Hilo - Volcano National Park (2)

We had no sooner left the rim of Kilauea than we were in sight of the volcano's steam vents.

Here you can feel the steam from underground freshwater reservoirs as they rise to the surface! As waters below climb upward for miles beneath the surface, volcanic activity heats the water molecules and releases steam at the Earth’s surface. Another method for creating steam at these Volcanic Steam Vents occurs when rainwater seeps underground and is warmed by rocks heated from the lava below. The heated water then rises upward through fissures and condenses when it hits the cool air.

And that fast, we were off again.  This time we were going underground. Next post a Lava Tube!

Questions and comments always welcome.
