GRAND PRISMATIC SOCKS
Out of stock
If you’ve ever been to Grand Prismatic, located in Yellowstone National Park, you know that it more than lives up to its name. The “Grand” part is easy to explain; it’s the largest hot spring in the United States, and third-largest in the world. “Prismatic” comes from the spectacular coloration, from blue to green to yellow, left behind by the mineral-rich water.
