The Rock of Rock School

​The rock on the grounds of Rock School in Warren County, Ohio is a glacial erratic rock that was deposited in Warren County when the glacier receeded.  The rock is a metamorphic rock (a rock that went through changes to become a different kind of rock) and its scientific designation is gneiss (pronounced like the work nice).  Gneiss rocks show bands of different minerals that make up the rock, or you could say it displays gneissic banding.
