Devils Tower National Monument, Wyoming

DEVILS TOWER
NATIONAL MONUMENT
Wyoming

UNITED STATES DEPARTMENT OF THE INTERIOR, J. A. Krug, Secretary
NATIONAL PARK SERVICE, Newton B. Drury, Director

An 865-foot tower of rock, serving as evidence of volcanic activity that occurred many millions of years ago

Devils Tower National Monument has the distinction of being the first national monument to be created. It was established by proclamation of President Theodore Roosevelt in the year 1906 under authority of the so-called Antiquities Act.

The great natural feature, Devils Tower (known to the Sioux Indian as MATEO TEPEE, meaning Grizzly Bears’ Lodge), is like a huge fluted monumental shaft set upon a mound, alongside the Belle Fourche River and amidst rolling grasslands and pine forests.

The Tower rises to a height of 1,280 feet from the river bed and some 865 feet from its apparent base on the hilltop. The diameter at its base is approximately 1,000 feet, and at the top averages 275 feet. The top surface embraces about an acre and a half, upon which mosses, ferns, grasses, shrubs, and sagebrush grow. Mice, pack rats, and chipmunks have been seen there, and the falcon and hawk make it their home. As viewed from various angles, the Tower has many shapes.

The fresh rock is of a dark grey color which, after weathering, bleaches to a light grey with tinges of buff. Lichens of various colors and shades grow on its face, reflecting tones of light, so that in color its appearance may change several times during the day, depending on conditions of atmosphere and light. On occasion, a red sunset may give it a reddish glow, fading to dull purple.

A Geologic Mystery

As to the mode of origin of the Devils Tower geologists are by no means in agreement. That the rock of the Tower was at one time molten and was forced upward from deep within the earth is no question, and that it cooled beneath the surface is probable. But whether the great shaft as it now stands is in reality hardened lava in the neck of an old volcano the enclosing walls of which have been removed by erosion, or whether it is part of a great sheet or sill of molten rock which was injected between rock layers, cannot be positively stated.

On the basis of either explanation hundreds of feet of rock have obviously been removed by erosion from around the Tower and carried by rivers toward the sea.

The columns present an interesting problem. They appear to have been produced in the rapidly cooling volcanic rock by regularly arranged cracks which were due to contraction of the cooling mass. The fact that they are not well developed in the base of the Tower may be due to the slower cooling of the more deeply buried part. The flare of the columns is a subject too involved for this brief account.

As to the age of the Tower it is believed to 2 have been formed early in the Age of Mammals, perhaps 50 million years ago, but to have been uncovered by erosion only in the last one or two million years.

Plant and Animal Life

About a half mile from the entrance to Devils Tower National Monument the visitor finds himself driving through a thriving prairie dog “town.” These animals were as typical of the original West as the buffalo. Their presence in towns covering several square miles was incompatible with agriculture, and the elimination of the species has progressed to the point where they are now rarely found. Since all forms of plant and animal life are protected within national monuments, this colony of prairie dogs gives one a glimpse of the Old West.

Mule deer may be seen occasionally, and also many small animals including cottontails and chipmunks.

A wide diversity of weather conditions, soil, and elevation, and the location of the monument between the mountains and plains, produce an interesting and extensive fauna and flora. These factors, together with interesting geological problems, afford the student of natural history a wealth of observation and information if he will but take the time to follow not only the trail which encircles the Devils Tower proper but the 4½ miles of nature trail as well.

The Monument Museum

Many questions come to those who view Devils Tower, and an effort is made to answer them through exhibits in the museum at the parking area. There, by use of pictures, diagrams, artifacts, and specimens, is presented an explanation of some of the features of the Tower, its geology, setting, history, and legend. These exhibits, of interest to the layman and student alike, are a logical prelude to a walk along the trails.

Location and Facilities

Located a little west of the center of Crook County, which lies in the northeast corner of Wyoming, the monument entrance is 7 miles northward from U. S. Highway 14, 29 miles northwest of Sundance, Wyo., and 33 miles northeast of Moorcroft, Wyo.

In the days gone by, because of its inspiring setting, the area close to the Tower was a favorite camping and picnicking site, first by the Indian and then by the pioneer who braved the rugged and traillike access to the very base of the great rock. Not the least inviting feature was the large spring of unusually pure and cold water located but a few feet from the base of the Tower, as if flowing from it.

In the development of the area, to afford easy access and more comfort for the hurried vacationist and thoroughgoing student as well, these salient primitive features are preserved by making the water available at nearly all principal points and by the development of the natural picnic and campground areas within the shadows of the Tower. Adjacent to the area, as well as within a few miles of it, are tourist cabins for those wishing overnight lodging, but who are not equipped to camp.

Administration

Devils Tower National Monument, containing 1,194 acres of federally owned land, is one of the areas of the National Park System owned by the people of the United States and administered for them by the National Park Service. In these areas the scenery and the objects of historic, prehistoric, and scientific interest are carefully preserved and displayed for public enjoyment.

Inquiries regarding the monument should be addressed to the Superintendent, Devils Tower National Monument, Devils Tower, Wyo.

Section 2. Information about the Mission of Project Gutenberg-tm

Project Gutenberg-tm is synonymous with the free distribution of
electronic works in formats readable by the widest variety of
computers including obsolete, old, middle-aged and new computers. It
exists because of the efforts of hundreds of volunteers and donations
from people in all walks of life.

Volunteers and financial support to provide volunteers with the
assistance they need are critical to reaching Project Gutenberg-tm's
goals and ensuring that the Project Gutenberg-tm collection will
remain freely available for generations to come. In 2001, the Project
Gutenberg Literary Archive Foundation was created to provide a secure
and permanent future for Project Gutenberg-tm and future
generations. To learn more about the Project Gutenberg Literary
Archive Foundation and how your efforts and donations can help, see
Sections 3 and 4 and the Foundation information page at
www.gutenberg.org Section 3. Information about the Project Gutenberg
Literary Archive Foundation

The Project Gutenberg Literary Archive Foundation is a non profit
501(c)(3) educational corporation organized under the laws of the
state of Mississippi and granted tax exempt status by the Internal
Revenue Service. The Foundation's EIN or federal tax identification
number is 64-6221541. Contributions to the Project Gutenberg Literary
Archive Foundation are tax deductible to the full extent permitted by
U.S. federal laws and your state's laws.

The Foundation's principal office is in Fairbanks, Alaska, with the

Section 4. Information about Donations to the Project Gutenberg
Literary Archive Foundation

Project Gutenberg-tm depends upon and cannot survive without wide
spread public support and donations to carry out its mission of
increasing the number of public domain and licensed works that can be
freely distributed in machine readable form accessible by the widest
array of equipment including outdated equipment. Many small donations
($1 to $5,000) are particularly important to maintaining tax exempt
status with the IRS.

The Foundation is committed to complying with the laws regulating
charities and charitable donations in all 50 states of the United
States. Compliance requirements are not uniform and it takes a
considerable effort, much paperwork and many fees to meet and keep up
with these requirements. We do not solicit donations in locations
where we have not received written confirmation of compliance. To SEND
DONATIONS or determine the status of compliance for any particular
state visit www.gutenberg.org/donate

While we cannot and do not solicit contributions from states where we
have not met the solicitation requirements, we know of no prohibition
against accepting unsolicited donations from donors in such states who
approach us with offers to donate.

International donations are gratefully accepted, but we cannot make
any statements concerning tax treatment of donations received from
outside the United States. U.S. laws alone swamp our small staff.

Please check the Project Gutenberg Web pages for current donation
methods and addresses. Donations are accepted in a number of other
ways including checks, online payments and credit card donations. To
donate, please visit: www.gutenberg.org/donate

Section 5. General Information About Project Gutenberg-tm electronic works.

Professor Michael S. Hart was the originator of the Project
Gutenberg-tm concept of a library of electronic works that could be
freely shared with anyone. For forty years, he produced and
distributed Project Gutenberg-tm eBooks with only a loose network of
volunteer support.

Project Gutenberg-tm eBooks are often created from several printed
editions, all of which are confirmed as not protected by copyright in
the U.S. unless a copyright notice is included. Thus, we do not
necessarily keep eBooks in compliance with any particular paper
edition.

Most people start at our Web site which has the main PG search
facility: www.gutenberg.org

This Web site includes information about Project Gutenberg-tm,
including how to make donations to the Project Gutenberg Literary
Archive Foundation, how to help produce our new eBooks, and how to
subscribe to our email newsletter to hear about new eBooks.
