Photo by Stephen Alvarez @salvarezphoto | Loftheiller Cave, Iceland, is a permafrost-encrusted lava tube and one of the few lava tubes I know of that has permanent ice formations. Ice inside this cave grows slowly and is hundreds and maybe thousands of years old. The cave itself was created when fast-flowing molten rock drained through a lava field and left this void underground. The cave is now a product of fire and ice. #iceland #cave

[BIHAKUEN]UVシールド(UVShield)

katherineclausing Incredible. I love finding pictures of places that most people couldn't see otherwise. It's beautiful, peaceful, and also terrifying to look at and realize how untouched and changing it is.
