Series: Plant Community Monitoring in Northern Great Plains Network Parks
Plant communities are essential components of all major ecosystems. Plants are the ultimate source of food for other organisms and the main source of organic material in soil and water. They also influence climate and provide the scenery that park visitors enjoy. The NPS Northern Great Plains Network monitors the number, identity, and relative abundance of plant species, as well as their horizontal cover and vertical structure, to determine the health of park ecosystems.

Changing Patterns of Water Availability May Change Vegetation Composition in US National Parks
Across the US, changes in water availability are altering which plants grow where. These changes are evident at a broad scale. But not all areas experience the same climate in the same way, even within the boundaries of a single national park. A new dataset gives park managers a valuable tool for understanding why vegetation has changed and how it might change in the future under different climate-change scenarios.

Updated Species Database Will Help Boost Amphibian Conservation Across the National Park Service
To steward amphibians effectively, managers need basic information about which species live in parks. But species lists need constant maintenance to remain accurate. Due to recent efforts, the National Park Service now has an up-to-date amphibian species checklist for almost 300 parks. This information can serve as the basis for innumerable conservation efforts across the nation.

How Pollinator Inventories Can Inform Park Management Decisions
Pollinators play a crucial role in national park ecosystems and beyond. In the national parks, species inventories help managers know which pollinators are present, and in what abundance, to better understand the state of park ecosystems and make decisions about how to manage them. From 2024 to 2026, 17 parks across the country will be surveyed for bees and butterflies.

Welcome to Devils Tower National Monument!
Welcome to America’s first national
monument! Devils Tower is an
iconic formation, a monolith rising
above the surrounding countryside.
As you explore the monument
today, the Tower you see will
be remarkable, everlasting in its
powerful appearance. Yet depending
on the time of day and the weather,
the formation can look dramatically
di°erent. Often, it is yellow-green against a clear blue sky, but in
shadow the Tower is black and seems to stand a little taller. When
fog rolls in, it is shrouded in mist, only peeking out occasionally to
say hello. If you visit in the winter, the Tower will be covered in a
dusting of snow. And if you stay for the sunset, the sun’s rays will
turn its face orange, refecting the colors of the sky. In this way, the
formation is remarkably dynamic, appearing different as the day
progresses and the seasons change – if you come back, you may see
a di°erent Tower than the one you see today. But Devils Tower is
also timeless, changing only on a scale imperceptible to human eyes.
Things To Do

• See the stars (p. 5)
• Take beautiful photographs
• Listen to nature
Since people frst arrived at Devils Tower more than 10,000 years
ago, the monolith has remained essentially unchanged. The Tower
you are seeing today is the same formation that Theodore Roosevelt protected as the nation’s first national
monument in 1906, the same landmark that explorers and settlers used as they moved west across the country, and
the same stone monolith where Native Americans have gathered and prayed for thousands of years. The sense of
awe that the Tower gives us is truly timeless. As you explore the monument today, we invite you to refect on this
timelessness. What does Devils Tower mean to you? We hope that you will carry this meaning with you as you
continue to explore America’s public lands – so get out there and Find Your Park!
Parking at Devils Tower
During the summer, parking around the visitor center between
10 am and 3 pm is often limited. Consider parking in other
designated areas during these peak visitation hours. For vehicles
with trailers, long-vehicle parking spaces are available to unhook
your rig before heading up to the visitor center - fnd them on
the way to the picnic area.
The picnic area provides access to the Circle of Sacred Smoke
sculpture and the prairie dog town. You can also fnd parking at
Joyner Ridge trailhead (inaccessible to most RVs and other large
vehicles). From these areas, you can choose to hike to the visitor
center.

Stories of the Tower
The Geologic Story of Devils Tower
Devils Tower is a unique geologic formation that defes expectations and explanations. The formation of the Tower
has fascinated and inspired geologists and other casual passersby for hundreds of years.
Kiowa Oral History of the
Tower’s Creation
Geologists agree on a couple of main points on the origin of the Tower. They agree that the Tower is composed of
an igneous rock called phonolite porphyry. The Little Missouri Buttes, a formation to the northwest of the Tower
and made of the same rock, were probably formed from the same body of magma as the Tower only a few thousand
years earlier. Phonolite porphyry is relatively rare on the surface of the Earth and is only found in a few other places
worldwide. The Tower formed about 1.5 miles below the surface when
magma pushed up through sedimentary layers around 50 million years
ago. What geologists still debate is how that process took place and
whether or not the magma ever reached the land surface. Numerous
ideas have evolved since the frst geologic studies of the Tower in
the late 1800s. Today, there are four primary theories, but geologists
continue to search for more detailed explanations.
The following is a translation of a Kiowa story told in 1987. Included
in the novella First Encounters (available in the bookstore), it is one of
the stories compiled by historian Dick Stone.
Before the Kiowa came south they were camped on a stream in the
far north where there were a great many bears, many of them. One
day, seven little girls were playing at a distance from the village and
were chased by some bears. The girls ran toward the village and
the bears were just about to catch them when the girls jumped on a
low rock, about three feet high. One of the girls prayed to the rock,
“
