Beauty Pool, located in the Upper Geyser Basin of Yellowstone National Park, is a striking geothermal feature renowned for its vibrant hues and intricate formations. The pool, which measures about 16 feet in diameter, showcases a brilliant spectrum of colors ranging from deep turquoise in the center to vivid yellow and orange near the edges. These colors are a result of thermophilic microorganisms that thrive in the hot, mineral-rich waters.
Hot springs are the most common hydro-thermal features at Yellowstone National Park.  They vary from frothing mocha-like boiling water to clear and calm pools of tremendous depth.
Visitors get a close up view of one of more than 10,000 thermal features in Yellowstone. Research on heat-resistant microbes in the park’s thermal areas has led to medical, forensic, and commercial uses.
