This Virtual Cache is part Virtual Reward 3.0. From this point, you are looking at the Grand Prismatic Spring. The Grand Pristmatic Spring is the third largest Spring in the world, and is also located in the Midway Geyser Basin. Here is some information below about the Grand Prismatic. The Spring is nearly 370 feet in diameter and approximetly 160 feet deep.
The bright, vivid colors in the spring are the result of microbial mats around the edges of the mineral-rich water. 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.The deep blue color of the water in the center of the pool results from the intrinsic blue color of water. The effect is strongest in the center of the spring, because of its sterility and depth.
" All travel in thermal areas is restricted to NPS designated trails and boardwalks. Stay on boardwalks and designated trails. Do not touch any thermal features and keep foreign objects out of springs. Unstable ground and boiling waters make hydrothermal areas extremely dangerous."
