The next afternoon we went on a ranger guided tour of the lava tubes.
It was about a mile walk to get to the tubes and on the way the ranger pointed out some of the plant life in the field. Several flowering plants and a tree called the Limber Pine, which gets it's name from being limber enough to with stand the strong winds and heavy winter ice.
Then down into the cool lava tube; did I mention that it was 89 degrees outside while we walked the mile out there?
The white in the upper right corner is looking up at the sky from inside the cave. The orange color in the lava was from a high iron content. After the hike and dinner there was another beautiful sunset.
