Today on #NationalParkWeek I’m featuring Yellowstone’s largest hot spring, the Grand Prismatic Spring. It measures ~370 feet in diameter, over 121 feet deep, and gets its name from the rainbow colors that are dispersed when white light travels through a prism. #Yellowstone150 https://t.co/3V3kRetAj5 — PolitiTweet.org
