A Paleogene-aged basaltic lava flow on the Isle of Staffa, Scotland (person standing on cliff top for scale). The bottom section of this cliff is volcaniclastic rock. The middle and top sections are two parts of a single basaltic lava flow; each part of the lava flow cooled differently, forming rock with different characteristics. The middle layer shows spectacular columnar jointing resulting from relatively slow cooling; the top layer has very irregular closely-spaced joints caused by more rapid cooling.
