Big Bend National Park

What's so Special about this place? Big Bend National Park encompasses more than 800,000 acres in southwest Texas. For more than 1,000 miles, the Rio Grande forms the international boundary between Mexico and the United States; Big Bend National Park administers approximately one-quarter of that boundary. Within the 118 twisting miles that also define the park’s southern boundary, the river’s southeasterly flow changes abruptly to the northeast and forms the “big bend” of the Rio Grande.

Because the Rio Grande serves as an international boundary, the park faces unusual constraints when administering and blooming pitaya cactus enforcing park rules, regulations, and policies. The park has jurisdiction only to the center of the deepest river channel; the rest of the river lies within the Republic of Mexico.

South of the border, people call the Rio Grande by its Spanish name, Rio Bravo del Norte. South of the river lie the Mexican states of Chihuahua and Coahuila and the new protected areas for flora and fauna, which are comprised of regions known as the Maderas del Carmen and the Cañon de Santa Elena.

Big Bend National Park has national significance as the largest protected area of Chihuahuan Desert topography and ecology in the United States. Few areas exceed the park’s value for the protection and study of geologic and paleontologic resources. Cretaceous and Tertiary fossil organisms exist in variety and abundance. Archeologists have discovered artifacts estimated to be 9,000 years old, and historic buildings and landscapes offer graphic illustration of life along the international border at the turn of the century.

The park exhibits dramatic contrasts; its climate may be characterized as one of extremes. Dry, hot late spring and early summer days often exceed 100 degrees in the lower elevations. Winters are normally mild throughout the park, but sub-freezing temperatures occasionally occur. Because of the range in altitude from approximately 1,800 feet along the river to 7,800 feet in the Chisos Mountains, a wide variation in available moisture and in temperature exists throughout the park. These variations contribute to an exceptional diversity in plant and animal habitats.

Mariscal CanyonThe 118 river miles that form the southern park boundary include the spectacular canyons of Santa Elena, Mariscal, and Boquillas. The Rio Grande, meandering through this portion of the Chihuahuan Desert, has cut deep canyons with nearly vertical walls through three uplifts comprised primarily of limestone. Throughout the open desert areas, the highly productive Rio Grande riparian zone includes various plant and animal species and significant cultural resources. The vegetative belt extends into the desert along creeks and arroyos.

Cultural resources in the park range from the Paleo-Indian period 10,500 years ago through the historic period represented by Native American groups, such as the Chisos, Mescalero Apache, and Comanche. More recently, Spanish, Mexican, and American settlers farmed, ranched, and mined in the area.

cemetary at Glenn SpringsThroughout the prehistoric period, humans found shelter and maintained open campsites throughout the park. The archeological record reveals an Archaic-period desert culture whose inhabitants developed a nomadic hunting and gathering lifestyle that remained virtually unchanged for several thousand years.

The historic cultural landscape centers upon various subsistence or commercial land uses. The riparian and tributary environments were used for subsistence and irrigation farming. Transportation networks, irrigation structures, simple domestic residences and outbuildings, and planed and terraced farm land lining the stream banks characterize these landscapes.

Big Bend National Park lies in south Brewster County, one of the most sparsely populated areas of the country. Brewster County consists of 6,204 square miles and has a population of approximately 13,000 people. Most of Juniper Canyon View the population resides in two towns: Marathon and Alpine, which lie 69 and 100 miles respectively to the north and northwest of park headquarters. The western gateway communities of Study Butte, Terlingua, and Lajitas have experienced growth in recent years but still lag behind Marathon and Alpine in terms of population.

Visitation to the Park has averaged 300,000 in recent years. The 1992 Visitor Services Project determined that most visitors were 41 years of age or older, and most came to the park in family groups. Visitors from foreign countries comprised 10 percent of the visitation with 48 percent of the international visitors coming from Germany. Americans came from Texas (65 percent) with smaller numbers from many other states. This home state visitation figure is much higher than in most other national parks. Similarly, the average length of stay, 3 days, was also considerably higher than in most other NPS areas.
