San Marcos: IH-35 @ FM-3407

Formed around the spring-fed San Marcos River, San Marcos developed into a university city on the corridor between Austin and San Antonio. The river begins at San Marcos Springs, where water remains near 72°F year-round and supports several protected species. Texas State University, founded in 1899 as Southwest Texas State Normal School, gives the city centre a collegiate rhythm and anchors a campus above the river. The Meadows Center for Water and the Environment interprets the springs and their ecological importance, while paddling, swimming and tubing are part of local river culture.

The terrain of Texas ranges from pine forests in the east to deserts and mountain ranges in the west, creating striking contrasts in climate, vegetation, and settlement. The state also stretches from the Gulf of Mexico coast to the High Plains, with the limestone hills of the Hill Country lying between. The Rio Grande forms much of Texas’s border with Mexico and has long shaped its geography and cross-border connections. Austin, the state capital, is a major centre for music and technology, while San Antonio’s Alamo recalls the 1836 battle central to Texas history. Ranching traditions, Mexican and Indigenous heritage, and a vast road network give the state a distinctly varied character.

The Atlantic, Pacific and Gulf coasts define much of the United States — their ports, fisheries and trade routes have long tied the country’s economy to the wider world. Between them, the Rocky Mountains, Great Plains and Mississippi River basin form sharply different regions, from high western ranges to broad agricultural heartlands. Cities carry much of the national story: New York’s Statue of Liberty, a gift from France dedicated in 1886, remains an enduring symbol, while Washington, DC concentrates major federal institutions. Indigenous nations have shaped these lands for millennia, and their living cultures remain essential to the country’s identity.
