Ledge Geyser is located in the Norris Geyser Basin, which is in the northwest region of the Park, just to the west of Canyon Village. This region not only is the hottest, but it is also the oldest and most dynamic thermal area at the Park. In fact, the highest recorded temperature in any geothermal area in Yellowstone was here and measured at 459°F at 1,087 feet below the surface.
This geyser is a big one, and anyone who has witnessed its eruption can tell you, it’s loud! It expels its hot water up to 125 feet high for around 220 feet. It is noisy because its water and steam must pass through a very narrow opening in the ground.
Yellowstone National Park preserves more than 10,000 hydrothermal features, of which more than 500 are geysers like Ledge.
