The Midway Geyser Basin in Yellowstone National Park is a captivating hydrothermal wonderland that showcases the raw power and beauty of the Earth’s geothermal activity. This small, yet remarkable area is home to several notable features that draw visitors from around the world, each offering a unique glimpse into the dynamic processes that shape the landscape.
Notable Features of the Midway Geyser Basin
Grand Prismatic Spring
The crown jewel of the Midway Geyser Basin is the Grand Prismatic Spring, the largest hot spring in Yellowstone and the third-largest in the world. Measuring an impressive 370 feet in diameter, this vibrant, multi-colored spring is a sight to behold. The striking hues, ranging from deep blues to vivid oranges and reds, are created by thermophilic (heat-loving) bacteria that thrive in the progressively cooler water around the spring’s edge.
Excelsior Geyser
Another notable feature of the Midway Geyser Basin is the Excelsior Geyser, a 200 x 300 foot crater that constantly discharges more than 4,000 gallons of water per minute into the Firehole River. Although it was once the largest geyser in the world, it is now a productive thermal spring, showcasing the dynamic nature of Yellowstone’s hydrothermal systems.
Turquoise Pool
The Turquoise Pool, a 100 x 110 foot pool, is named for its milky, white bottom and gem-like, blue-colored water. This pool is known for its opalescent iridescence, which is created by the interaction of the hydrothermal water with the minerals in the surrounding environment.
Safety Precautions for Visiting the Midway Geyser Basin
Exploring the Midway Geyser Basin requires visitors to exercise caution and follow established safety guidelines to ensure a safe and enjoyable experience.
