This crater last erupted in 1959. There is still molten lava a few hundred feet below the surface.
Steam vents are visible all over its surface. We took a hike down into and across its surface.

Winny hiking along the crater surface. Note the steam vents on both sides of the photo.
Mark hiking along the surface
Mark feeling the temperature of the rocks on the surface. Most are hot due to the steam underground.
The rainforest above the crater is very hot and humid.
