Morning Glory Pool, Hot spring in Upper Geyser Basin, US
Morning Glory Pool contains multicolored bacterial mats in concentric rings, ranging from deep blue at the center to orange at the edges.
Named in 1883 by Mrs. E. N. McGowan, who initially called it Convolutus after the Latin name for the morning glory flower.
The pool serves as a natural laboratory for scientists studying thermophilic bacteria that survive in extreme temperature conditions.
The water temperature reaches 157.6 °F (69.8 °C), and visitors must stay on designated boardwalks to maintain safety and preservation.
Objects thrown into the pool over decades have reduced water circulation, transforming its original blue color into a spectrum of yellow and orange.

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.
