CUEVA DE LOS NATURALISTAS
Got to explore a different lava tube on Lanzarote this time. Naturalistas is a large walking sized tube that is situated on the center of the island on the fringes of the large lava flows from the 19th century eruptions. This spot is close to one of the sinkhole entrances. A large column in the center of the passage was making the lava part ways around it and you can see the movement in the surface of a river of now solidified rock as it did. Being inside this tube alone and at midnight right out in the wilderness of the island was a enlivening experience, a feast for the senses.
Below is a shot from one of the large bends in the passage and one of the best spots to see the flow in the river of molten rock, you can quite literally see the movement in the surface features and the cracks that appeared as the flow cooled and stopped moving.
Lava tubes form when a river of molten rock is cooled by the air temperature along its surface. The lava cools quickest there and forms a thin roof whilst the still molten lava flows beneath. Eventually the eruption stops and the molten rock flows through the tube and leaves behind a hollow space. Many lava tubes are often very close to the surface as a result.
Shot using a very laborious technique where the light source is placed to light a specific part of the scene and then moved to light another spot and then again until all parts you want have been lit, afterwards the scene is blended together in PS to create the finished composite.
Thanks for looking.
