Yellowstone: Mammoth Hot Springs are Really Cool (Lower Terraces)

Yellowstone National Park has many special places but the travertine terraces found at Mammoth Hot Springs are one of my favorite areas in the Park. This post features the Lower Terraces and is a continuation from my previous post on the Upper Terraces. A boardwalk trail (about 1.75 miles with 300 feet of elevation change) goes around the Upper and Lower Terraces.

Mammoth Hot Springs is always changing and sometimes the change can occur overnight. That’s because the rapid build up of travertine can create obstacles for the water’s flow. Water takes the path of least resistance. That means a once dry and chalky-white terrace may spring to life in a colorful display while another terrace may become dry and dormant. Such is the exciting cycle at Mammoth Hot Springs.

To demonstrate this constant state of change, I am including some photos we took in 1989 as a comparison. Since our cameras weren’t as good in 1989, the photo quality reflects the camera quality.

We park the car at the largest parking area in front of the boardwalk trail to Minerva Terrace. From here, we walk the handicap accessible trail to see the iconic symbol of Mammoth - Liberty Cap. This 37’ tall extinct hot spring cone of travertine is estimated to be 2,500 years old. It was given its name in 1871 because of its resemblance to the conical caps (sometimes referred to as Liberty Caps) worn by the French revolutionary army as part of their uniform.

Opposite Liberty Cap, on the east side of the road, is Opal Terrace. It was named in 1871 by the Hayden expedition. It was probably named for its opalescent blue color. I’m not sure why but we have never stopped to go see it. A photo of it will have to wait for a future visit.

We walk back to the parking lot. From here, we climb the hillside stairs to continue our tour of the Lower Terraces. For no particular reason, we walk the loop trail around Minerva Terrace in a counter-clockwise direction.

In Roman mythology, Minerva was the goddess of artists and sculptors. It’s a fitting name for a place that is constantly being sculpted and shaped. During active periods, water cascades over a series of step-like travertine terraces creating a colorful hillside. During inactive periods, the travertine is exposed. When travertine is new, it is bright white in color. It turns gray as it ages and weathers.

On our right, we pass a lovely blue-colored pool called Palette Spring.

Nearby is another extinct travertine cone called Devil’s Thumb.

Along the “backside” of Minerva Terrace is Cleopatra Terrace (to our right). Unfortunately, we didn’t stop to photograph it during our last Yellowstone visit. I’m curious to see what it looks like today.

We arrive at an intersection to the boardwalk trail. A right turn would take us up the hillside to an overlook at the Upper Terraces. Since we have already been there, we turn left (back toward the parking lot).

In 2018, we didn't see a lot of color at Mammoth Hot Springs until we reached Mound Spring.  Here, we find a rainbow of pastel colors dripping down the limestotne ledges into a beautiful pool rimmed with white edging.

The trail to the parking lot takes us by Mound Terrace and Jupiter Terrace.

If Mound Terrace were in a cave, these icicle looking features would be called Cave Draperies.

Jupiter Terrace is attached to Mound Terrace. In 1871, the Hayden expedition named it for the Roman god Jupiter. During our 1980’s visit, Jupiter Terrace was active.

Here are my final thoughts about touring the terraces.   If it is sunny and warm, you need to know there aren’t any shade trees along the boardwalk trail.  It’s always a good idea to bring some water to drink but please pack out what you bring in.  Oh, and don’t forget your camera and an extra battery!

No matter how many times I visit Yellowstone, I never get tired of seeing its ever-changing scenery. I invite you to view my other blog posts on Yellowstone National Park by clicking on the following links:

Planning a visit to Yellowstone? Food and lodging options are available inside the park and in towns just outside the park (West Yellowstone, Gardiner, and Cooke City/Silver Gate – all located in Montana). I highly recommend making lodging reservations in advance. Yellowstone is a popular destination and “No Vacancy” signs are common especially during the peak summer months. Since opinions, preferences, and budgets vary, I suggest checking a trusted travel source for current reviews.

My best advice is this - don’t just drive through Yellowstone – experience it!

The National Park Service has created a series of short videos titled “Inside Yellowstone”. It’s a fast and fun way to learn about the Park. Click on the following link to begin this Yellowstone experience.
