- Thousands of years ago, cataclysmic floods inundated the Pacific Northwest and sent glaciers sailing across what is now Oregon.
- When these glaciers melted, they left behind large pieces of rock carried from hundreds of miles away.
- Known as glacial erratics, these rocks differ in size and composition from native rocks.
- The largest known glacial erratic in the Willamette Valley perches serenely atop a hill near McMinnville and weighs around 36-tons.
- The massive rock was transported from Canada.
