Quick Summary

Norris Geyser Basin is a hydrothermal area within Yellowstone National Park in Wyoming, United States. It is known for its exceptionally hot and acidic thermal features, including Steamboat Geyser, the world's highest-erupting geyser, capable of ejecting water over 300 feet high. This basin is one of Yellowstone's many hydrothermal areas, which collectively represent about half of the world's known hydrothermal features. These features, including geysers, hot springs, and fumaroles, are a result of the region's volcanic activity and fractured crust, allowing groundwater to interact with magma.1
