We took a long drive down to Volcano National Park where we started with a hike in Iki (=small) crater. Later in the visitor center I learned that we were walking on what was a lake of lava less then 100 years ago. I’m not sure the images can begin to capture the contrasts of the place. To my eyes so much of the landscape looked dark, yet the landscape is covered with fine-silica which reflect a bright shining light which dominates the pictures. It took a bit of post-processing to get the pictures to resonate with what I felt I saw.
The hike starts with a rain-forest-ish walk around and then down into the crater.
then the crater’s lunar surface appears
followed by a short walk into a lave-tube cave 
and then another drive took us down to the shoreline where vast black lava fields meet the pounding waves of the ocean … a collission of static and dynamic forces resulting in … life! in the distance you can see steam rising from where hot lava is currently flowing into the ocean.
It was fascinating to learn from the visitor center video that the Hawaiian island were (and are still being) formed by the same volcano. The under-water structure that is the Hawaiian islands is drifting east (away from the USA) ~10cm a year. The volcano is like the head of a 3D printer that is printing islands that are then drifting east … creating (ongoing!) the chain of islands.
