Sulfur stained gorge walls, smoking water, remnants of a 25 foot deep lava flow, and the constant reminder of the supervolcano beneath. Sound like the surface of Mars? No… that’s silly. There’s no rivers on Mars. That would be Calcite Springs on the famous Yellowstone River. Hydrothermal displays add to the uniqueness of the Yellowstone River, but that’s not all it’s known for. This river has hosted native tribes, explorers, and adventure chasers alike. The name ‘Yellowstone’ was translated from Minnetaree by Lewis and Clark on their famous expedition. These blue ribbon waters hold brown trout, rainbow trout, and the famous Yellowstone cutthroat trout. But don’t let the beauty fool ya, that supervolcano is still there just’a waiting.
