 Lava Flow After hiking about three miles we were in position to see the live lava flow. The wind picked up at that point and I didn't have a tripod with me, so I braced the camera on solid rock and used the time release setting to permit a relatively stable shot. The time lapse caught steam vents (with gray smoke-like moving steam clearly visible throughout the lava field) and red-hot lava movement, making the photo a bit blurry. Nevertheless, the molten lava can be seen. Darker areas are hardening with the lava moving below the surface. Park rangers make it clear that lava rock is not stable near the flows and will not support much weight. Lava moves beneath the surface in 'tubes'. Essentially, the whole center of this photo is a combination of subsurface lava and above-surface flows. We didn't hike any closer to avoid incidents. ISO 100, 6s, f/14.0, 300mm of 70-300mm | |
