Norris Geyser Basin - Porcelain Basin: Some Like It Hot

This is a continuing series of posts on the world’s first National Park – Yellowstone. There are so many natural wonders found within its 2.2 million acres. Among its many popular destinations is the Norris Geyser Basin.

Norris is the hottest geyser basin in the Park. Most of the thermal features here have temperatures above the boiling point (around 200 degrees F). Scientists have drilled a hole 1,087 feet deep and measured temperatures as high as 459 degrees!

As I mentioned in my previous post, the Norris Geyser Basin is separated into two trails – the Back Basin and the Porcelain Basin. In this post, we will be touring the Porcelain Basin. The half-mile trail begins at the museum near the parking lot. The museum opened in 1930 to help Park visitors understand Yellowstone’s geologic history.

The Museum is the connector between the Back Basin and Porcelain Basin. Porcelain Basin was named in 1884 because of the milky white geyserite that covered most of the basin.

After we go through the Museum, the trail splits. The right path is a shorter loop trail leading to Congress Pool and Porcelain Springs. The trail to the left is the longer loop trail where most of the thermal features are located. We want to see the entire Porcelain Basin. So, we will be walking both loop trails (certain stretches are shared by both trails). The left trail begins with a hillside overlook of Porcelain Basin.

As the trail descends down the hillside, it passes Black Growler Steam Vent and Ledge Geyser. Ledge Geyser is the second largest geyser in the Norris Geyser Basin. While eruptions are rare, it has been known to shoot water 125 feet into the air. Steam can be seen from its vents. It was named in 1927 for its position under a ledge of geyserite.

Once again, the trail splits. The path to the right is part of the smaller loop trail. We will do that later. We follow the left trail (part of the longer loop trail). At this fork in the trail, we see Sunday Geyser. On a Sunday in 1964, “Milky Geyser” was born. Later, the name was changed to Sunday Geyser. It hasn’t been active since the early 1980’s.

Whirligig Geyser was named in 1904 because its water swirls in its crater during eruptions. This is one of the most colorful areas in the Porcelain Basin. The lime-green algae thrive in these warm acid waters while the orange cyanobacteria (bacteria that obtains their energy through photosynthesis) may be found in the runoff streams.

During our 2011 visit, Pinwheel Geyser could be seen from an observation platform at the north end of the boardwalk. However, in 2015, this platform was removed and a new boardwalk trail was built farther away from Pinwheel Geyser.

For a short distance, a dirt trail leads us along the edge of a forest.

We cross the East Fork of Tantalus Creek.

In 1967, Crackling Lake (formerly known as Spring #39) was named because of the popping sounds from nearby springs on its southern shore.

At this point, the longer loop trail returns to the Porcelain Basin Overlook.

Now, it’s time to hike the shorter loop trail. At the beginning of the trail (near the Museum), we head down the path on the right. It takes us to Congress Pool. It was named in 1891 to recognize the Fifth International Geological Congress in Yellowstone.

We continue walking until we reach an intersection. We follow the short spur trail leading to Porcelain Springs. Porcelain Springs is a great example of how siliceous sinter (geyserite) works to change the landscape. The ground is thin and new springs can break through this fragile environment while old vents can be quickly sealed over by the new mineral deposits.

Back on the main trail, we circle around the Basin and find Colloidal Pool. It’s a cluster of two or three bluish-colored hot springs located east of Sunday Geyser.

We walk pass Sunday Geyser and follow the trail back to the Porcelain Basin Overlook.

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.
