crowds, cold temperatures, and steaming geyser
basins. Skis, snowshoes, snowcoaches, and snowmobiles become the main modes of transportation
as roads close, rivers and lakes freeze, and winter
storms blanket the park with snow.
STAY ALERT IN THERMAL AREAS
Hydrothermal features are evidence of an amazing
fact: Yellowstone sits above a giant supervolcano. If
you travel the 50 miles (80 km) between Mammoth
Hot Springs and Old Faithful, you will see travertine
terraces, acidic thermal features at Norris Geyser
Basin, mudpots and fumaroles at Fountain Paint
Pot, plus beautiful hot springs at Biscuit and Black
Sand basins near Old Faithful.
Inside
• Stay on boardwalks and designated trails.
The ground is unstable in hydrothermal areas.
Use caution, as boardwalks are often covered
in snow and ice.
• Keep hands out. Water in geysers and hot
springs can severely burn you.
• Keep litter out of the pools. Protect
Yellowstone's hydrothermal features by
never throwing any objects into them.

Keep Wildlife Wild
Winter is a wonderful time to
view wildlife. All the large
mammals present when Yellowstone became a park in
1872 are here today: grizzly and
black bears, wolves, mountain
lions, elk, bison, pronghorn,
moose, and bighorn sheep.
• Wildlife are dangerous.
• Do not approach, encircle,
follow, or feed any animal.
• Bison, bears, and elk injure and kill people.
• Stay at least 100 yards (91 m) from bears and wolves.
• Stay 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 a safe distance.
• Do not stop on or block a road.
• Use pullouts; stay in your car to watch animals.
• Store food and trash securely. Backpacks and snowmobile
gear bags are not secure.
• Do not feed any animals, even birds and squirrels.

How Do Geysers Work?
T h e U pp e r G e y s e r B a s i n o f Y e l l o w s t o n e
National Park has the largest concentration of
geysers in the world. Geysers are hot springs with
narrow plumbing, usually near the surface. These
constrictions prevent water from circulating freely to
the surface where heat escapes into the air. The deepest circulating water can be even hotter than the surface boiling point of 199°F (93°C) at the elevation of
Old Faithful Geyser (7,349 ft / 2,240 m), for example.
Pressure on hydrothermal waters increases with
depth. Increased pressure exerted by the enormous
weight of overlying rock and water prevents the deep
water from boiling.
As hot water rises, the overlying pressure decreases,
and the water can boil to steam. Bubbling upward,
the steam expands as it nears the top of the water
column until the bubbles can no longer pass freely
through constrictions in the geyser’s plumbing. At a
critical point, the confined bubbles actually lift water
lying above and cause the geyser to splash or overflow. The loss of overlying water further decreases
pressure on the hot water below, and violent boiling
results. Tremendous amounts of steam force water
out of the vent, and the eruption begins.
During a geyser eruption, water is expelled faster
than it can enter the geyser's plumbing system, so the
heat and pressure gradually decrease. The eruption
stops when the water reservoir is exhausted or when
the system cools.

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 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.

the Northern Range in winter and tips for safely
capturing stunning photographs.

the terraces of Mammoth Hot Springs. Hot water
steams in the cold winter air while ice and snow
accentuate the beautiful shapes of these living
sculptures.
Four factors come together to create the terraces:
• Water
Rain and snow falling on the surrounding mountains
seeps deep into the earth.
• Heat
The water is then heated by underground volcanic
heat. The exact source of the heat is unknown! (Scientists have proposed two sources: the large magma
chamber underlying the heart of the park or a smaller source closer to Mammoth.)
• Fractures and fissures
A network of fractures and fissures (cracks) acts like
plumbing. The very hot underground water travels
through the cracks to reach the surface.
• Limestone
Limestone was deposited millions of years ago when
a vast sea covered the area. The hot water travels up
through the limestone via the fractures and fissures,
carrying high amounts of dissolved carbonate minerals. At the surface, carbon dioxide is released, and
carbonate minerals like calcite are deposited, forming
travertine, the chalky white rock of the terraces.
Fort Yellowstone
Stay On Boardwalks
and designated trails. Do not touch any thermal
features and keep all objects out of springs.
To avoid slips and falls, use caution on ice and snow.
EXPLORE BY FOOT
Boardwalks provide access to the lower area of
Mammoth Hot Springs.
EXPLORE BY SKIS OR SNOWSHOES
The Upper Terrace Loop Ski Trail can be
reached by personal vehicle via the Upper
Terrace parking area. This groomed 1.5 mile (2.4 km)
loop ranges from easy to more difficult due to a steep
downhill section if traveled to the right (counterclockwise) from the trailhead.
It is easiest if skied beginning to the left (clockwise).
A moderate climb leads to views of hot springs, terraces, the Mammoth Hot Springs Historic District,
and the surrounding mountains. At the top of the
climb, a trail veers off to the southwest, which connects with the Snow Pass Trail. The Terrace Loop
Trail descends past more hot springs before completing the circuit. Since snow is less deep than in the
mountains above, wintering elk and deer are occasionally seen.
Th e U n i t e d S t a t e s e s t a b l i s h e d
Yellowstone National Park in 1872. For the next
decade, the park was under threat. Poachers killed
animals. Souvenir hunters broke large pieces off of
the geysers and hot springs. Developers set up camps
for tourists. The park turned to the US Army for help.
In 1886, men from Company M, First US Cavalry,
Fort Custer, Montana Territory came to Yellowstone
under the command of Captain Moses Harris. They
began what would be 32 years of military presence.
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. Most buildings constructed during the Army era are still standing and
are currently used by the National Park Service as
park headquarters and employee housing.

North and Northeast entrances travel through
the Northern Range, the hub of wildlife in Yellowstone National Park. Occupying just ten percent of
the park, it is winter range for the biggest elk herd in
Yellowstone and is arguably the most carnivore-rich
area in North America.
Safe
Parking
It is also the only area of the park that can be
reached by automobile year-round, providing
incredible opportunities to observe wildlife in
winter—when they are often more active and easier
to spot—as well as view beautiful winter scenery.

Unsafe
Parking
Looking out over a Northern Range valley, you
could see bison, elk, pronghorn, mule deer, wolves,
and more all interacting with each other.
If you choose to venture out into this winter
wonderland, remember:
• Watch out for wildlife on or near roadways.
• Do not feed any wildlife, including small
mammals and birds.
• Check road and weather conditions locally or
online before you depart (see back page).
• Drive cautiously. The park speed limit is 45 mph
(72 kph) unless posted slower. Icy and wet road
conditions require extra attention and lower speeds.
• Don't rely on your cell phone. There is almost no
cell service once you leave the Mammoth area.

Stopping, parking, or standing in the road is dangerous. Snow plows have limited visibility. Stay
aware of traffic at all times.
Wolf (Canis lupus)
• Use pullouts to stop.
• Park with all four tires fully to the right of the
white line.
• When your vehicle is moving, keep doors closed
and arms, cameras, and children inside.
• Do not stop your vehicle in the road
or block traffic in any way.
• Do not stand in the road or block it with
tripods, chairs, or other objects.
• If wildlife are nearby, stay inside your vehicle.
Photograph Wildlife

in the world to view—and photograph—wildlife in
their natural habitat. Professional photographers
share these tips for capturing the best shots while
respecting and protecting park 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.
Widen Your Perspective
Try to capture the character of the environment
around wildlife, too. Habitat says a lot and will
increase your chances of capturing interactions
between a variety of animals.
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.
Work the "Golden Hours"
Animals are most active in the early morning and
late afternoon or evening. Luckily, these are also the
hours of the day with the most dramatic light.
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.
A winter photography group.
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.

challenging skiing and snowshoeing trails. Track is
set on a few trails, others may be groomed, and all
unplowed roads and trails are open to skiing and
snowshoeing.
Equipment rental is available in nearby communities. Ski shop services, including lessons, rentals,
and repairs, are available at the Bear Den Ski Shops at
Mammoth Hot Springs and Old Faithful Snow Lodge.
Brochures with general trail maps and descriptions
are at warming huts and ski shops. One-way or
round-trip skier shuttles may be offered to specific
trails in the park for a fee.
DRESS FOR SUCCESS
Even in Yellowstone's severe winter temperatures,
you can be comfortable and safe if you prevent chilling and overheating by wearing the right clothes.
• Wear several adjustable layers including wind
protection and insulated undergarments.
• Avoid clothes that are too tight. They restrict
circulation and increase the chance of frostbite.
• Do not wear cotton clothes of any kind, including
jeans, sweatshirts, underwear, or socks. They retain
moisture and put you at risk of hypothermia.

ETIQUET TE
• Do not walk on snowshoe or ski trails.
• Snowshoe parallel to the ski track.
• Yield to faster skiers or those going downhill.
• Detour around wildlife. Do not approach.

the rest of the year, in winter the park is a magical
place: steam and boiling water erupt from natural cauldrons in the park's ice-covered surface,
snow-dusted bison exhale vaporous breaths as they
lumber through drifts of white, foxes and coyotes
paw and pounce in their search for prey in the deep
snow, and gray wolves bay beneath the frozen moon.
WINTER ADAPTATIONS
Yellowstone in winter is also a place of vulnerability. Wildlife endure extremes of cold, wind, and the
absence of ready food. Park conditions in this most
severe of seasons become a matter of life and death.
To survive, plants and animals are forced to adapt.
Here are some adaptions you can mimic to more
comfortably and safely enjoy your winter visit:
• Deer, elk, and bison sometimes follow each other
through deep snow to save energy. When skiing
and snowshoeing through fresh snow, take turns
breaking trail.
• Mammals molt their fur in late spring to early summer. Incoming guard hairs are longer and protect
their underfur. Additional underfur grows each fall
and is made of short, thick, often wavy hairs designed
to trap air. A sebaceous (oil) gland, adjacent to each
hair canal, secretes oil to waterproof the fur. Mammals have muscular control of their fur, fluffing it up
to trap air when they are cold and sleeking it down to
remove air when they are warm. Wear multiple layers, including wind and waterproof outerwear, to
adjust to changing conditions.
• Snowshoe hares have large feet to spread their weight
over the snow. Martens and lynx grow additional fur
between their toes to give them effectively larger feet.
Increase the surface area of your feet with skis or
snowshoes.
Human-caused sounds that mask the natural soundscape are, to some extent, unavoidable in and near
developed areas. However, the potential for frequent
and pervasive high-decibel noise from oversnow
vehicles has made the winter soundscape an issue of
particular concern in Yellowstone.
Every now and then, turn off any engines or music.
Listen to the sounds of winter. What do you hear? How
do the sounds around you impact your experience?
CLIMATE CHANGE
WINTER SOUNDSC APES
Yellowstone's soundscape is the total of all the
sounds within the park, including those that can't
be heard by human ears. Some sounds are critical
for animals to locate a mate or food or to avoid predators. Others, such as those produced by weather,
water, and hydrothermal activity, may be a result
rather than a cause of ecological processes.
Human-caused sounds can mask the natural soundscape. The National Park Service's goal is to protect
or restore natural soundscapes where possible and to
minimize human-caused sounds while recognizing
that they are generally more appropriate in and near
developed areas.
In Yellowstone, scientists expect ecosystems to
change due to increased temperatures and changing
rain and snow patterns. Some observed and expected
effects of climate change include:
• Average temperatures are higher now than they were
50 years ago, especially during spring.
• Snowpack throughout the area is decreasing and
snow is melting faster in the spring. This could impact agriculture and municipal water supplies downstream.
• The alpine zone may shift higher, decreasing or eliminating species that live in this important habitat.
How might warmer temperatures affect the winter
scenes that surround you?
Surviving Winter's Edge
Bison a r e iconic a nim a ls of the A mer ica n
West and, with adult males weighing up to 2,000
pounds (900 kg), the largest land mammal in North
America. The herd is made up of cows, calves, and
some younger bulls. Mature bulls spend most of the
year alone or with other bulls, except during the rut
(mating season).
Bison are well-adapted to Yellowstone winters.
Their thick fur and layers of fat keep them insulated
in average low temperatures of -30°F (-34°C). Their
massive humps are made of muscles supported by
long vertebrae and are used like snowplows, swinging side to side to sweep away the snow and uncover
grasses and sedges underneath.
Despite these adaptations, bison (and other wildlife)
in winter have limited energy reserves. Help protect
bison and yourself by always staying at least 25
yards (23 m) away.
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
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.
