Safety and Regulations 

Watch Wildlife Safely 

Yellowstone ofers wildlife watching opportunities 

that are unparalleled in the lower 48 states. All the 

large mammals present when Yellowstone became a 

park are here today: grizzly and black bears, wolves, 

mountain lions, elk, bison, pronghorn, moose, and 

bighorn sheep. You might also see a variety of birds, 

including bald eagles. 

Looking for Wildlife? 

• To conserve energy, most wildlife are active in the 

cool of dawn or dusk. 

• Animals are everywhere in the park, but it is easier to 

see them in open meadows and sagebrush than in 

dense forest. 

• Find a place with a broad view for your binoculars or 

spotting scope, and be prepared to wait. 

Protect Yourself and the Animals. Obey Park Rules. 

• Stay at least 100 yards (91 m) from bears and 

wolves and at least 25 yards (23 m) from all other 

animals, including bison and elk. 

• If an animal moves closer to you, move away 

to maintain the appropriate distance. 

• Do not surround, crowd, or disrupt any animal's 

path of movement. 

• If other visitors put you or wildlife in danger, leave 

the area and notify a park ranger. 

• Spotlighting—viewing animals with artifcial light— 

is illegal. 

• Calling to attract wildlife is illegal. You may not bugle 

to elk, howl at wolves, or make bird calls of any kind. 

• Tracking wildlife with electronic equipment is not 

permitted. 

Store Food Securely 

Do not feed any wildlife, including small mammals 

and birds. Eating human food is unhealthy and encourages aggressive behavior. 

All food, trash, and scented items must be kept inaccessible to bears at all times. Tents, truck beds, and 

picnic tables are not secure. In some areas, ravens 

have learned to unzip packs and scatter the contents. 

None of these items, even if clean and empty, may 

be left unattended at any time: 

• Water and beverage • Food, including condiments, 

containers even if in containers 

• Cooking or eating utensils • Cosmetics and toiletries 

• Stoves and grills • Pet food and bowls 

• Coolers and ice chests • Pails, buckets, wash basins 

• Garbage, bagged or not

Call 307-344-5387 to report or retrieve items lost in lodging 

facilities. In other parts of the park, call 307-344-2109 or look 

online: go.nps.gov/lost-and-found. 

Firearms 

Firearms are allowed in national parks pursuant to state 

and federal regulations. They are prohibited in facilities where 

signs are posted, such as visitor centers, government offces, and 

some concession operations. Discharge of frearms is prohibited. 

Possession and use of weapons, such as air guns, bows and arrows, spears, and slingshots, is also prohibited. Details are available at go.nps.gov/yell-laws. 

Pets 

Pets are not allowed on trails or boardwalks, in the backcountry, or in hydrothermal basins. Where allowed, pets must 

be leashed and remain within 100 feet (30.5 m) of a road or 

parking area. 

Do not leave a pet unattended, tied to an object, or without 

adequate food, water, shade, ventilation, or other basic needs. 

Owners must bag and dispose of pet waste. We recommend that 

someone in your group remain with your pet at all times to personally ensure their well being.

Things to Do 

Boating 

The boating season opens May 29 and closes 

November 7, 2021. All watercraft (motorized 

boats, non-motorized boats, and foat tubes) must 

have a permit and be inspected for aquatic invasive species by park staff. Any watercraft suspected 

of harboring AIS will be subject to a non-chemical 

decontamination treatment. 

Aquatic Invasive Species are nonnative plants and 

animals that can cause irreversible harm to the ecosystem. New Zealand mudsnails, whirling disease, 

and lake trout have already resulted in loss of native 

fsh or closure of some park areas. 

Watercraft users and anglers are asked to inspect 

all items that may come in contact with park waters, 

ensuring that they are clean, drained, and dry. 

Motorized boating is allowed on Lewis Lake and 

most of Yellowstone Lake. Only non-motorized boating is allowed on most other lakes. Only one river 

is open to non-motorized boating: the Lewis River 

channel between Lewis and Shoshone lakes. 

If you plan to boat in the park, familiarize yourself 

with Yellowstone National Park boating regulations 

and information about inspections and permits, 

available online at go.nps.gov/YELLboating. 

BOAT PERMIT AND AIS INSPECTION LOCATIONS 

Motorized and non-motorized watercraft 

(including angler foat tubes): 

• Bridge Bay Ranger Station 

• Grant Village Backcountry Ofce 

• Lewis Lake Ranger Station

Backcountry Camping 

Overnight backcountry camping is only allowed in 

designated sites and requires a permit. Detailed 

information on backcountry permits, fees, and 

advanced reservations is available online: 

go.nps.gov/YELLbackcountry. 

Permits are free prior to Memorial Day. 

From Memorial Day through September 10, 

a per-person, per-night fee applies: 

• Backpackers and boaters: $3 per person per night 

Group maximum $15 per night 

• Groups with stock animals: $5 per person per night 

For current trail conditions visit: 

go.nps.gov/YELLbackcountryreport. 

Riding the Yellowstone River Trail. 

Horses, Mules, and 

Other Stock Animals 

Traveling in the Yellowstone backcountry with horses, mules, or llamas is an exciting way to see the park. 

By their very nature, these large animals have the 

potential to leave great impacts on the land. 

Permits are required for both day rides and overnight trips. To get a permit and plan a safe, enjoyable, 

low-impact trip, contact a backcountry ofce or look 

online at go.nps.gov/YELLhorseride. 

• Trails typically open for stock use July 1. Some 

trails may open earlier or later depending on trail 

conditions. 

• Proof of a negative Coggins test is required. 

• Hay is prohibited in the backcountry, and weedfree hay restrictions are enforced in other areas. 

• Stock may not be left at trailheads or kept in 

front-country, drive-in campgrounds overnight. 

Fishing 

General fshing season opens May 29 and closes 

November 7, 2021. Some areas remain closed until 

June 15. Fishing permits are required in Yellowstone; state-issued fshing permits are not valid 

within the park. Anglers 16 years or older need a 

permit; younger children can fsh for free with a permitted adult. 

Fishing regulations in Yellowstone protect the 

unique values of the park ecosystem and conserve 

native fsh species. Copies of the complete park regulations are available wherever permits are sold and 

online at go.nps.gov/fsh. 

Possession limits and closures vary throughout the 

park. Anglers are responsible for knowing the regulations in the area they are fshing. Anglers are also 

responsible for knowing how to tell the diference 

between species. Native fsh must be released 

unharmed back into the water immediately. 

These include: 

• Arctic grayling 

• Cutthroat trout 

• Mountain whitefsh 

These tackle and gear restrictions apply: 

• Hooks must be barbless. 

• Tackle and lures must be non-toxic. Lead tackle 

is not allowed. 

• Bait is prohibited. 

• Felt-soled footwear is not permitted. 

Gardner River 

below Osprey Falls 

Swimming 

Park waters are swift and cold. 

• Swimming in hot springs or their runoff 

is prohibited. 

• Swimming in park rivers is not recommended. 

Currents can be dangerously strong and fast. 

• Swimming in Yellowstone lake is not recommended. 

Average lake temperature is approximately 41°F (5°C). 

Certain Boats Banned 

Boats with sealed internal water ballast 

tanks are temporarily banned in the park 

to minimize the risk of introducing aquatic 

invasive species.

Things to Do 

Day Hiking 

More than 1,000 miles of hiking trails 

wind through Yellowstone National 

Park. Whether you hike for half a mile 

or more than 10, the backcountry can 

be an escape from the crowds and a 

chance to get in touch with the wilderness that Yellowstone preserves. 

Find hikes using the free park app (see 

page 2) or at go.nps.gov/YELLdayhikes. 

go.nps.gov/YELLbackcountryreport 

has information on seasonal closures 

and trail conditions. Be prepared for 

wildlife encounters, hike in groups of 

three or more, and carry bear spray on 

all hikes. 

Hiking in Bear Country 

Hiking in bear habitat has inherent 

risks. You are likely to be safer if you 

stay on roads and ofcial trails, but your 

safety cannot be guaranteed. Federal 

regulations require you to stay at least 

100 yards (91 m) away from bears. 

Learn more: go.nps.gov/bearspray. 

Bear spray is available for 

purchase in Yellowstone 

where stores are open. 

Bear spray cannot be taken 

on airplanes or thrown in 

the trash. Canisters can be 

recycled in the park. Check 

locally or online for locations. 

Photography 

Yellowstone is one of the best places 

in the world to photograph wildlife. 

The Name of the Game is Patience 

To get the best shot, you will spend 

more time waiting and observing than 

taking photos. Look for patterns in 

animal behavior that can help you get 

a great shot. You may have to wait a 

while, so be ready. 

Know Your Camera's Limits 

A cell phone camera will not be able to 

capture the same resolution and detail 

as a more advanced standalone camera 

with large lenses. Good photography 

isn't about getting close to the animal 

for a close-up. It's about having the 

right equipment for the job. 

• BE ALERT FOR BEARS. 

• MAKE NOISE 

in areas with limited visibility. 

• CARRY BEAR SPRAY, 

one can with each adult, 

and know how to use it. 

• HIKE IN GROUPS 

of three or more people. 

• DO NOT RUN; 

back away slowly. 

Stay Safe Behind and in Front of the 

Camera 

An unusual vantage point can add drama to your image, but you don't want 

to add the drama of a hospital visit to 

your trip. Never sacrifce safety for a 

photograph. 

• Be Aware of Your Surroundings 

Stay behind fences and guard rails. 

Never turn your back on wild animals. 

• Keep Children Close to You at 

All Times 

Never try to pose them with wildlife. 

• Stay Out of the Road 

Do not stop your vehicle in the road 

or stand in the roadway. Do not block 

any portion of the road with tripods, 

chairs, or other objects. Do not block 

the free fow of trafc. 

Photographers in Lamar Valley Biking in the spring.

Bicycling 

Bicycling, including the use of e-bikes, 

is permitted on established public 

roads, parking areas, and designated 

routes. Bicycles are subject to the same 

trafc rules as automobiles and are prohibited on trails and boardwalks. 

Park roads are narrow and winding 

with few shoulders, so regulations 

require cyclists to ride single fle, and 

we strongly recommend wearing a 

helmet and high-visibility clothing. 

Smoking Is 

Prohibited 

in geyser basins, on trails and boardwalks, in buildings, or within 25 feet 

(7.6 m) of building entrances. 

Hiking the Beaver Ponds Trail. 

Road elevations range from 5,300 to 

8,860 ft (1,615 to 2,700 m), and services 

and facilities are far apart—typically 20 

to 30 miles (37 to 56 km). During April, 

May, and June, high snowbanks may 

make travel more dangerous. 

Find information on the park website 

at go.nps.gov/YELLbicycling. 

Take Only Pictures 

Removing or possessing natural 

or cultural resources (like wildfowers, 

antlers, rocks, and arrowheads) is strictly prohibited.

Things to Do 

Become a Junior Ranger 

If you're age 4 or older, you can become a Yellowstone Junior Ranger! This program is a way to introduce children—and those young at heart—to the 

natural wonders of the park as well as their own role 

in preserving these wonders for the future. 

Authorized Guides 

Many authorized guides and outftters are ready 

to show you the wonders of Yellowstone, and each 

has a unique approach. Make sure that your guide, 

tour company, or other commercial service is fully 

authorized by the park. Authorized providers are 

listed on the park website at go.nps.gov/YELLtours. 

Report unauthorized operators to a park ranger, or 

contact Concessions Management at 307–344–2271. 

Explore Park Heritage 

Opportunities to connect to the past are 

everywhere in Yellowstone. Visit Mammoth Hot 

Springs to walk the self-guiding trail around Fort 

Yellowstone, which chronicles the US Army's role in 

protecting the park. Other historic sites include the 

Norris Museum, Obsidian Clif, and the Old Faithful 

Inn and Historic District. 

The Heritage and Research Center (above) is located 

just beyond the North Entrance in Gardiner, Montana. This facility is home to Yellowstone's museum 

collection, archives, research library, archeology lab, 

and herbarium. Open by appointment only. 

Make the Most of Your Visit 

Yellowstone encompasses more than 2.2 million 

acres, most of it beyond the reach of roads. One could 

dedicate their entire life to experiencing the park and 

still never see it all. Here are suggestions for making the most of the time you do have. 

Tour early in the day to avoid crowds. 

Most people tour the park from 10 am to 6 pm. Wildlife are most active at sunrise and sunset; arriving 

before 8 am improves your chances of observing animals during their active periods. Park entrance gates 

are open 24 hours a day. 

Visit a hidden gem. 

Take a day hike, or stroll one of our historic walking 

tours at Fort Yellowstone or Old Faithful. Explore 

nearby national park units, national forests, state 

forests, and state parks. The region ofers a variety of 

public lands for recreation and enjoyment. 

Only one day here? 

• Drive to the Old Faithful area and walk around the 

Upper Geyser Basin. 

• Visit Old Faithful and one other hydrothermal area, 

like Norris, West Thumb, or Fountain Paint Pots. Follow boardwalks and maintained trails to witness hot 

springs, mudpots, fumaroles, and geysers. 

• Begin in Hayden or Lamar valleys to look for some of 

the park's large animals. Bring binoculars or a spotting scope, and enjoy animals from a safe distance. 

• For a break from the road, consider one or two moderate day hikes. Always carry rain gear, extra food 

and water, bear spray, and other emergency equipment when venturing into the backcountry. 

• Have a picnic. Unpack your basket at any of the 51 

picnic areas throughout the park.

Two or more days? 

• Explore one theme, such as geology, in depth. For 

example, visit Mammoth Hot Springs to see travertine formations and view the sedimentary layers of 

Mount Everts, then drive through terrain shaped by 

glaciers to the Tower-Roosevelt area. 

• Visit Yellowstone Lake, the largest high-elevation lake 

in the lower 48 states. Take in the spectacular views 

of West Thumb and the Absaroka Mountains from its 

shores. Explore the hot springs, mud pots, and geysers of West Thumb Geyser Basin. Hike one of the 

local trails, such as the Scenic Lake Overlook near 

West Thumb. 

• Slow down and try your hand at capturing the beauty 

of Yellowstone through journaling, painting, or simply observing.

Famously Hot Features Stay on Boardwalks 

and designated trails. Do not touch any thermal

features, and keep foreign objects out of springs. 

It can be windy, so cinch your hats, and secure your 

items. 

Yellowstone was established in 1872 as the 

world's frst national park primarily because of 

its unparalleled collection of geysers, hot springs, 

mudpots, and steam vents. 

Fumaroles, or steam vents, are the hottest hydrothermal features in the park. They are easier to see in cool 

weather. 

Geysers erupt with steaming hot water. Variations 

in each geyser's underground reservoir determine 

whether it is regular and predictable—like Daisy 

Geyser in the Upper Geyser Basin—or irregular like 

Steamboat Geyser in Norris Geyser Basin. 

Hot springs are the most common hydrothermal 

features in the park. They vary from frothing mochalike boiling water to clear and calm pools of tremendous depth. 

Mudpots are acidic features with a limited water 

supply. Their consistency and activity vary with the 

seasons and precipitation. 

Travertine terraces are found at Mammoth Hot 

Springs, where the interactions of water and limestone create chalk-white travertine. 

How Faithful is Old Faithful? 

Since its frst documentation in 1870, Old Faithful 

has been one of the more predictable geysers. 

Over time, the average interval between Old Faithful's eruptions has increased or decreased due to 

changes in its plumbing from ongoing processes and 

earthquakes. The Hebgen Lake Earthquake (1959) 

caused an increase in the time between eruptions. 

The average interval between eruptions at Old Faithful Geyser is 94 minutes ± 10 minutes, with intervals 

ranging from 54 to 114 minutes. 

How do geysers work? 

Geysers are hot springs with narrow spaces in 

their plumbing, usually near the surface. These 

constrictions prevent water from circulating freely 

to the surface where heat would escape. The deepest 

circulating water can be more than twice as hot as the 

surface boiling point of 199°F (93°C). The surrounding pressure also increases with depth, similar to the 

ocean. Increased pressure exerted by the enormous 

weight of the overlying rock and water prevents the 

water from boiling as it heats up. 

As the water rises, steam forms. Bubbling upward, 

steam expands as it nears the top of the water column until the bubbles are too large and numerous 

to pass freely through the constrictions. At a critical 

point, the confned bubbles actually lift the water 

above, causing the geyser to splash or overfow. This 

decreases pressure on the system, and violent boiling 

results. Tremendous amounts of steam force water 

out of the vent, and the eruption begins. 

Water is expelled faster than it can enter the geyser's 

plumbing system, and the heat and pressure gradually decrease. The eruption stops when the water reservoir is exhausted or when the system cools. 

Yellowstone's geyser basins contain fountain- and 

cone-type geysers. Fountain-type geysers shoot 

water in various directions from a pool of water. 

Cone-type geysers like Old Faithful erupt in a concentrated jet of water from inside a rock formation. 

Norris Geyser Basin 

Some Like It Hot 

Descendants of the frst life forms to evolve on 

Earth live in the extremely hot, sometimes acidic, 

habitats in and around hydrothermal features. The 

heat-loving microorganisms, called thermophiles, 

survive and thrive in Yellowstone's active volcanic 

environment. 

Nourished by energy and chemical building blocks 

available in the hot springs, the microbes build vividly-colored communities like those you see in the photo above. The colors vary depending on the types of 

microbes, the pH (acidity or alkalinity), temperature 

of the feature, and exposure to sunlight. 

Millions of individual microbes can connect into 

long strands called flaments. Some flaments tangle, 

forming mats. Flowing water brings other microbes, 

organic matter, and minerals that add to the mat. 

Mats can be thin as tissue paper or thick as lasagna. 

Because of their fragility, they must not be touched. 

Dozens of types of microbes from all three domains 

of life can exist in these mats, from Archea in the 

hottest, most acidic features to the more widespread 

Bacteria and Eukarya. 

Scientists continue to study the many mysteries of 

thermophiles and their extreme habitats in the living 

laboratories of Yellowstone's thermal areas and features.

Wild Lands and Wildlife 

Wolves in Yellowstone 

Yellowstone is the site of one of the most ambitious and controversial wildlife restoration projects in the world. Although wolves once roamed 

from the Arctic tundra to Mexico, loss of habitat 

and extermination programs led to their demise 

throughout most of the United States by the early 

1900s. In 1973, the US Fish and Wildlife Service 

listed the gray wolf (Canis lupus) as an endangered 

species and designated the Greater Yellowstone Ecosystem as one of three recovery areas. From 1995 to 

1997, 41 wild wolves were released in Yellowstone. 

Keep Wolves Wild 

If you see wolves on or near the roadway: 

1.Slow down and move to the side of the road 

farthest from the wolves. Continue slowly 

moving as the wolves pass by. 

2.Do not stop within 100 yards (91 m) of the 

wolves. If conditions force you to stop, 

continue slowly moving within 10–15 seconds. 

3.If a wolf begins moving toward you, 

leave the area immediately. 

Never feed a wild animal. Wolves that eat 

human food even once will try to get food again. 

These wolves then have to be lethally removed. 

If a wolf approaches closely, report the 

sighting to park rangers. 

Bringing Up Bear Cubs 

Both grizzly and black bear cubs are born in the 

deep winter months while their mother hibernates. 

In April and May, they begin to venture out with 

their mother as she digs for roots, insects, and squirrels. Cubs stay with their mother for two to three 

years before setting out on their own. 

Look for black bears along the edges of wooded 

areas in the Lamar and Hayden valleys or among the 

trees near Mammoth and Tower. Grizzly bears are 

usually seen in open areas. 

See page 6 for information about safely recreating 

in bear country. 

Signs of Change

go.nps.gov/wolves. longer growing season. Some observed and expected 

efects of climate change are: 

• Alpine habitats will decrease in area, negatively affecting species that depend on them. 

• The number and intensity of wildfres is expected 

to increase in Yellowstone and across the Western 

US, resulting in more area burned over time. This 

will have a big impact on vegetation and vulnerable 

buildings. 

• Mountain pine beetle infestations may increase, 

driven by milder winters and a longer season for 

more reproductive cycles, causing more mortality in 

certain forest types. 

• Hotter, drier summers will drive a decline in wetland areas, reducing essential habitat for frogs, salamanders, and many bird and insect species. 

• Grizzly bears may have fewer whitebark pine 

nuts, a nutritious, high-calorie food source the bears 

depend on as they prepare for winter hibernation. 

• Non-native, invasive plants, able to take advantage 

of early spring moisture and drier summers, are 

starting to out compete native vegetation within the 

park’s lower elevation grasslands. 

Bison or Buffalo? 

In North America, both "bison" and "buffalo" refer to 

the American bison (Bison bison). Generally, "buffalo" is 

used informally, while "bison" is preferred for formal or 

scientifc purposes. 

Early European explorers called this animal by many 

names. Historians believe that the term "buffalo" grew 

from the French word for beef, boeuf. 

Within the Herd 

Yellowstone is the only place in the United States 

where bison have lived continuously since prehistoric times. Bison here are special: they're America's 

largest bison population on public land that can still 

migrate and adapt to diseases and predators 

Bison mainly eat grasses and sedges and are 

well-suited to both prairies and forests. With adult 

males weighing up to 2,000 pounds (900 kg), the 

bison is the largest land mammal in North America. 

The herd is made up of cows, calves, and some 

younger bulls. During the rut in July and August, 

mature bulls display their dominance by bellowing, 

wallowing, and fghting with other bulls to earn the 

right to mate with receptive females. After 9 to 9.5 

months, calves are born in late April and May. Their 

orange fur makes them easy to see and has earned 

them the nickname "red dogs." 

Look for bison in open country along the Lamar, 

Yellowstone, Firehole, and Madison rivers.

The Upper Geyser Basin, home of Old Faithful, Not all services available 

hosts the greatest concentration of active geysers 

on Earth, providing ample evidence of the active 

volcano below your feet. 

Yellowstone Volcano's reservoir of partially molten 

rock (magma) is ~5 miles (8 km) below the surface 

here. This magma provides the frst ingredient needed to create the area's hydrothermal features: heat! 

Rain and snow provide the second ingredient: water, 

which percolates ~0.5 miles (0.8 km) through hot, 

fractured rocks heated by the underlying magma 

reservoir. These hot, fractured rocks provide the 

third ingredient: the mineral silica. The extremely 

hot water below dissolves silica in the rocks. As the 

superheated water works its way back to the surface, 

it carries this silica and deposits it when it cools at the 

surface. In fact, Old Faithful geyser is a mound of silica that is growing ever so slowly after every eruption. 

Old Faithful erupts more frequently than any of 

the other big geysers, although it is not the largest 

or most regular geyser in the park. During summer, 

rangers forecast eruption times for six major geysers. 

However, a geyser's pattern of eruptions may change 

at any time.

The Grand Canyon of the Yellowstone River 

illustrates the park's complex geologic history in 

dramatic colors and shapes. The Upper and Lower 

Falls of the Yellowstone River add to the grandeur of 

this unique natural treasure. 

This canyon formed when hydrothermal activity 

altered and weakened the bedrock, making the stone 

softer. The Yellowstone River eroded the weakened 

rocks to deepen and widen the canyon. 

The 308-foot (93 m) Lower Falls marks the point 

where the volcanic bedrock beneath the river changes from hard rock, resistant to erosion, to the hydrothermally altered rocks common downstream. The 

109-foot (33 m) Upper Falls marks a similar shift. 

The multi-hued layers of the canyon result from the 

hydrothermally-altered rhyolite and sediments. Look 

closely at dark orange, brown, and green areas near 

the river for still-active hydrothermal features. Their 

activity—and that of water, wind, and earthquakes— 

continue to sculpt the canyon today.

Yellowstone Lake, at 286 miles2

 (740 km2 ), is 

the largest high-elevation lake (above 7,000 ft 

/ 2,130 m) in North America. The only outlet, the 

Yellowstone River, is at Fishing Bridge. The lake is 

covered by ice from December to May or June. 

Powerful geologic processes shaped the shoreline 

of Yellowstone Lake, which overlies the edge of the 

Yellowstone Caldera. Glaciers carved and lava fows 

flled the central lake basin. 147,000 years ago, an 

explosive eruption left behind West Thumb basin. 

Many of the 1,000 to 3,000 yearly earthquakes in 

Yellowstone occur under the lake because of the 

movement of magmatic fuids below. These forces 

continue to reshape the lake's shoreline. 

Yellowstone Lake is also the site of one of the most 

extensive conservation eforts in the National Park 

Service. Park staf work to reduce the impact of invasive lake trout (Salvelinus namaycush) on the survival 

of the native population of cutthroat trout (Oncorhynchus clarkii bouvieri).

Mammoth Hot Springs terraces are like living 

sculptures, shaped by the volume of the water, slope 

of the ground, and objects in the water's path. Travertine builds up rapidly here and causes the features to 

change quickly and constantly. Some vents may clog 

completely, new vents may form, and old vents may 

reopen. Sometimes the water is concentrated in a few 

springs; other times, it spreads across many outlets. 

Water follows the path of least resistance, whether 

above- or underground. Scientists estimate that, at 

any given time, only about 10 percent of the water in 

the Mammoth Hot Springs system is on the surface. 

The features are always changing, but the overall 

activity of the entire area and the volume of water 

discharge remain relatively constant. Here, as in few 

other places on earth, rock forms before your eyes.

Fort Yellowstone 

For the decade after Yellowstone National Park was 

established in 1872, the park was under serious threat 

from those who would exploit, rather than protect, 

its resources. In 1886, the US Army stepped in to help. 

The buildings of Fort Yellowstone are a testament 

to the long history of our frst national park and of 

the important role the army played in preserving 

it for the future. They remind us that the resources 

we fnd within Yellowstone's boundaries are not only 

natural ones, but cultural as well. Our interactions 

with this wilderness continue to shape our idea 

of what a national park should be, just as they did 

during the days of Fort Yellowstone.

A Global Legacy 

Yellowstone National Park was designated a 

UNESCO World Heritage Site in 1978 because it 

protects signifcant geological phenomena and 

processes. It is also a unique manifestation of geothermal forces, natural beauty, and wild ecosystems 

where rare and endangered species can thrive. As 

one of the few remaining intact large ecosystems in 

the northern temperate zone, Yellowstone's ecological communities provide unparalleled opportunities 

for conservation, study, and enjoyment of large-scale 

wildland ecosystem processes.
