Castolon: A Meeting Place of Two Cultures (Teaching with Historic Places)

Landscape in Big Bend National Park

Set below the towering cliffs of the Sierra Ponce, Castolon is a small trading and farming community in far southwest Texas. While the muddy Rio Grande brings a constant supply of water to the area, the lack of steady rain makes the landscape harsh. White and yellow soils lie open to the southern sun, woody vegetation is sparse and stunted, and turkey vultures soar overhead. Yet Castolon offers more than nature: its history includes a mixing of the people along the United States-Mexico border.

The first inhabitants of this section of the Rio Grande flood plain were American Indians, who farmed and hunted. By 1900, the area began to attract American and Mexican farmers and ranchers interested in establishing homesteads and raising families. As the rest of the U.S. entered the industrial age, the section of West Texas along the Rio Grande remained a frontier society. The 1910 Mexican Revolution brought unrest and danger to people on both sides of the river, as bandits and raiders invaded the area. The U.S. Army responded by commissioning permanent and temporary camps along the Rio Grande. One such post was Camp Santa Helena, located in the southwest corner of today’s Big Bend National Park. Just after the Mexican Revolution ended, two men created a farming, ranching, and storekeeping partnership at Camp Santa Helena, now known as Castolon. They named their business La Harmonia Enterprises, a name they hoped would accurately reflect a continuing condition of the area--harmony between peoples.

About This Lesson

This lesson about frontier life in Texas is based on the National Register of Historic Places registration file, “Castolon Historic District” (with photographs), and other source materials about Castolon and ranching in the Big Bend region. It was written by Carol E. Sperling, former Supervisory Park Ranger at Big Bend National Park. TwHP is sponsored, in part, by the Cultural Resources Training Initiative and Parks as Classrooms programs of the National Park Service. This lesson is one in a series that brings the important stories of historic places into the classrooms across the country.

Where it fits into the curriculum

Topics: The lesson could be used in teaching units on westward expansion or United States geography. Students will practice skills of map reading, and analysis of photographs and primary documents.

Time period: Late 19th century to early 20th century

Setting the Stage

Keep two general concepts in mind as you begin your study of Castolon, a small trading and farming community in far southwest Texas. First, although international boundaries sometimes correspond to natural features we can see--the U.S.-Mexican boundary does follow part of the course of the Rio Grande--borders themselves are not a visible part of the landscape. They exist because humans have created that idea, and they can change over time.

Second, trends and new technology do not always appear in all places at the same time. For example, while many Americans were driving automobiles and having milk delivered each morning to their houses, people in West Texas still traveled largely by horse or horse-drawn wagon and depended on their gardens, fields, and livestock for most of their food.

West Texas is arid, sparsely vegetated, and shows a great deal of topographic variation. The buildings in the Castolon Historic District sit on a mesa about 1,900 feet above sea level and just above the flood plain of the Rio Grande. About two miles away from the La Harmonia Store, a line of huge limestone cliffs--the Sierra Ponce--fill the southern horizon. To the north lies a single, flat-topped peak called Cerro Castellan and, beyond that, the Chisos Mountains. Average rainfall in the Castolon area is about eight inches each year. The soil is colorful, and woody shrubs and grasses grow in occasional clumps. The Rio Grande, about one-half mile away, is a muddy river which many people could wade across most of the year. During flood periods, however, the river roars past and has even flooded the lower areas where people farmed and lived.

Determining the Facts

Reading 1: Settling the Big Bend

Until the late 1800s, few non-native families settled in the Big Bend territory. Comanches and Kiowa attacked passing travelers, and the Army could provide little protection. The region had few services such as churches and schools, and transportation was difficult.

By the 1880s, when railroads had been built and conflict between Native Americans and the United States declined, American cattlemen began to enter the area. Mexican families who had earlier left the Big Bend began to drift back; they tended small herds of goats and farmed small tracts of land near springs, along the narrow creek valleys, and along the Rio Grande. Some were United States citizens, but many had grown up south of the river in Mexico. Some owned property, but others did not obtain legal title to the lands they occupied. Later-arriving American ranchers leased the land but did not bother the "squatters," who provided fresh vegetables and necessary labor.

The discovery of cinnabar, the ore used to produce mercury, also spurred population growth. Towns around the mines, most of which were near Terlingua, grew to include more than 3,000 people. Other settlements developed at Santa Helena (now called Santa Elena), Coyote, Terlingua Abaja, and Molinar; these small communities lay near the river and provided vegetables and hay to the mining towns about 25 miles north.

The Mexican Revolution began in 1910. For the next 10 years, revolutionaries like Pancho Villa, and bandits who found the war a convenient excuse, attacked villages and ranches on both sides of the river, robbing settlers of property and sometimes their lives. In 1911, the U.S. Army began establishing camps and mounted patrols to protect remote settlements. The Castolon area welcomed a small detachment of troopers from the 5th, 6th, and 8th cavalries when it established Camp Santa Helena in 1916. The men lived in tents and the construction of a permanent post began in 1919. After the Mexican Revolution finally ended, the need for patrols declined, and by 1921 the U.S. Army had withdrawn.

About this time, Howard E. Perry began the Chisos Mining Company, one of the most famous enterprises in the Terlingua area. Perry also began a farming and ranching business with Wayne Cartledge, the son of his lawyer. They called their business "La Harmonia Company" in order to give an international flavor to the enterprise and to promote the idea of harmony between American and Mexican residents of the area. The Perry-Cartledge businesses along the lower Big Bend helped consolidate the local people into four related, but independent settlements or villages. One of these, Camp Santa Helena, soon thereafter came to be known as Castolon. Its residents included the Cartledge family, the La Harmonia Store manager and his wife, and a dozen or more Mexican and American families, all of whom were employed by the La Harmonia enterprises. Perry and Cartledge received permission from the Army to use the main barracks building at Castolon as a trading post.

During the early years of Castolon, local people more or less ignored the international boundary. American ranchers regularly hired cowboys who were Mexican citizens, and Americans often visited their neighbors across the river. La Harmonia Store became an important source of supplies for American and Mexican families throughout the area. Only after 1920 did the laws of the international border become more carefully enforced. Even today there is no staffed port of entry within 75 miles of Castolon, and Mexican citizens regularly cross the Rio Grande and shop at the Castolon Store (formerly La Harmonia Store), use the telephones, or contact Big Bend National Park rangers for emergency medical help.

Reading 2: Captain Lafferty's Report

On November 12, 1919, Acting Morale Officer Captain F. R. Lafferty, stationed at Lajitas, Texas, reported that the troops of his command were split into three detachments: Lajitas, Terlingua, and Santa Helena. He went on to say:

There is little opportunity for amusement for these men--there is nothing but a small Mexican settlement at Terlingua, and La Jitas [Lajitas] and nothing at all at Santa Helena. This station is located at a point over one hundred miles from the nearest railroad and the men rarely leave here except under exceptional circumstances.

A football team has been organized between the Infantry and Cavalry detachments here. An effort has been made to enthuse the Infantry in riding but they do not take kindly to the idea of riding.

A camp is being established in the Chisos Mountains about fifty miles from here where it is proposed to send detachments from time to time and allow them to hunt.

An effort has been made to get a moving picture here but none have been shown here for months. One method I have adopted to keep up the spirits of the men is to feed them in the best possible manner, a difficult problem under the present ration system and method of supply; and to have them change stations frequently.

The old non-commissioned officers seem to be contented here but the younger-- the recruits--seem to long for a change of environment occasionally.

Reading 3

Because Castolon was far from the kinds of activities many young soldiers would want for their free time, Colonel Hornbrook wrote a recruiting broadside that he hoped would entice men to enlist. It was printed in February 1920.


Red Blooded Men Take Notice!

Do you ever long for the great outdoors?

Does the silent appeal of Nature, as exemplified by rugged mountains, deep canyons, rocky precipices, all equally inspiring get you?

Does being in a vast and undeveloped section, 100 miles from the railroad, strike a sympathetic note in your heart?

Does the idea of patrolling this historic and history making country where every man is on his own, make your pulse beat a bit faster?

Would you like to be in one of the wildest, least explored sections and the only real frontier of the greatest nation on earth?

Is there a man to whom hunting--and the best to be had in the United States at that--camping out for days and cooking your own meals under the bluest sky on earth, with the added zest that at any time the crack of a bandit's rifle may call you to the really serious business of being a solider, is there a real man I repeat, to whom these things do not appeal?

Join the Fifth Cavalry, hunting and fishing par excellence, deer and quail in abundance, rabbits by the thousands, with the added thought that at any moment the tables may be turned and you may be the hunter, hunted.

We get hunters in this district from Maine to California. The Government pays you to be here. This is an opportunity for any outdoors man who is a real sure nuff hunter and trapper who wants to see real untrammeled Nature at her best.

Join the Fifth Cavalry if you are for really honest-to-God outdoor life and next to nature stuff. We have it and are enjoying every minute of it, and we are calling to any man--and that is every man--whose heart and soul yearns for the riches we have, and who hasn't the necessary riches to enjoy them.

The Fifth Cavalry wants real men: men who like to rough it. We need you and you need us and our wonderful Big Bend District with all its vastness, all its wildness, and that added zest of danger that all he men desire. Sign up now while the spirit moves.

Questions for Reading 3
1) Which document, Captain Lafferty's report or Colonel Hornbrook's recruiting announcement, do you think painted a more accurate picture of life in small Army posts like Castolon? Why?
2) Describe three items in Colonel Hornbrook’s recruiting notice he hoped would attract men to enlist under his command. Would you have enlisted after reading this notice? (As it turned out, the Big Bend District which Hornbook commanded was disbanded a few months after this announcement was published.)
3) Why might Colonel Hornbrook have used these particular descriptions to enlist men?
4) Do you think this is a fair recruiting broadside? How might you try to enlist men if you were in the same situation?

Reading 4: A Frontier Border Trading Post

When Cartledge and Perry decided to go into the mercantile business in 1918, there had already been at least two small stores in operation in the Castolon area for nearly 20 years. By 1918, however, the rapid development of ranching, mining, and farming in the area had yielded a considerable increase in the population of the lower Big Bend. In addition, the store’s location adjacent to a vast region of the northern portions of two Mexican states, isolated from the interior of Mexico, gave it a large clientele from the northern part of Mexico.

La Harmonia Store sold not only merchandise, but also bought furs and candelilla wax, a natural wax derived from a desert plant. The business of dealing in hides, skins and furs continued at a lively pace until about 1940, when the dwindling supply from Mexico made it unprofitable. From 1920 to 1940, especially in the winter months, La Harmonia often looked like an old western fur trading post with hides, skins, and furs stacked in every possible nook and corner.

The management at La Harmonia soon learned to stock only those items which had a ready sale with the clientele of the border and the laborers on the farms and ranchers in the southern part of Brewster County. In addition, there was a limited demand from the occasional tourist for items such as blankets, glassware, pottery and other items. The majority of items on display for sale at La Harmonia were things needed by the people of the area. This is a partial list:

pocket knives karo [Karo] syrup shirts
barb wire sardines trousers
windmills prunes socks
plows raisins underwear
harnesses American cheese lace ribbon
saddles Salve ladies’ dresses
screwworm medicine Quinine capsules men’s suits (sometimes)
nails Ointment sugar
diarrhea pills bridal wreaths and veils coffee
toothache drops candies meal
liniments beer beans
patent medicines shoelaces salt
broad-brimmed hats toys crackers
shoes (mostly work shoes) miscellaneous furniture spices

Putting It All Together

The following activities allow students to compare what it was like to live in Castolon with life in their own communities during the same time period. They will also get some additional practice using Spanish.

Activity 1: Growing Up in Castolon
Ask students to write a 300 word essay describing the life they would have experienced if they were their current age and lived in the Castolon area during frontier times. Ask them to take into account the following questions:
1. What language or languages would you have spoken at home? Would everyone in the neighborhood have spoken the same language?
2. How would your family have made a living?
3. How often would you have travelled to a big city?
4. What would have happened when somebody got sick? Who would the family have called to help cure the sick person?
5. If you had the choice of crossing the Rio Grande in a rowboat and walking half a mile to La Harmonia Store, or doing without sugar, salt and flour, what would you have done?

Activity 2: Learning Some Spanish
Please note: this activity is intended for classrooms where few or no students know Spanish!

Have the students use a Spanish/English dictionary to define the following words: cerro, sierra, harina, leche, azucar, sal, vestido, maiz, pantalon, caballo, caballero, queso, casa, rio, camisa, zapatos, sombrero. Then hold an old-fashioned spelling bee--with a twist. Divide the class into two equal groups (if class numbers are unequal, appoint one student as assistant judge whose duty is to keep a running tally of correctly spelled and correctly used words). Have groups line up in two rows and then, alternating sides, give each student an opportunity to state the correct Spanish word when you call out the English equivalent. If there are more students than words, go through the process again, this time calling out the words in Spanish, with the students responding with the English version.

Activity 3: Comparing Castolon to the Local Community
Have students research what was happening in their own community from 1920 to 1940. Have them investigate:
1. How the population changed between 1920 and 1940;
2. Whether there were railroads, paved roads, and electric lights, and if so, when;
3. What public schools, hospitals, and libraries existed;
4. What kinds of work people did to make a living;
5. Whether the community was ethnically or racially mixed, and the dominant languages spoken;
6. What effects the Roaring Twenties and the Great Depression had; and
7. What the city looked like--what types of buildings, what building materials, how large, what ornamentation, etc.

When research is completed, have the students prepare a tabloid-sized newspaper which provides a description of the community from 1920 to 1940. Then ask students to draw a timeline showing the comparison of their community and Castolon.
