This is a volcanic explosion crater about 150 feet deep and about 3,000 years old. The walls are composed of various materials including some bright red rhyolite. At the center lies a lake of vivid aquamarine. Although the caldera’s walls are fairly steep, it is possible to walk down within. I did so to get out from the extreme winds that were hammering the top edge of the crater. At times it felt like you could easily be blown over the edge. These winds would plummet down the walls and rake the surface of the water creating eerie sounds. Some more daring (stupid?) tourists enjoyed these conditions, purposefully leaning forward into the void only to be held in place by the strong wind, testing fate. If that wind were to shift just slightly…
The wind made it next to impossible to photograph from the rim, but I was finally able to find some vantage points by sheltering behind some large boulders.
