Pāhoehoe is basaltic lava that has a smooth, billowy, undulating, or ropy surface. These surface features are due to the movement of very fluid lava under a congealing surface crust. The surface texture of pāhoehoe flows varies widely, displaying all kinds of bizarre shapes often referred to as lava sculpture. (Taken from Wikipedia.)

We really liked these structures. We were never tired of their natural exhibition and we are fully aware that the following slideshow is redundant.
