Llano Estacado—Coronado’s term for it, meaning “palisaded plains” of West Texas, a country populated exclusively by the most hostile Indians on the continent, where few U.S. soldiers had ever gone before. The llano was a place of extreme desolation, a vast, trackless, and featureless ocean of grass where white men became lost and disoriented and died of thirst; a place where the imperial Spanish had once marched confidently forth to hunt Comanches, only to find that they themselves were the hunted, the ones to be slaughtered.
