Welcome to Yellowstone National Park

Yellowstone is a special place, and very different from your home. Like any grand adventure, 

your Yellowstone journey will take you to impressive new locations and introduce you to new 

experiences. There are different risks here than you may have faced before. You are responsible 

for your own safety. 

We need your help to preserve the wildlife, natural features, and cultural treasures that bring so 

many visitors to Yellowstone. The park rules protect you and also protect the park. Follow the 

park rules for a safe and enjoyable visit. Please be a positive part of the Yellowstone experience. 

More guidance is described inside and online at www.nps.gov/yell/planyourvisit/rules.htm.

Yellowstone National Park is assisted in fulfilling our mission by our official non-profit partner, 

Yellowstone Forever. Proceeds from Yellowstone Forever educational bookstores, Institute, and

Follow @YellowstoneNPS

Store food securely

Do not feed any wildlife, 

including small mammals and 

birds. Consuming human food 

is unhealthy and encourages 

aggressive behavior that 

may require animals to be 

destroyed.

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 how 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 

containers

• Cooking or eating 

utensils

• Stoves and grills 

• Coolers and ice 

chests

• Garbage—bagged 

or not

• Food, including 

condiments, even if 

in containers

• Cosmetics and 

toiletries

• Pet food and bowls

• Pails, buckets, and 

wash basins

ö Watching wildlife

Watching wildlife in Yellowstone can be an 

amazing experience—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 may also see a variety of 

birds, including bald eagles. 

Looking for wildlife?

• To conserve energy, most animals 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.

For your safety, and the safety of the 

animals please obey park rules:

• Stay at least 100 yards (91m) away from 

bears and wolves, and at least 25 yards 

(23 m) away from all other wild animals. 

• If an animal moves closer to you, you must 

move to maintain the appropriate distance. 

• Do not surround, crowd, or disrupt an 

animal’s path of movement. 

• If other visitors put you or wildlife in danger, 

leave the area and notify a park ranger. 

• Spotlighting, or viewing animals with 

artificial 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.

100 yards (91 m)

25 yards (23 m)

Smoking is prohibited in geyser 

basins, on trails, in buildings, or 

within 25 feet (7.6 m) of entrances. ` 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.

> Fishing season

General fishing season opens May 25 and 

closes November 3, 2019. Some areas remain 

closed until July 15. Fishing permits are required 

in Yellowstone, state-issued fishing permits are 

not valid within the park. Anglers 16 years or 

older need a permit; younger children can fish 

for free with a permitted adult.

Fishing regulations in Yellowstone protect 

the unique values of the park ecosystem and 

conserve native fish species. Copies of the 

complete park regulations are available wherever permits are sold, and online at www.nps.

gov/yell/planyourvisit/fishing.htm

Possession limits and closures vary throughout 

the park. Anglers are responsible for knowing 

the regulations in the area they are fishing. 

Anglers are also responsible for knowing how 

to tell the difference between species. Native 

fish must be released unharmed back into the 

water immediately. These include:

• Arctic grayling

• cutthroat trout

• mountain whitefish

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.

á Swimming

Park waters are swift and cold

• Swimming in hot springs or their runoff 

channels 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 41o F (5o C).

] Boating

The boating season opens May 25 and closes 

November 3, 2019. All watercraft (motorized 

boats, non-motorized boats, and float tubes) 

must have a permit and be inspected for 

aquatic invasive species (AIS) 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 park ecosystem. New Zealand 

mudsnails, whirling disease, and lake trout 

have already resulted in loss of native fish and 

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 nonmotorized 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, please familiarize yourself with Yellowstone National Park 

Boating Regulations. Copies are available online 

www.nps.gov/yell/planyourvisit/boating.htm

and at backcountry offices. 

Boat permits & 

AIS inspection locations

Motorized & non-motorized boat 

permits & AIS inspections:

South Entrance Backcountry Office, Grant 

Village Backcountry Office, Bridge Bay Marina 

Ranger Station

Float tube only permits 

& AIS inspections:

Locations above, and also at Mammoth 

Backcounty Office, Canyon Backcountry 

Office, Old Faithful Backcountry Office, 

Northeast Entrance, Bechler Ranger Station

] 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.

ç Backcountry camping

Overnight backcountry camping is allowed in 

designated sites and requires a permit. Permits 

can be obtained up to two days before the 

start of your trip at any backcountry office. 

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.

Detailed information on backcountry permit 

fees and making advanced reservations is 

available online at www.nps.gov/yell/planyourvisit/backcountryhiking.htm

I 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 around them. Permits are 

required for both day rides and overnight trips. 

To obtain permits and plan a safe, enjoyable, 

low-impact trip, please contact a backcountry 

office or look online at www.nps.gov/yell/

planyourvisit/horseride.htm

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 weed-free hay restrictions are 

enforced in other areas.

Photography

Have reasonable expectations of your 

camera. A cell phone camera will not be able 

to capture the same resolution and detail as a 

more advanced camera with large lenses.

Arm yourself with patience. To get the best 

shot, you will spend more time waiting and 

observing than photographing. Look for 

patterns in animal behavior that can help you 

get a great shot. You may have to wait a while—

so be ready.

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 

sacrifice 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 flow of traffic.

* Bicycling

Bicycling is permitted 

on paved roads, 

parking areas, and 

designated routes. 

Bicycles are subject to 

the same traffic rules 

as automobiles and are 

prohibited on trails 

and boardwalks.

Park roads are narrow 

and winding with few shoulders. Therefore, 

regulations require cyclists to ride single file 

and we strongly recommend wearing a helmet 

and high-visibility clothing. 

Road elevations range from 5,300 to 8,860 feet 

(1,615 to 2,700 m), and services and facilities 

are far apart. During April, May, and June, high 

snowbanks may make travel more dangerous.

Find information on the park website or pick 

up the Bicycling in Yellowstone brochure at a 

visitor center or ranger station.

Ñ 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 ten, the 

backcountry can be an escape from the crowds 

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

Ask at any visitor center for brochures 

describing day hikes throughout the park. 

Remember to ask about any seasonal closures, 

trail conditions, or wildlife sightings when you 

plan your hike. Be prepared for wildlife 

encounters and carry bear spray on all hikes. 

' Be prepared for 

bear encounters

Hiking in bear habitat has inherent risks. You 

are likely to be safer if you stay on roads and 

official trails but your safety cannot be guaranteed. Federal regulations require you to stay 

at least 100 yards (91m) away from bears. 

Learn more about bears, safe bear viewing, 

and how to properly use bear spray at 

Experiencing Wildlife in Yellowstone, a free 

ranger program presented from Memorial Day 

to Labor Day at visitor centers throughout the 

park. See visitor centers for details. 

Most popular day hikes:

1. Mount Washburn, north of Canyon

2. Beaver Ponds, at Mammoth Hot Springs

3. Lone Star Geyser, near Old Faithful

4. Fairy Falls, north of Old Faithful

5. Storm Point, east of Fishing Bridge Bear spray rentals

or models, require permits. For more 

information call: 307-344-2722.

Make the Most of Your Visit

Yellowstone encompasses more than 2.2 

million acres, most of it beyond the reach of 

roads. One could take an entire lifetime to 

experience the park—and you would still never 

see it all. Here are some 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 10:00 am to 6:00 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. 

Visit a hidden gem: Take a day hike, or stroll 

one of our historic walking tours at Fort Yellowstone or Old Faithful historic districts. You 

could even explore nearby national park units, 

national forests, state forests, and state parks. 

The entire region offers an amazing variety of 

public lands for recreation and enjoyment. 

Only one day here?

8 See the most with one-day driving tours:

• Drive to the Old Faithful area and walk 

around the geyser basin; drive to the Canyon 

area—stop at several overlooks and walk 

along the rim.

• Or, visit Old Faithful and one other 

hydrothermal area, such as Norris, West 

Thumb, Fountain Paint Pots, or Mammoth.

• Begin in Hayden or Lamar valleys to look for 

some of the park’s large animals. For a break 

from the road, consider one or two moderate 

day hikes. 

• Explore one area of the park in depth—

attend a ranger talk. From 15-minute 

presentations to 2-hour tours, programs are 

available throughout the park. 

• Make plans to visit again soon!

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, 

drive through glaciated terrain to Tower 

Fall or the Lamar Valley, then climb Mount 

Washburn to view the Yellowstone Caldera 

and evidence of glaciers.

• Plan an overnight trip into Yellowstone’s 

backcountry. Rangers at park backcountry 

offices can help you find a site, get a permit, 

share information about trail conditions, and 

help make sure that you are equipped and 

informed for a safer experience.

• Slow down and try your hand at capturing 

the beauty of Yellowstone through 

journaling, painting, or simply observing.

Famously Hot Features

Yellowstone was established in 1872 as the 

world’s first national park primarily because 

of its unparalleled collection of geysers, hot 

springs, mudpots, and steam vents. 

Hot springs are the most common hydrothermal features in the park. They vary from 

frothing mocha-like 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. 

Fumaroles, or steam vents, are the hottest 

hydrothermal features in the park. They are 

easier to see in cool weather.

Travertine terraces are found at Mammoth 

Hot Springs, where the interactions of water 

and limestone create chalk-white travertine.

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. 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 confined 

bubbles actually lift the water above, causing 

the geyser to splash or overflow. 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-type geysers and cone-type geysers. 

Fountain-type geysers shoot water out in 

various directions from a pool of water. Conetype geysers, like Lone Star Geyser (photo 

above) erupt in a concentrated jet of water 

from inside a rock formation. 

The trail to Lone Star Geyser begins about 3.5 miles 

southeast of Old Faithful. The bubbling mudpots of Fountain Paint Pots may be 

thicker or more active as local precipitation changes.

How “faithful” is Old Faithful Geyser?

Since its first 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 of Old Faithful Geyser, as of February 2019, is 98 minutes ± 

10 minutes, with intervals ranging from 79 to 109 minutes.

Where geology and biology thrive

Descendants of the first 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 

that 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 filaments. Some filaments 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. Due to 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. 

Microorganisms thrive in hot springs, and other 

hydrothermal features.

ñ Stay on boardwalks and 

designated trails. Do not touch 

any thermal features and keep foreign 

objects out of springs.

Within the herd

Yellowstone is the only place in the United 

States where bison have lived continuously 

since prehistoric times. Yellowstone bison are 

special because they are America’s largest bison 

population on public land and have not been 

hybridized through interbreeding with cattle. 

Bison eat primarily grasses and sedges and 

are well-suited to both prairies and forests. 

With adult males weighing up to 2,000 pounds 

(907 kg), the bison is the largest land mammal 

in North America. This iconic ungulate is the 

National Mammal of the United States. 

Yellowstone bison herds exhibit wild behavior, 

like their ancient ancestors. The herd is 

comprised of cows, calves, and some younger 

bulls. Mature bulls spend most of the year 

alone or with other bulls—except during the 

rut, or mating season. During the rut in July 

and August, mature males display their dominance by bellowing, wallowing, and fighting 

with other bulls. The winners earn the right to 

mate with receptive females. 

After a gestation period of 9 to 9 1⁄2 months, 

calves are born in late April and May. Their 

orange fur makes them easy to see, even from 

a distance, and has earned them the nickname 

“red dogs.” Look for bison in open country 

along the Lamar, Yellowstone, Firehole, and 

Madison rivers. 

Signs of change

The National Park 

Service anticipates 

that climate change 

will create significant challenges to 

the preservation 

of park resources, 

infrastructure, and 

visitor experience. 

Within Yellowstone 

specifically, scientists 

expect ecosystems 

to change due to 

increased temperatures 

and changing rain and snow patterns. Some 

observed and expected effects of climate 

change are:

• The alpine zone may shift higher, decreasing 

or eliminating species that live in this 

important habitat.

• Wildland fire in the western states is 

expected to intensify. In Yellowstone, fires 

may be more frequent, but smaller and less 

intense.

• Increased insect or disease infestations in 

trees.

• Declining wetlands will decrease essential 

habitat for frogs, salamanders, and many 

birds and insects.

• Grizzly bears may have less of their most 

nutritious foods such as whitebark pine nuts 

and army cutworm moths.

• Native plants may be lost and replaced 

with nonnative invasive exotic plants more 

adapted to dryer conditions.

Bison or buffalo?

In North America, both “bison” and 

“buffalo” refer to the American bison 

(Bison bison). Generally, “buffalo” is used 

informally; “bison” is preferred for formal 

or scientific purposes. Early European 

explorers called this animal by many 

names. Historians believe that the term 

“buffalo” grew from the French word for 

beef, boeuf. American bison are a different 

genus than other buffalo in the world.

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 

striking 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.)

Pack mentality

Yellowstone National Park is the site of one 

of the most ambitious and controversial 

wildlife restoration projects in the world. The 

Yellowstone Wolf Project has yielded more than 

two decades of discoveries on wolf behavior, 

predator–prey relationships, wildlife disease 

management, and ecological complexity.

The stark white backdrop of snow and the 

general absence of leaf cover make winter an 

ideal time for visitors and researchers alike to 

observe wildlife. From the popular overlooks 

of Lamar Valley, it is possible to get a glimpse 

of wolf society. You may even witness the 

dangerous dance of predators and prey as each 

struggles to survive.

Members of the Lamar Valley pack in 2012.

Climate change poses a 

major threat to sensitive 

species like the American 

pika (Ochotona princeps).

A raven’s perspective on Old Faithful.

The Upper Geyser Basin, home of Old Faithful, 

hosts the majority of the world’s active geysers. 

The concentration of hydrothermal features 

here provides ample evidence of Yellowstone’s 

active volcano. 

Partially molten rock, or magma, from this 

volcano may be as close as 3–8 miles (5–13 

km) below your feet. Magma provides the first 

key ingredient for creating thermal features: 

heat. Rain and snow eventually supply the 

second ingredient: water. The water seeps 

down several thousand feet (more than a 

kilometer) below the surface where it is heated. 

Underground cracks and earthquake faults 

form the third ingredient: a natural “plumbing” 

system. Super-heated water rises through the 

plumbing to produce hot springs and geysers.

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. (Five are here; 

the sixth—Great Fountain—is in the Lower 

Geyser Basin north of Old Faithful.) However, 

a geyser’s pattern of eruptions may change at 

any time. 

 Forecasted eruption times are 

posted in the Visitor Education 

Center and in many of the area 

facilities. You can also call 

307-344-2751 (option 2), access 

predictions on the Yellowstone 

National Park app, or check the

Canyon Village and Grand Canyon of the Yellowstone River

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 is the largest high-elevation lake (above 7,000 ft) in North America, 

covering 286 square miles, with an average 

depth of 138 feet. The only outlet of the lake is 

at Fishing Bridge, where the Yellowstone River 

flows north. The lake is covered by ice from 

mid-December to May or June.

Powerful geologic processes shaped the shoreline of Yellowstone Lake, which overlies the 

edge of the Yellowstone caldera. Glacial activity 

and volcanic events carved the central basin 

and ragged shores. A pyroclastic explosion 

created the West Thumb basin 174,000 years 

ago. Many of the area’s 1,000 to 3,000 annual 

earthquakes occur under Yellowstone Lake, 

causing uplift and subsidence events which 

continue to reshape the water’s edge.

Yellowstone Lake is also the site of one of 

the most extensive conservation efforts in 

the National Park Service. Park staff 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

Mammoth Hot Springs terraces are like living 

sculptures, shaped by the volume of water, 

the 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 will clog completely, 

new vents may form, and old vents may 

reopen. Sometimes the water is concentrated 

in a few springs while at other times it may 

spread across many outlets. 

In every case, water follows the path of least 

resistance, whether above ground 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 

U.S. Army stepped in to help.

The buildings of Fort Yellowstone are a testament to the long history of our first national 

park and of the important role the Army 

played in preserving it for the future. They 

remind us that the resources we find 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 significant 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.
