Yellowstone National Park, United States

The Greater Yellowstone Ecosystem’s wild, untamed, and pounding heart is Yellowstone National Park. The geysers and hot springs, which are nature’s crowd-pleasers and the real show stoppers, are everywhere you look, and they belch, breathe, and bubble like a huge kettle on the stove. These geysers are located along the park’s routes, which also pass through meadows, woodlands, bison herds, and campsites that are scented with pine needles and family campfires. Between them are the largest elk herd in the nation, the oldest and largest wild bison herds on the continent, and a pristine wilderness where wolves, grizzlies, moose, and antelope freely wander.

Grand Prismatic Spring

Grand Prismatic Spring is the largest and deepest hot spring in the park, measuring 370 feet wide and 121 feet deep. Many people also believe it to be the park’s most stunning thermal feature. Boardwalks encircle the stunning pool’s rainbow-colored algal rings and multicoloured algae mist. The spring appears to be a gigantic blue eye spilling gorgeous rainbow tears when viewed from above.

The spring empties into Excelsior Pool, a sizable extinct geyser that blew itself out in the 1880s with enormous 300-foot water blasts. The last eruptions at this location occurred in 1985, when the pool almost continually erupted for 46 hours before falling back asleep. According to T Scott Bryan’s The Geysers of Yellowstone, the pool continuously emits an astounding 4000 gallons of boiling water per minute into the Firehole River, which is enough to fill 300,000 car gas tanks each day. Here, a day’s worth of water is released, compared to two months’ worth of water released by Old Faithful. As you approach the basin over the bridge, you may observe the yellow and orange runoff.

After finding parking, spend 30 minutes visiting the features, which are connected by a boardwalk that is 0.5 miles long.

Drive to the Fairy Falls trailhead in the south and hike for one mile to the brand-new overlook platform on the mountainside for the most stunning images of Grand Prismatic Spring.

Mammoth Hot Springs

The focal point of the Mammoth area is Mammoth Hot Springs’ impressive Lower and Upper Terraces. Boardwalks that stretch for an hour wind amid elaborate and beautiful limestone ponds, ledges, and plateaus. The most picturesque locations are Palette Springs (accessible from the lower parking lot) and the sulfur-yellow Canary Springs (reached from the upper loop, 1 km south), although thermal activity is continuously changing, so consult the visitor centre for the most up-to-date information.  

The lower terraces of Minerva Spring are known for their intricate travertine formations, which have dried over time due to earthquake activity but are still among the most gorgeous in the region. Right now, the terraces at nearby Mound Spring have the most lovely hues and abstract designs. Because of how strange the scenery appears, it served as the planet Vulcan’s pre-CGI backdrop during the 1979 Star Trek movie’s filming.  

Over a tonne of travertine rises to the surface each year, and the terraces are made of dissolved underground limestone that is continuously deposited when the spring waters cool upon contact with the air. The many bacteria and algae that thrive in the warm waters are the cause of the yellow, orange, and brown discharge off the naturally white terraces.  

At the bottom of the terraces, by the parking area, is the phallic, dormant 36ft-high hot-spring cone called Liberty Cap apparently named after the hat style worn during the French Revolution. The former hot spring must have had particularly high water pressure to create such a tall cone during its estimated 2500-year life span.  

Opal Spring is progressively encroaching on a century-old property built by Robert Reamer across the street (the architect of Old Faithful Inn and Roosevelt Arch). The spring or the architecture must be preserved, according to park strategists. Rocky Mountain elk in rutting season who occasionally linger on Opal Terrace in the fall make for interesting photo subjects.  

1 km uphill from Mammoth, a 1.5-mile, paved, one-way road circles counterclockwise around the Upper Terraces; vehicles greater than 25 feet must park on the main Grand Loop Rd. The viewpoint provides access to Canary Springs and New Blue Spring as well as commanding views of the Lower Terraces and Fort Yellowstone. The sponge-like Orange Spring Mound and the aptly called White Elephant Back Terrace are highlights further around the road loop. Close to the huge Angel Terrace, the loop returns to the main road. Every day at 9:00 am, rangers offer a 90-minute tour of the Upper Terraces.

Take the unmarked Howard Eaton Trail from Orange Spring Mound to the lower Mammoth Terraces for a personal viewpoint. Start from the unmarked Snow Pass trailhead pullout, which is two minutes’ driving south of the Upper Terraces, for the best results.

Old Faithful

Old Faithful is the face of Yellowstone and a reliable crowd-pleaser, despite not being the tallest or even the most predictable geyser in the park. The geyser spews about 8000 gallons (150 bathtubs) of water up to 180 feet in the air approximately every 90 minutes. The geyser-side chairs, the upper-floor balcony of the Old Faithful Inn, and (highly recommended) from a distance on Observation Hill are all great vantage points from which to observe the eruption.  

The geyser regularly erupted roughly every hour for over 75 years, which is one of the reasons the Washburn expedition named it in 1870. The interval between concerts has previously ranged from 45 to 110 minutes, but it is now 90 minutes and becoming longer. An eruption typically lasts four minutes. Normal water and steam temperatures are 204°F (95°C) and 350°F (176°C), respectively. The recuperation period increases with the duration of the eruption. About 90% of the time, rangers can accurately forecast eruptions to within 10 minutes. Old Faithful hasn’t erupted on the hour, either.  

Counting the number of tourists sat around the geyser is a pretty accurate way to determine when an Old Faithful eruption is about to occur; the number of tourists is inversely proportionate to the amount of time until the next explosion.

You are sitting on a boardwalk built out of about three million recycled plastic water jugs if you find yourself fidgeting while you wait for the old salt.

Upper Geyser Basin

Although Old Faithful receives most of the attention, Upper Geyser Basin, which boasts Yellowstone’s densest concentration of geysers, is a fascinating place to explore. Both the flamboyant Anemone and the erratic Beehive Geysers can be seen on Geyser Hill. Keep watching for a spectacular display if you spot a group of Geyser Gazers clustered close to the latter while carrying backpacks and radios. The view from Daisy Geyser is amazing, and below you can see fantastic Castle Geyser, one of the biggest formations of its sort in the world.

Before choosing a hike, check the tourist center’s list of geysers with expected eruption times. Here, you could easily pass an entire day.

Porcelain Basin

The hottest exposed basin in the park, Porcelain Basin, is surrounded by a mile-long boardwalk loop. (The milky sinter deposits in the area, also known as geyserit, are where the term originates.) The ash-white ground literally pulses in some spots, and the bleached basin bubbles and boils like some enormous laboratory experiment. Check out the vistas from Porcelain Terrace Overlook, which is close to the Norris Museum. According to Rudyard Kipling, these sights gave the impression that “the tide of desolation had gone out.”  

As you leave the museum, turn left just before the reputedly hottest fumarole in the park, Black Growler Steam Vent, which is always blowing. This vent lacks a consistent water supply because, like the majority of fumaroles, it is higher than the floor of the basin. The sizable but dormant Ledge Geyser is down below.

The boardwalk turns left as it travels counterclockwise, passing Crackling Lake, a lake that bubbles like a deep-fat fryer, and the Whale’s Mouth, a gaping, blue hot spring.  

Whirligig Geyser and nearby Pinwheel Geyser’s turbulent waters started to become significantly more acidic in 2000, which helped the green cyanidium algae and yellow cyanobacteria that produce many of the spectacular colours in its drainage channels thrive. From extremely hot blues and whites (up to 199°F, or 92°C) to cooler yellows and greens (144°F, or 62°C), and even cooler beige and dark browns (130°F to 80°F, or 54°C to 26°C), the hue of these bacterial mats reveals the relative temperatures of the water. The nearby Constant Geyser used to erupt around every 20 minutes, but in recent years it has erupted much less regularly.  

Congress Pool, which first formed in 1891, the year that scientists gathered in Yellowstone for a geology congress, is accessible by a side path after Hurricane Vent. The portion of Porcelain Basin at the end of the boardwalk that changes the most quickly and is most active provides beautiful views of Mt. Holmes (10,336ft).

From here, a pathway by Nuphar Lake leads to Norris Campground.
