What is Morning Glory Pool?
Morning Glory Pool is a geothermal hot spring located in Yellowstone National Park, specifically within the Upper Geyser Basin area. Known for its vibrant, multicolored appearance, the pool is a result of unique geological and biological processes that create a breathtaking natural phenomenon. The pool gets its name from its resemblance to the morning glory flower, with its circular shape and vivid hues mirroring the blossom's appearance.
At its core, Morning Glory Pool is a natural result of Yellowstone's geothermal activity. The park itself sits atop a supervolcano, and the heat generated beneath the earth's crust gives rise to numerous geysers, hot springs, and thermal pools, including Morning Glory Pool. With an average temperature exceeding 170°F (76°C), the pool is inhospitable to most forms of life, except for thermophilic microorganisms that thrive in extreme heat.
These microorganisms play a pivotal role in giving the pool its unique colors. Depending on the temperature and mineral composition of the water, different species of microorganisms populate various regions of the pool, creating a gradient of colors that range from deep blue in the center to fiery orange and yellow along the edges.
History and Discovery of Morning Glory Pool
The history of Morning Glory Pool dates back to the late 19th century when Yellowstone National Park was first designated as a protected area in 1872. Early explorers and settlers were captivated by the pool's beauty, and it quickly became a popular site for visitors. Originally named "Convolutus" by Mrs. E. N. McGowan in 1883, after the Latin word for the morning glory flower, the pool's current name reflects its striking resemblance to the plant.
Over the years, the pool has undergone significant changes, both natural and human-induced. Early visitors often threw coins, rocks, and other debris into the pool as souvenirs, unknowingly clogging its thermal vents. This led to a decrease in water temperature, which in turn altered the types of microorganisms that could survive in the pool. As a result, the once-dominant deep blue color gave way to a broader spectrum of oranges, yellows, and greens.
Efforts to preserve the pool began in the mid-20th century, as park officials recognized the impact of human activity on its delicate ecosystem. Today, Morning Glory Pool is a symbol of both the beauty and fragility of Yellowstone's geothermal features, serving as a reminder of the importance of conservation and responsible tourism.

Why is Morning Glory Pool so Colorful?
The vibrant colors of Morning Glory Pool are a result of a fascinating interplay between heat, water, minerals, and microorganisms. At the center of the pool, where temperatures are highest, the deep blue color is caused by the water's absorption and scattering of sunlight. The high temperatures in this area make it inhospitable for most microorganisms, leaving the water clear and allowing the blue wavelengths of light to dominate.
As the water cools toward the edges of the pool, different species of thermophilic microorganisms, or "thermophiles," begin to thrive. These microorganisms contain pigments that help them absorb sunlight and produce energy, giving rise to the pool's yellow, orange, and green hues. For instance:
- Yellow and Orange: These colors are often associated with bacteria that thrive in moderately hot conditions and contain carotenoid pigments.
- Green: The green areas of the pool are typically populated by chlorophyll-containing microorganisms that perform photosynthesis.
In addition to microorganisms, the pool's mineral content also contributes to its colors. Minerals such as sulfur, iron, and silica can interact with the water and microorganisms to create unique patterns and hues. This dynamic ecosystem is a testament to the adaptability of life and the complex interactions that shape our natural world.
The Geology Behind Morning Glory Pool
Morning Glory Pool is a prime example of Yellowstone's geothermal activity, which is driven by the park's location atop a volcanic hotspot. This hotspot generates immense heat beneath the Earth's surface, creating a network of underground chambers filled with pressurized water. When this water finds its way to the surface through cracks and fissures, it forms geysers, hot springs, and thermal pools like Morning Glory Pool.
How Do Microorganisms Contribute to the Pool's Colors?
Microorganisms play an integral role in the vibrant colors of Morning Glory Pool. Thermophiles, which are heat-loving microorganisms, thrive in the pool's extreme temperatures, creating a living tapestry of colors. These organisms are adapted to survive in conditions that would be lethal to most life forms, and their pigments are responsible for the pool's striking hues.
For example, cyanobacteria are a common type of thermophile found in Morning Glory Pool. These microorganisms perform photosynthesis, producing oxygen and absorbing sunlight, which gives the pool its green and yellow colors. Other types of bacteria and archaea contribute to the orange and red hues, depending on their specific pigments and metabolic processes.
Is Morning Glory Pool a Hot Spring?
Yes, Morning Glory Pool is classified as a hot spring, which is a type of geothermal feature commonly found in Yellowstone National Park. Unlike geysers, which erupt periodically due to pressure buildup, hot springs like Morning Glory Pool maintain a more consistent flow of hot water. The pool's high temperature and mineral-rich water make it an ideal habitat for thermophilic microorganisms, which in turn create its vivid colors.
Environmental Threats to Morning Glory Pool
Morning Glory Pool faces several environmental threats, both natural and human-induced. These include:
- Debris and Litter: Visitors have historically thrown coins, rocks, and other objects into the pool, clogging its thermal vents and altering its water temperature.
- Climate Change: Rising temperatures and changing weather patterns can affect the pool's delicate balance of heat and water flow.
- Human Activity: Increased foot traffic and tourism can lead to soil erosion and other forms of environmental degradation in the surrounding area.
What Makes Morning Glory Pool Unique?
Morning Glory Pool is unique for its combination of geological, biological, and aesthetic features. Its vibrant colors, shaped by thermophilic microorganisms and mineral-rich water, set it apart from other geothermal features in Yellowstone. Additionally, its history of human interaction and conservation efforts make it a poignant symbol of the challenges and responsibilities associated with preserving natural wonders.
How to Visit Morning Glory Pool
To visit Morning Glory Pool, head to Yellowstone National Park's Upper Geyser Basin. The pool is accessible via a well-maintained trail that begins near the Old Faithful Visitor Center. The trail is approximately 1.5 miles long and offers stunning views of other geothermal features along the way.
