The water fluctuations of the large prisms - Yellowstone Scenery 3 (below) Stopped on the path of the "Great Prism". For a long time, this is the largest hot spring in the United States with a diameter of about 100 meters and a water temperature of 85 °C. And the world's third-largest hot spring, watching it flood the ground to 2 tons of huge water per minute; these hot springs flow and paved a steaming, misty fairyland, known as the "Earth The most beautiful surface". In the absolutely original region of "Great Prism", everyone who comes here will see different paintings at different times and at different angles, seeing all the magic and all kinds of impossible . Perhaps because of a minor earthquake yesterday; perhaps because of the impact of the groundwater level; perhaps because the geothermal heat of the basin is again sprayed a lot; where the water surface of the large prism occurs every day Change, every day shows magic. When I was on the trail when the morning mist had not yet dispersed, as the thin clouds covered the sun, the clouds opened the sunrise, until the blue sky and white clouds left, the steam, light and shadow, ripples of the large prism spring surface were intertwined. Together, there is an epic and fascinating ecological picture. Although the closer to the Grand Prism Hot Spring, the more you can't see the full picture of the standard, but the closer the distance, the water wave under the front of the foot is at your fingertips, it seems to be able to appreciate the heat around it, it seems to be able to hear It is gentle and mysterious. I chose this "immersive" with an unparalleled feeling.
