Castle Geyser erupts with the colorful bacteria mats of Tortoise Shell Spring in the foreground. Castle Geyser reaches 60 to 90 feet in height and lasts 20 minutes. While Castle Geyser has a 12 foot sinter cone that took 5,000 to 15,000 years to form, it is in fact situated atop geyserite terraces that themselves may have taken 200,000 years to form, making it likely the oldest active geyser in the park.
