Big Prism Grand Prismatic Spring, one of the most famous hot springs in Yellowstone Park. Big Prism is a representative work of Yellowstone, like a business card of Huangshan's welcoming pine. People can never go to Huangshan, but you must have seen the image of the welcoming pine; Similarly, people may not have been to Yellowstone, but the panorama of the Great Prism must have appeared on the top US tourism list. The colorful prism, about 100 meters in diameter, is the largest and third largest hot spring in the United States, nearly 50 meters deep, the water temperature is as high as 85 ℃, and 2,000 liters of spring water are poured out every minute. In the rainy sky, it looks more steamy. The angle that pedestrians can see is a side plane, not the panoramic view of the air seen on the major brochures. But even if it is only a corner, it has felt its momentum, and there is a feeling of not knowing the true face of Lushan, just being in this mountain. There is another kind of general God-level scenery that will not be easy to see. The whole day of sightseeing, just a few minutes of staying here, it rained, the climate at this time, the wind and rain, people feel in the arms of nature, with the sky clouds, the wind and rain, the chic. I have always believed that all encounters during the journey are fate, and enjoy the full experience of the wind and rain and heat between the world. Here, it is a classic! The following paragraph is heard on the Internet: "The beauty of the big prism hot spring is that the color of the lake changes with the season, and in spring, the lake changes from green to brilliant orange red, which is due to microorganisms such as algae and pigment-containing bacteria living in mineral-rich water bodies. The ratios of chlorophyll and carotenoids in their bodies change with the seasons, so the water body takes on a different color. "So, in the summer we arrive, the chlorophyll content here is relatively low, showing orange, red, or yellow. But in winter, due to lack of light, these microorganisms produce more chlorophyll to inhibit the color of carotenoids, so they see the water body appear dark green. Compared with the big prism, there are three small hot springs around, although there is no big prism atmosphere, but still exquisite and beautiful.

One of the most famous attractions in the United States, located in the Rocky Mountains known as the "American Ridge", spanning three states, is the world's largest volcanic basin park. It is full of hot springs, and the Great Prism Hot Spring is the most famous and beautiful hot spring. Under the intense sunlight in summer, the hot spring water transpiration, with reflected blue light, and various colors displayed with surrounding sulfur and other minerals, formed a unique landscape of colorful prisms, and the scene made people linger.

The Great Prism Hot Spring is the largest attraction of Yellowstone National Park in the United States. The long plank road and high hillside are all endless tourists. The Great Prism is the most beautiful landscape of Yellowstone Park. The red orange, yellow, green, blue and purple are all presented in front of you. I really feel the beauty and beauty.

Check in, view, feel the magic of nature, and enjoy the beauty of leisure.

This is the most magical hot spring in Yellowstone Park. It is impossible to see the panoramic view of the Great Prism Spring just along the outer walkway. Close viewing of the big prism will be affected by rising steam and wind, which greatly reduces the viewing effect. The best angle to look at a big prism is to look down. If you want to see the whole picture of Yellowstone's beautiful big eyes, you have to climb the mountain behind the Great Prism Spring. Driving southeast along the highway, there is a parking lot called fairy falls. After crossing the iron bridge, walking right and along the riverside road for ten minutes, you can see the big prism rising on the right hand side. There are many talented people on the left side of the mountain. It's not very scary. After ten minutes, you can climb the platform on the mountain and see the panorama of the big prism. There are trails in the Grand Prism Scenic Area, but they are not very clear because of the transpiration of hot air.

When the sun is shining, you can see that the steam above the pool is blue and red by the pool water and the red mushroom moss on the edge of the pool. Because of its size, standing on the side of the road can not take a picture of the whole pool, you can go to the opposite hill to see the whole pool (from an article - "Midway Basin's parking lot to the south, there is a small sign beside the parking lot that says - "quot; Fairy Falls ", from here you can climb up the mountain by gravel path, which is the best view besides aerial photography. )

The big prism is also called the big rainbow, because it is from the center of the water surface to the edge, with red, orange, yellow, green, blue and purple, and other similar colors of the rainbow, brilliant, incredible. The dramatic colour of the Great Prism Hot Spring is composed of the interaction of physics, chemistry and biology. Blue is visual, while orange and Brown are made up of bacteria living near boiling points. The color of the lake surface of the Great Prism Hot Spring changes with the seasons. In spring, the lake surface changes from green to brilliant orange-red. This is due to algae and pigmented bacteria living in mineral-rich waters. The proportion of chlorophyll and carotenoid in the lake surface changes with the seasons, so the hot spring water presents different colors. In summer, chlorophyll content is relatively low, showing orange, red, or yellow. But in winter, due to the lack of light, these microorganisms will produce more chlorophyll to inhibit the color of carotenoids, so you can see that the water is dark green. Midway Geyser Basin has a fairy trail in the parking lot, from which you can climb the top of the mountain on foot and take a panoramic view of the Great Prism Hot Spring. Far from the flat ground to the big prism, in the severe weather, the ground actually emits a colorful sunlight, is the water vapor to refract the rainbow of the big prism. We have seen aerial views of the Great Prism in countless magazines and posters to understand the significance of this classic landform to the entire American geography and National Park system.
