East of Pittsburgh summer nights are clear above the Monongahela and Youghiogheny rivers. It is a major temptation to slip into the water and disappear. Not as a way to leave the world but to delve deeper—to float in silver-black waters lit by moonlight and let your mind drift. In winter the sky above the rivers opens to the universe. Jupiter and Saturn are visible first. Neptune reveals itself later. It’s a reminder that bodies have long played a part in these valleys. Bodies of water offering passage. Celestial bodies guiding ambitious men westward. Bodies of the Indigenous people who first settled the land. Bodies of the laborers who transformed these hills and hollows into the Silicon Valley of the Industrial Age. Bodies of the dead and bodies of the living and bodies of those yet to be born.
