All of Lesbos doubles as an officially recognized geopark, deemed so for its abundance of petrified forests, the broken bones of giant sequoias that once circled the island in green turrets.

Of course, forests are not born fossilized. It happened by way of eruption, an era of angry volcanos pouring magma and ash over evergreen needling canopies. The forest froze like a deciduous Pompeii, bleeding silica into the dirt to make Lesbos fertile.

Petrification, the geological process by which something organic becomes mineral, is the only known method of becoming a rock. Ash decomposes when it touches water, flooding the earth with silica that, in turn, decomposes wood and takes its place. And so molecule by molecule, a log turns into something jeweled. Any plant can become a fossil, from grizzled stumps evolving into rose quartz to the curled witch-finger of a fern warping into amethyst. All it takes is determination. Bury yourself in ash, and you can do it too.
