Chisholm Trail
Brownsville, TX
Spanish cattle brought to Texas in the 1600s and 1700s became the hardy longhorn, and by 1860 ranching dominated the Rio Grande Valley, worked by the vaqueros whose traditions defined the American cowboy. After the Civil War, cattle worth a few dollars in Texas fetched ten times as much at midwestern railheads, so ranchers pooled their herds and drove them north from the Rio Grande through Fort Worth and into Oklahoma, where the route met the trail blazed by trader Jesse Chisholm in 1865. An estimated 10 million cattle followed the Chisholm Trail north before quarantines curtailed the drives in the late 1870s.
