Heart Spring is a small, deep pool, measuring approximately 7.5 feet (2.3 meters) by 10 feet (3 meters) at the surface and extending 15 feet (4.6 meters) deep. Its water is exceptionally hot, with an average temperature of 184.8°F (84.9°C).
The striking orange and yellow colors around Heart Spring are created by thermophiles, which are heat-loving microorganisms. These tiny organisms thrive in the extreme temperatures of the spring's outwash channels, forming colorful mats that are visible to the naked eye.
Yes, Heart Spring is an integral part of Yellowstone National Park's extensive hydrothermal system. This system is fueled by superheated water rising from deep underground, a process driven by the Yellowstone volcano, with molten rock potentially as close as 3-8 miles (5-13 km) beneath the surface.
The spring was named around 1959 by park geologist George Marler. It was reportedly given the name 'Heart Spring' due to its distinctive heart-like shape.
Due to the extremely high temperature of the water, visitors must always stay on the designated boardwalks and paths. This is crucial to prevent severe burns and to protect the delicate thermal features and microbial mats surrounding the spring.
Yes, Heart Spring is considered family-friendly. The terrain around the spring is generally flat and accessible via boardwalks, making it easy for visitors of all ages, including those with strollers, to observe the natural monument safely.
In Yellowstone National Park, pets are generally not allowed on boardwalks or trails. They must be restrained at all times and are only permitted in developed areas, such as roads, campgrounds, and parking lots. Service animals are an exception to these rules.
Heart Spring is located in the Upper Geyser Basin, near Old Faithful. Visitors typically access it via the well-maintained boardwalk system. Parking is available at the Old Faithful area, but it can fill up quickly, especially during peak season. Arriving early in the day is recommended.
Absolutely. Heart Spring is situated in the Upper Geyser Basin, which is home to a high concentration of Yellowstone's famous geysers and hot springs, including the iconic Old Faithful. The boardwalk system connects many of these features, allowing for easy exploration of the surrounding area.
While the immediate vicinity of the hot spring itself is too extreme for most large wildlife, the Upper Geyser Basin and surrounding Yellowstone National Park are rich in biodiversity. Visitors might spot bison, elk, deer, and various bird species in the broader area. Always maintain a safe distance from all wildlife.
Heart Spring is located near the Old Faithful area, which offers a range of visitor services. These include visitor centers, restrooms, dining options, gift shops, and lodging facilities, all within a short walking distance or drive.
