historic cattle trail that originated in Young county, western Texas, U.S. The trail ran southwest to connect with the Pecos River and thence up the river valley to Fort Sumner, New Mexico, and north to the railhead at Denver, Colorado. The trail was established in 1866 by cattlemen Charles Goodnight and Oliver Loving, who followed a route of the Butterfield Overland Mail, joining their herds to that of John S. Chisum in New Mexico. The route was later extended to Cheyenne, Wyoming. The arrival of the railroads to western Texas in the early 1880s made the long cattle drives unnecessary, and the trail was to all purposes abandoned. Its role in Texas history and legend is celebrated in Larry McMurtry (McMurtry, Larry)'s 1985 novel Lonesome Dove.
