Texas, also known as the Lone Star State, is the second largest state in the United States in terms of population and area. Located in the southernmost part of the central US, Texas is known for barbecue, hot weather, live music, American football, ranching, and a deep-rooted feeling of Texas pride.

Texas mountains

The state of Texas is home to 2164 named mountains, peaks, and hills. Guadalupe Peak (8,757ft/2,669m) is the highest point and Emory Peak (7,785ft/2,373m) is the most prominent point.


Texas is situated in the south-central part of the United States.It shares a border with four other states, including Louisiana and Arkansas to the east, Oklahoma to the north, and New Mexico to the west.

Moreover, Texas forms a significant portion of the United States’ land border with Mexico. Texas borders the states of Nuevo León, Coahuila, Tamaulipas, and Chihuahua in Mexico to the south and west, as well as the Gulf of Mexico to the southeast.

With an area of 268,569 square miles (695,662 sq. km), Texas is the second largest state in the US, after Alaska, taking up about 7% of the country’s entire land area. It is also the second largest state by population, with its 28.9 million residents second only to the 39.5 million inhabitants of California.

Texas, as a result of its size, is incredibly geographically diverse It can be broken up into various regions, each of which are dominated by unique terrain. According to the Texas Almanac, the state has 4 major physical regions, namely:

  • Basin and Range Province
  • Interior Lowlands
  • Gulf Coastal Plains
  • Great Plains

In many respects, Texas can be considered part of the “Deep South,” particularly in East Texas. However, Far West Texas is often thought of as part of the Interior Southwest while the Texas Panhandle, in many ways, is more similar to the Midwest than to the South.

Indeed, simply while traveling from east to west through Texas, the landscape changes drastically from forests and swamps into plains, hills, desert, and mountains. The geographic diversity of the state has also led to the informal creation of a number of different economic and cultural regions, each of which are inextricably linked to the landscape.


Texas covers a huge swath of land, so it’s not surprising that the state’s geology is complex and diverse.

A dominant feature of Texas is its fault lines. The state is bisected by a number of faults which separate a series of different geological sub-regions.

In the south and east, the surface rock is mostly sandstones and shales which are underlaid by large salt domes that contain significant amounts of oil. To the north and west, there are mostly shales and limestones. In fact, the limestones in Texas’ Hill Country contain the Edwards Aquifer, which supplies drinking water to some 2 million people.

Toward the center of the state, there is a large dome of ancient gneisses, granites, and schists, which is surrounded by a large outcropping of sedimentary rock. Perhaps the most famous part of this dome is the Enchanted Rock near Llano, Texas.

The westernmost part of the state arguably has the most complex geologic history. It features a series of rock layers as well as a number of volcanic deposits and fault lines.

Moreover, the Southern Basin and Range is located in the western part of Texas. The Southern Basin and Range is a subsection of the larger Basin and Range Province, which extends throughout Nevada, Oregon, Idaho, Utah, Arizona, Texas, and northwestern Mexico.

Within Texas, the Southwest Basin and Range region is characterized by hot temperatures and desert vegetation. Much of the bedrock in these regions is igneous in origin, which was later stretched and faulted to form the mountains that we see today.

Natural History

As a result of its size, Texas contains a number of different climate zones. In the east, it has more of an oceanic (Köppen: Cfb) and humid subtropical climate (Cfa). This transitions into a hot semi-arid (BSh) and cold semi-arid climate (BSk) in the Panhandle and the southern interior part of the state before becoming a hot desert (BWh) along Texas’ border with Mexico.

Texas can be thought of as having three major climate types: Continental, Mountain, and Modified Marine. Modified Marine is found in most of the state and brings with it warm weather and a decent amount of rainfall.

Mountain climate is found predominantly in the more mountainous regions of the state, especially around the Guadalupe Mountains. Alternatively, the furthest interior sections of the state get a Continental climate, which is dominated by hot summer temperatures and relatively cold winter conditions.

This diversity of climate zones means that Texas has 11 ecological regions, with a number of different soil regions and ecosystems. In fact, while southeast Texas often gets upwards of 64” (160cm) per year of rain, the western part of the state gets just 8.7” (22cm) of rainfall.

Texas is frequently hit by thunderstorms and tornadoes, particularly in the northern parts of the state. The east is often hit by hurricanes, some of which, including Hurricane Harvey in 2017 have been particularly devastating.

Depending on where you are in the state, wildlife is abundant in Texas’ many biomes. The state has three official mammals, including the nine-banded armadillo, the Mexican free-tailed bat, and the Texas longhorn. It is also home to a number of carnivores, such as black bears, foxes, coyotes, mountain lions, ocelots, and bobcats.

In addition to mammals, Texas contains over 200 species of reptiles and amphibians. It is also home to over 590 native species of birds, making it the state with the greatest diversity in bird life in the country.

Human History

The region that is now Texas has a long and storied history that goes back thousands of years. Texas was home to a large number of native peoples before the arrival of the Europeans. These groups include the Apache, Bidai, Comanche, Coushatta, Jumano, Kickapoo, Tonkawa, Alabama, Atakapan, Caddo, Choctaw, Hasinai, Karankawa, Kiowa, and Wichita, among countless others.

Upon the arrival of Europeans, the region that would later become Texas was controlled predominantly by Spain until the Wars of Mexican Independence and, soon afterward, the Texas Revolution. At that time, the US became involved in Texan affairs, leading to the formation of the Republic of Texas, and later the annexation of the republic as a state in 1845.

Since Texas' admittance to the union, it has grown substantially in population, drawing millions to its major cities. The state’s economy is driven by its abundance of natural resources, particularly oil, mineral mining, and agriculture. These days, Texas is also becoming a large center for technology, commerce, aeronautics, and education.

Texas is also home to a large number of outdoor recreation areas, which draw visitors from around the country to experience the state’s amazing outdoor opportunities. The state has 2 national parks, as well as a number of historic sites, monuments, forests, and seashores for outdoor enthusiasts to enjoy.

Padre Island National Seashore

Padre Island National Seashore is located in Eastern Texas along the state’s Gulf Coast. It is situated on North Padre Island, a barrier island near Corpus Christi. The seashore actually contains 5 named high points, the tallest of which is Green Hill (13ft/4m).

The seashore is unique because it is located on the longest undeveloped barrier island in the entire world, with a length of 70 miles (110km). This puts it in direct contrast with the nearby South Padre Island, which is a popular resort getaway location.

Visitors to the seashore can camp on the beach and experience the region’s amazing wildlife, which include Kemp’s ridley sea turtles, which nest on the island. Padre Island is also located along the Central Flyway, one of North America’s major migratory bird routes, which makes it one of the most important bird areas on the continent.
