大稜鏡Grand Prismatic Spring，是黃石公園裡最有名的溫泉之一。大稜鏡是黃石的代表作，就像黃山的迎客松一樣的名片。人們可以沒去過黃山，但你一定看到過迎客松的形象；同理，人們可能沒去過黃石，但大稜鏡的全景圖一定是出現在美國旅遊首榜上的。 多彩繽紛的大稜鏡，直徑大概有100米，是美國最大，世界第三大的溫泉，有近50米深，水溫高達85℃，每分鐘約會湧出2000升泉水。在飄着清雨的天空中，顯得更加熱氣騰騰。 行人能看到的角度，是一個側平面，並不是在各大宣傳冊上看到的空中全景。 但即使是只窺一角，便已感受到其氣勢逼人，有一種不識廬山真面目，只緣身在此山中的感覺。 又有一種，一般大神級別的景色都不會讓人很輕易的看到。全天的遊覽，就在此處停留的幾分鐘里，下了雨，此時的氣候，風雨交加，讓人感覺置身自然的懷抱中，內心隨着天邊雲，風中雨，瀟洒澎湃。 我一直堅信，旅途中所有的遇見都是緣分，盡情享受這天地間風雨與熱氣交相輝映的全方位體驗，此處，堪稱經典！ 以下這段是在網上聽說：“大稜鏡溫泉的美在於湖面的顏色隨季節而改變，春季，湖面從綠色變為燦爛的橙紅色，這是由於富含礦物質的水體中生活着的藻類和含色素的細菌等微生物，它們體內的恭弘=叶 恭弘綠素和類胡蘿蔔素的比例會隨季節變換而改變，於是水體也就呈現出不同的色彩。”所以，在我們到達的夏季，這裏的恭弘=叶 恭弘綠素含量相對較低，顯現橙色、紅色，或黃色。但聽說到了冬季，由於缺乏光照，這些微生物就會產生更多的恭弘=叶 恭弘綠素來抑制類胡蘿蔔素的顏色，於是就看到水體呈現深綠色。 和大稜鏡比起來，周圍還有三處小熱泉，雖沒有大稜鏡大氣，但依然精巧美麗。

美國最為著名的景點之一，位於素有號稱“美洲脊樑”的落基山脈，跨越三個州，是世界上最大的火山盆地公園。其中遍布各種溫泉，而大稜鏡溫泉是最為出名，也是最漂亮的溫泉了。在夏季熾烈的陽光照射下，溫泉水面蒸騰，帶着反射的藍光，與周邊硫磺和其他礦物質顯現的各種色彩，形成了七彩大稜鏡的獨特景觀，現場讓人流連忘返。

大稜鏡溫泉，是美國黃石國家公園最大的景點，長長的棧道，高高的山坡，都是川流不息的遊客。大稜鏡，又是黃石公園最美的景觀，赤橙黃綠青藍紫，都呈現在眼前，真正感受到了美崙美奐，絢麗多彩~

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.

The Great Prism Hot Spring is the landmark scenic spot of Yellowstone Park, but if you want to see the propaganda pictures on the propaganda picture, you have to watch it by helicopter in the air, or climb the nearby mountain when time permits, the scenery will be more perfect.

The Big Diamond Mirror Hot Spring in Yellowstone Park, known as the "most beautiful surface of the earth", is the largest hot spring in the United States and the third largest in the world. It is also the most attractive hot spring in Yellowstone Park. Walking along the pavement, it has a warm atmosphere. To get a panoramic view of the turbot mirror, climb around the hillside behind it, and there is a path beside it. I don't think I'm in trouble, but I have to pay attention to safety. It's the best visual overlook of the turbot mirror to get the feeling of postcards. The panoramic beauty of the turbot mirror is so shocking that only when you are there can you realize the magic of nature.

In the sunshine, the vast folded ground around the prism emits magical reflections. It's amazing. The colours are different from different angles. Everyone who comes here will see different color pictures at different times and from different angles. In this moment, time and light may not be the best, but it is the only one. The closer we get to the Great Prism Hot Spring, the less we can see its standard panorama, but at close range, we can feel the heat of the Great Prism Spring vapor, and hear its gentle pulsation. It is a wonderful feeling that we can not see in the photos and are in the scene.

The most amazing thing about the Great Prism is that the color of the lake changes with the seasons. It is known as the "Eye of Yellowstone ", also known as" the most beautiful surface on earth. Personally, I think it's one of the most worthwhile scenic spots in Yellowstone Park, but if you just look at it from the perspective of the map, because with the lake level and rising water vapor, you can't see the classic scenery like that in National Geographic and various travel website magazines. If you want to take a picture of the Great Prism, you have to go this way - "After going out of the Great Prism scenic spot, drive about 2.5 kilometers in the old faithful direction. On the right hand side of the road, there will be a sign indicating a scenic spot called Fairy Falls, with a parking lot at the end. Stop and walk into the next iron bridge. Then it's a long road paved with cinder. It's about 15-20 minutes'walk (about 1000 meters). You'll find the big prism just seen in Zhongquan District is on your right hand, and there's a small slope on your left hand. There are many fallen trunks on the slope, and there's a mud road stepped out artificially. That's the way to climb mountains. "There's no road in the world at all. It is absolutely a true portrayal of this place. To say the road, there is no way at all. They are all climbing up the trunk on the ground. It's harder to get down the hill. You have to move carefully. It takes about 30-40 minutes to go up and down the mountain, basically using both hands and feet. We started from the parking lot and went back to the parking lot for 75 minutes. When you looked at the big prism, you really felt that all the hard work was worthwhile. And God was so helpful that you could take a panoramic view of the big prism in the sunshine. There was no regret about this trip. It was the best time to take a picture around 2 o'clock at noon, because the temperature was the highest and the water vapor would be much less. It's very difficult to go up the hill, but it's even more difficult to go down the hill. We can't take care of the cleanliness of our clothes and trousers. So if we want to take a panorama, we must be prepared mentally. This road is not easy even for adults, let alone for children, but also for girls. We should definitely give praise to the children's performance, even though the clothes and trousers are all dirt.
