Yellowstone National Park is home to more than 10,000 hydrothermal features, and this week we are enjoying a wonderful hydrothermal front country hike found inside the park…join me along Fountain Paint Pot Trail.

Fountain Paint Pot Trail follows a half mile boardwalk loop located along Grand Loop Road within the Lower Geyser Basin. This area is unique in that it showcases all four types of hydrothermal features found inside the park, including geysers, hot springs, mud pots and fumaroles. In fact, a thermophile organism which revolutionized DNA processes (Thermus Aquaticus) was discovered here.

As you begin this loop you’ll first encounter the Bacterial Mats, which are home to heat-loving thermophiles that form streaks of orange and brown colors here. Many “bobby socks” trees are found along this trail…these lodgepole pine trees have white silicified trunks where silica has hardened the tree bases during periods of shifting thermal activity.

The trails muddy namesake, “Fountain Paint Pot,” is made up of clay minerals and silica particles. The colors here vary throughout the year, as does the thickness of these mudpots. In Spring they can appear thin and watery, but by late Summer the mud can be so thick that bubbles burst up to the trail railing.

Over a dozen named features are sprinkled along the path here, including Leather Pool, which boasts a beautiful dark surface, and Silex Spring, which is colored with piercing icy blue hues. Fountain Geyser has regular eruptions that last 25 minutes (or more) and shoot up to 50 ft high. Just behind it sits Morning Geyser, which just happens to be one of Yellowstone’s largest geysers…it seldom erupts, but when it does it can tower up to 200 ft high and 100 ft wide.

Clepsydra Geyser splashes up from several vents, and since the Hebgen Lake earthquake in 1959, it has erupted almost constantly. You also pass Red Spouter, Jelly Geyser & Jet Geyser before reaching the final stop on this trail, Celestine Pool, with deep dark blue colors.
