On January 8, 1830, the first pack train to pass from Santa Fe, New Mexico, to Los Angeles crossed Las Vegas Valley. Antonio Armijo, a Santa Fe merchant, commanded the train and its 30 drovers. The successful completion of the journey opened a trade route between the two Mexican provinces of New Mexico and California. Described as the "longest, crookedest, most arduous pack mule route in the history of America," Armijo's party brought manufactured goods to Los Angeles and returned driving herds of mules and horses. Later termed the Old Spanish Trail, this route was a principal means of reaching the Pacific Coast until the termination of the war with Mexico in 1848
