had the opportunity to look as some of the hardened lava pieces and examine them.
And we learned about the different colors in the lava rocks as well.
