Into the fog...
Consisting of two large pools, Midway’s main attraction is undoubtedly Grand Prismatic Spring, however Excelsior Geyser (or rather, its crater) is the first feature we pass on the boardwalk. A steaming body of teal water running off into the Firehole River, Excelsior has been like this for most of its recorded history. For a time though, it was the largest geyser in the world.
Some of its eruptions were estimated at 300 feet tall, 300 feet wide. Just imagine: a football-length sheet of water bursting from the ground, rising the length of a football field. You can imagine the sound it must have made when it hit ground again. This was the case for fortunate visitors in Yellowstone National Park between 1878 and 1890.
