At Midway Geyser Basin, you can watch Yellowstone’s story unfold in water.
The Firehole River moves north through the landscape because water always follows gravity, flowing downhill while beneath your feet, heat from Yellowstone’s volcanic system brings water back to the surface. And those brilliant bands of orange, yellow, and green? They’re living microbial mats, communities of heat-loving organisms thriving in conditions where most life couldn’t survive. In Yellowstone, even the colors are alive.
