[Note Guidelines] Photographer's Note
The viscous pahoehoe lava, typical for Hawaiian volcanoes, flows slowly towards the ocean and cools down. The heat is exchanged at the surface, which is covered quickly by a folded, shiny black crust of solidified rock. This crust, looking like twisted ropes or overlapping folds and bulbs as seen in the workshop, is the trademark of pahoehoe lava. The solid crust becomes thicker and thicker with time and insulates the lava flowing beneath, preventing the heat transfer to the surface. In this way, the slow flowing lava can cover long distances underground and finally flow into the ocean. When the eruption ends, the fluid lava underneath the crust drains out, leaving behind a "lava tube". This phenomenon is extremely prevalent and numerous lava tubes are found beneath the surface of the lava fields. Long and wide tunnels like this one found in the proximity of the Kilauea Caldera are less common. The one depicted here is a few meters wide and a few hundred meters long, and part of its length is arranged for visitors. The last 300 meters can be easily visited as well but require a flashlight.

Hi Roland
Very insteresting picture and note... it is the first time I ever heard of a lava tube ! The warm colors (due to the lights ?) add to the atmosphere

Hi Roland
It was first the title which struck me as I visited some lava tubes in Australia. I like the textured effect of this shot, the light of the lamps and the way the eye is drawn along the path.

Hi roly
I find the big light on the left a bit distracting element in this photo as the exposure from rest of the photo is good but the area around this light seem to be overexposed ... besides that it is all good ... the depthness is good
and your note is very well written
tfs ... regards ... sarju

Hi Roland,

Wonderful capture of this lava tunnul. Amazing view down the tunnel and you captured this so sharp! The colors here are wonderful and the composition is great. The depth and perspective here is fantastic! Your note is also very interesting!

Greetings,
Ann

I've heard of lava tubes before, and even understood the concept of how they are created. This is the first time I've ever seen one that wasn't an illustration.
Excellent shot.
