#Gneiss boulder
I came upon this stream-polished boulder along the Quinebaug River, just below East Brimfield Reservoir near #Sturbridge, #Massachusetts. Because it has been transported and I just took a photo, I don’t know its origins…but it looks like either the Quinebaug or Marlboro formations, Ordovician and Cambrian, respectively. Laurentia, not Gondwana. Lovely banding, eh? Lens cap is about 4 cm in diameter.
