After a lifetime of collecting, studying, admiring and climbing on rocks, I have made an exciting petrologic discovery that answers that nagging, ages old question, especially in New England: “Why do rocks seem to multiply and grow?” I have discovered that rocks, like turtles, hatch from shells. In the photos here you can see some of them in the process of emerging from their shells. Also, rocks grow, and like snakes they shed their skin as they grow. You can also see some of the more mature rocks here shedding their skin.
Rocks mate in the spring and the young hatch in the winter when the cold speeds up their metabolism, after varying lengths of gestation periods depending upon the type of rock (whether igneous, sedimentary, or metamorphic), ranging from 10 to 100 years. That is why we have more rocks in New England than Florida, for example, where it is warmer year round. Of course there are rocks everywhere because we had an ice age about 20,000 years ago, which resulted in an explosive birth rate of rock populations around the globe. Since that time however, the warmer climates have lost and not been able to replace their rock populations, which are now mostly sand, while we in the Northeast always have plenty of fresh new rocks to move around, and build stonewalls, foundations and gardens with. Cape Ann seems to have the ideal climate for rock propegation and growth.
