In addition to the Old Faithful Geyser, Yellowstone Park is best known as the Great Prism Spring. The Great Prism Spring is in the Middle Geyser Basin. The diameter of the big prism spring pool is 115 meters, and the water temperature is as high as 86°C. You will feel steaming when you approach it. It is the largest hot spring pool in Yellowstone Park and attracts thousands of tourists every year. In addition to the Great Prism Spring, the Middle Geyser Basin has Opal Pool, Turquoise Pool, and Wood Silk Geyser.
Walking in Huangshi Lake unknowingly exceeded the assembly time. I originally wanted to run back quickly, but after a few steps I felt breathless. I remembered that Huangshi Lake is more than 2,000 meters above sea level, so strenuous exercise will be more than usual. It feels harder, and there is a faint smell of sulfur in the air, so it is not recommended to run here, but to speed up the pace. Because I missed the assembly time in Yellowstone Lake, I also missed the 4:30 eruption time of Old Faithful Spring. Only temporarily change the itinerary to go to the Great Prism Spring and then watch the old faithful fountain eruption show at 6 o'clock. The Grand Prismatic Spring is located in the Middle Geyser Basin. This is a hot spring area with some small clusters, including four springs: Grand Prismatic Spring, Excelsior Geyser, and Turquoise Pool (Turquoise pool), Opal Pool (Opal Pool).
