Big Bend National Park
U.S. national park located in Southern Texas, bordering Mexico
Big Bend National Park is a national park of the United States located in West Texas, bordering Mexico. The park has national significance as the largest protected area of Chihuahuan Desert topography and ecology in the United States, and was named after a large bend in the Rio Grande/Río Bravo. The park protects more than 1,200 species of plants, more than 450 species of birds, 56 species of reptiles, and 75 species of mammals.
The area has a rich cultural history, from archeological sites dating back nearly 10,000 years to more recent pioneers, ranchers, and miners. The Chisos Mountains are located in the park, and are the only mountain range in the United States to be fully contained within the boundary of a national park. Geological features in the park include sea fossils and dinosaur bones, as well as volcanic dikes.
The park encompasses 801,163 acres (1,251.8 sq mi; 3,242.2 km2), entirely within Brewster County. For more than 1,000 miles (1,600 km), the Rio Grande/Río Bravo forms the boundary between Mexico and the United States, and Big Bend National Park administers approximately 118 miles (190 km) along that boundary.
Because the Rio Grande serves as an international boundary, the park faces unusual constraints while administering and enforcing park rules, regulations, and policies. In accordance with the Treaty of Guadalupe Hidalgo, the park's territory extends only to the center of the deepest river channel as the river flowed in 1848.

Why this record matters
“Big Bend National Park” is worth following because a concise public description often conceals a longer documentary argument. Here, Bend, National and Park provides the most credible route into that argument.
The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Sep 24, 2026. The linked authority identifier is Q1427197. VIAF identifies the subject as 234644008. The Library of Congress control number is sh85013944. Authority coordinates are 29.250, -103.250. 2 of 6 selected statements include explicit references; 2 carry qualifiers and 0 use preferred rank. The first chronological checks are 1848.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
