Midway Geyser Basin, Yellowstone National Park, Wyoming, USA

Midway Geyser Basin contains a small collection of mammoth-sized springs. Midway is part of the Lower Geyser Basin, but because of its isolated location between the main features of Lower and Upper geyser basins it became known as Midway.

Rudyard Kipling, who visited Yellowstone in 1889, immortalized this basin by referring to it as “Hell’s Half Acre.” Even today it is still remembered by that name. Despite its small size Midway possesses two of the largest hot springs in the world.

Grand Prismatic Spring, nearly 370 feet in diameter, sits upon a large mound surrounded by small step-like terraces. The other feature, Excelsior Geyser, erupted nearly 300 feet high before the 1900s. It is now a dormant geyser and is considered a hot spring, discharging more than 4050 gallons of boiling water per minute.

Other colorful springs include Turquoise and Indigo springs, known for their pale and dark blue colors. Across the Firehole River from Excelsior and Grand Prismatic springs are a series of small isolated, pristine springs and mud pots. The Rabbit Creek drainage possesses some colorful and unusual features and most are unnamed. Caution should be exercised while exploring this vicinity since the ground is unstable and trails are not maintained.
