A near-vertical look at the margin of the Kahauale‘a 2 flow. Numerous trees surrounded by the slowly moving pāhoehoe lava were burned through at their base, causing them to eventually fall over onto the flow itself. In many cases, by the time the tree falls over, the lava crust is no longer hot enough to ignite the wood, leaving a relatively intact tree resting on the flow surface. These fallen trees can make mapping the flow margin on foot very difficult.
