In the first comprehensive history of the region, Jefferson Morgenthaler traces the history of La Junta de los Rios from the formation of the Mexico-Texas border in the mid-19th century to the 1997 ambush shooting of teenage goatherd Esquiel Hernandez by U.S. Marines performing drug interdiction in El Polvo, Texas. "Though it is scores of miles from a major highway, I found natives, soldiers, rebels, bandidos, heroes, scoundrels, drug lords, scalp hunters, medal winners, and mystics," writes Morgenthaler. "I found love, tragedy, struggle, and stories that have never been told." In telling the turbulent history of this remote valley oasis, he examines the consequences of a national border running through a community older than the invisible line that divides it.
