Midway geyser basin Yellowstone

Midway Geyser Basin is small but spectacular.

Excelsior Geyser is a 200 x 300 foot crater that constantly discharges more than 4,000 gallons of water per minute into the Firehole River.

Grand Prismatic Spring, Yellowstone’s largest hot spring, is 200–330 feet in diameter and more than 121 feet deep.
