A brand new, insanely blue hot spring just popped up in Yellowstone and nobody saw it coming! Geologists found this 13-foot-wide pool in Norris Geyser Basin during routine checks—turns out, it probably formed after a series of underground steam ‘burps’ literally blew the earth open between December and February. The water’s a toasty 109°F and the whole thing looks unreal. How long before it’s all over your feed? #News #Yellowstone #NatureMystery
