On the last leg of our trip, we stayed on the "big island" (the island actually called Hawaii). There we spent a couple days at Volcanoes National Park. A lot of people are lucky enough to be able to walk right up to active surface lava flows while there, but for the last couple months there has been only a tiny, remote, and inaccessible area with such flows. We did see the flows by evening, but only as embers creeping along the tops of cliffs on the horizon (we couldn't get closer than about 6 miles from them).

The park itself was still fascinating, as we got to walk across an old crater floor, through a lava tube, and over all sorts of formations from hardened past flows.



This particular flow wasn't very considerate of local traffic routes at the time.
