Three miles east of Lusk on U.S. Highway 20 stands a marker denoting the location of a branch of the historic Texas Trail. In 1894, some 800,000 head of wild, longhorn cattle from Texas were moved along the trail into the territories of Wyoming and Montana to stock the open ranges. Thus the cattle industry in those states was born.
The Texas Trail, in use from 1876 to 1897, entered Wyoming at the city of Pine Bluffs. The route ran almost parallel to the Cheyenne-Deadwood Stage Road before following the Little Powder River into Montana. Today, visitors can learn more about the history of the trail at the Texas Trail Museum in Pine Bluffs.
