Location: Mauna Loa, Big Island, Hawaii
This won't win the prize for the prettiest photo ever posted on this blog, but I thought it would be a good follow-up to my previous post on pāhoehoe lava from Mauna Loa volcano. This image is a closer view of the surface of pāhoehoe lava, which has cooled and hardened. This, too, is part of a 1935 flow from Mauna Loa. As you can see, a hardy lichen has sprouted from a crack, much as a weed would sprout from sidewalk cracks.
