Let’s go back to a few years before we bought our cabin—390 million to be exact. It was the middle of the Devonian period, more than 150 million years before the first dinosaurs roamed. Terrestrial earth consisted of just two primary landmasses: Gondwana in the Southern Hemisphere and Laurasia to the North. The first vascular plants, including ferns and horsetails, were busy forming the world’s earliest forests.
