The highlight of my May 2025 trip to Yellowstone was finally getting to see and experience the colors of Grand Prismatic Spring from the Grand Prismatic Spring Overlook. Over the years I've made numerous attempts all of which failed for one reason or another. If you go too early, and there's no wind, the steam masks the formation. If you go to late, you can't find a parking spot. If there's bear activity, they close the trail. When you do make it up and get the chance to look down at the Grand Prismatic Spring from the overlook, you see a riot of fiery oranges, golden yellows, deep reds, and brilliant turquoises, appearing almost supernaturally vivid against the soft, falling snow. It was like the earth itself was exhaling beauty, and I was lucky enough to be there to inhale it! Standing on the overlook, enveloped by a gentle snowfall, felt like I was witnessing a sacred, living, and breathing masterpiece of nature. The falling snow added a layer of magic, making the already vibrant colors of the Grand Prismatic Spring feel even more alive, a true testament to the raw, untamed artistry of nature. The bright, vivid colors in the spring are the result of "microbial mats of thermophilic bacteria" around the edges of the formation. The mats produce colors ranging from green to red; the amount of color in the microbial mats "depends on the ratio of chlorophyll to carotenoids and on the temperature gradient in the runoff." In the summer, the mats tend to be orange and red, whereas in the winter the mats are usually dark green. The center of the pool is sterile due to extreme heat: 188.6 degrees in the center...

Ascending to the Grand Prismatic Spring Overlook for the first time in Yellowstone National Park was a breathtaking experience that was worth every effort.
