Etna, the sequel<\/p>\n

4. Types of Rock present: each eruption produced the same rock:<\/p>\n

The rocks have a lot of holes; they look like fossilized honeycomb. They were black, but some were a little bit read because of the iron (about 10% the geologist said), and the most recent ash a little bit like oily soap color.<\/p>\n

5. Types of flow. Most of the lava was a’a — that means it would take an hour to cross a field, it sounds crunchy to walk on, because the rocks are not set in place and move around, and grind against each other, and are sharp. This from 2002:<\/p>\n

But I also saw some pahoihoi lava, which means it was smooth and flat, or smoother and flatter and was easier to cross.<\/p>\n

The smoother stuff was hotter when it came out of a vent just in front of me…<\/p>\n

The less smooth makes wave formations!<\/p>\n

5.5 Plants and animals! This plant, called Holy Thorn, only grows in Mt Etna’s soil; it has two-inch thorns, and the Catholics believe that the thorn-crown that Jesus wore was made of Holy Thorn. It is very common on Mt Etna.<\/p>\n

There were a lot of pine trees, and a lot of birch trees. Birch trees are not common in sicily, but remain here from the Ice Age, when northern plants made it south — because of Etna’s unusual soil and lower temperature.<\/p>\n

As for animals, not many live there beside rabbits, foxes, wildcats, porcupines. Wolves have been hunted to extinction in Sicily; the last one was shot in 1928. There are no large mammals. I did see a hawk.<\/p>\n","protected":false},"excerpt":{"rendered":"
