Did you know Rochester used to be underwater? 🌊 12,000 years ago, the Pinnacle Range (Cobbs, Highland, Pinnacle) wasn’t just hills—it was the southern shoreline of Glacial Lake Iroquois. 🧊 That’s why the hills are made of sand, not rock! 🏖️ #RochesterHistory #GeologyTok #RocNY #FingerLakes #Glacier
