It’s geology, all right. Lave flows, gravity flows (rock falling to pieces and creeping down cliff and down slope just because gravity says so), pumice drapes, stream-cut channels and sediment-filled basins–all under a sky preparing for the evening’s star show, lit by the last light of our local star, the star that beckons the moisture up from the ocean’s surface which is dropped as snow and collects here and turns into sculpting glaciers or streams. It’s geology at its best and most glorious.
