After driving around Crater Rim Drive in Volcano National Park (where we saw the crater, Halema'uma'u, and Thurston Lava Tube), we took Chain of Craters Road south towards the lava flows (yes, it's normal to drive towards active lava flows). Kilaeau has, for much of recorded history, been erupting more often than not. The current eruption started in 1983, and has been going continuously since then (Owen has dreamed of visiting this volcano since 1983!). Chain of Craters Road has been covered by lava several times, and is often later then dug out and repaved. One of the plusses of all the rain was the several beautiful rainbows like this one that we encountered along our drive. Underneath the rainbow is a lava flow from the late 60s/early 70s.
