Llano Estacado

An Island in the Sky

El Llano Estacado, a major new work of Western History, reveals the historical heart of one of the world’s unique regions--the enormous mesaland of the Southern High Plains in Texas and New Mexico. From the Canadian River in the north to the Edwards Plateau in the south, from the Pecos River in the west to the fantastic canyonlands of the Red, Pease, Brazos, and Colorado Rivers in the east, the 50,000 square miles of "the Llano" are chronicled over three centuries with an eye to the history and compelling mystery of this special land.

Commemorating 250 years of American independence through the stories, people, and places that shaped Texas and the nation.

As the United States approaches its 250th anniversary in 2026, Texans have a unique opportunity to reflect on the state’s role in the American story. Through exhibitions, programs, educational initiatives, and community events across Texas, Texas America250 encourages celebration, reflection, and commemoration at both local and statewide levels. At the Texas State Historical Association, we are proud to support this important moment through our mission-driven work in history education and public engagement, including Texas History Day, and we invite students, educators, and communities to explore this milestone in meaningful ways.

On July 4, 2026, we will celebrate the 250th anniversary of the adoption of the Declaration of Independence and the birth of the greatest nation in the history of the world. “We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.” Long may these ideals live in the heart of every Texan and every American. May God bless all who have defended our freedoms that we enjoy each day. And God bless the United States of America.

Greg Abbott, Governor of Texas
