Five-Flower Lake, at an altitude of 2462 meters, is 450 meters long, 313 meters wide, and 9 meters deep. It is a barrier lake formed by a landslide and debris flow blocking a former glacial valley. Five-Flower Lake is the most colorful lake in Jiuzhaigou. The travertine, algae, aquatic plants, and dead trees on the lakebed, under different reflections and refractions of light, combined with the reflections of the blue sky, white clouds, green grass, and verdant forests in the lake, create a tapestry of colors—from pale yellow and emerald green to dark green, sky blue, deep blue, and navy blue—resembling a giant ornament inlaid with countless gemstones, shimmering and magnificent. Viewed from above, it resembles a peacock spreading its tail feathers.
