Grand Prismatic Spring in Yellowstone National Park is located in Midway Geyser Basin and has the distinction of being the park’s largest hot spring and the Jewel of the West. It measures approximately 370 feet in diameter and is over 121 feet deep. A written description of the spring made by fur trapper Osborne Russell in 1839 makes it the earliest described thermal feature in Yellowstone.
