Geologically speaking, nature did a good thing for the planet fifteen million years ago by giving us the volcanic island of Iceland. Of course, it took humans a long time to discover it. It wasn’t until the 9th century CE that a fugitive from Norway named Ingólfur Arnarson approached the island by boat. Throwing two carved logs overboard, he declared that wherever the gods decreed they would touch land he would settle. That spot became known as Reykjavik (Smokey Bay) due to the steam rising from its fissures and thermal pools. Today, it is that steam that heats the water that supplies the bathroom shower and fills the kitchen sink. Its faint odor of sulfur betrays its source.
