Corono Lava Tube, Cueva de los Verdes, Lanzarote

A very nice image of a single lava tube (top) and its reflection (bottom) in a subterranean pool of water. The lava tube is in the order of 8 m in height and over 5 m in width. Given this is a bit of tourist attraction, there must be more similar such photos on the internet. Our primary interest was to study planetary analogs. For an interesting publication on the geology/biology of the lava tubes see: http://rdcu.be/GAJU
