Sitting in the Arnold Arboretum last month, I watched the full moon rise above the pines. Several unseen critters were doing the same nearby.
Representing the 13 full moons every year, these luminous shells each vary in detail like the lunar stages. They're suspended from delicate Maine driftwood and ultimately secured by a pine cone which I found while hiking through a small area in the Blue Hills that had been subjected to forest fire. Most of the trees were charred and ashen, giving things a silvery hue. Resting on the top of the cone and each piece of wood sits a tiny shell.
