Lady Knox Geyser, Geothermal attraction in Wai-O-Tapu, New Zealand
Lady Knox Geyser produces a column of water reaching heights of 20 meters during its regular eruptions in the Waikato thermal region of New Zealand.
The geyser received its name from Lady Constance Knox, the daughter of New Zealand's 15th Governor, marking its connection to colonial administration.
The discovery occurred in 1901 when prisoners at New Zealand's first open prison found that adding soap to the water triggered dramatic eruptions.
The geyser follows a consistent schedule with daily eruptions at 10:15 AM, allowing visitors to plan their observations of this natural phenomenon.
Staff members initiate the eruption by adding a specific surfactant to the vent, creating a reliable schedule unlike natural geysers in the region.

Geysers represent some of the most visible expressions of hydrothermal activity, occurring where underground water reservoirs are heated by magmatic sources. Yellowstone National Park in Wyoming holds more than half of the world's known geysers, including Old Faithful with its reliable eruptions every 90 minutes and Steamboat, the tallest active geyser on Earth. Iceland offers the Haukadalur Valley, home to the namesake Geysir and Strokkur, which erupts every few minutes. The high plateau of El Tatio in Chile sits at 14,100 feet (4,300 meters) and forms the highest elevation geyser field in the world. Other notable locations include the Whakarewarewa thermal area in Rotorua on New Zealand's North Island, where the Pohutu geyser performs regularly, and the Valley of Geysers in Russia's Kamchatka Peninsula. These sites demonstrate the ongoing volcanic activity beneath the Earth's surface and attract visitors interested in observing natural thermal phenomena. Eruption patterns vary in frequency and intensity, with some geysers following predictable schedules while others remain irregular.
