Stretching for 130 miles across Clark County, this historic horse trail became Nevada’s first route of commerce in 1829 when trade was initiated between Santa Fe and Los Angeles. The trail was later used by the wagons of the “49ers” and by Mormon pioneers. Concrete posts marking the trail were erected in 1965.

Early Spanish traders named the fifty-five dry miles separating Las Vegas and the Muddy River the Journada Del Muerto (Journey of The Dead Man). This longest stretch without water along the Old Spanish Trail was littered with the skeletons of animals and parts of wagons abandoned along the sandy desert. Most experienced travelers made the trip at night.
John C. Frémont crossed the Journada in 1844 and commented: “We ate the barrel cactus and moistened our mouths with the acid of the sour dock. Hourly expecting to find water, we continued to press on to midnight, when after a hard and uninterrupted march of 16 hours, our wild mules began running ahead; and in a mile or two we came to a bold running stream (the Muddy River).

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 merchant in Santa Fe, commanded the train and roughly sixty men. The successful completion of the journey opened a trade route between the two Mexican provinces of New Mexico and California.
Following the “longest, crookedest, most arduous pack mule route in the history of America,” Armijo’s party and others brought woolen goods to Los Angeles and returned to Santa Fe driving herds of valuable mules and horses. Later termed the Old Spanish Trail, this route was the principal means of transportation between the two Mexican territories, until the end of the Mexican War in 1848.

This portion of the Old Spanish Trail [Mountain Springs Pass] was discovered in January 1830, by Antonio Armijo during his first trip from Santa Fe to Los Angeles. The springs just north of this marker provided excellent water and fed meadows of luxuriant grass for draft animals. Two days were required to travel between Las Vegas and Mountain Springs Pass. The trip was broken at Cottonwood Springs, the site of Blue Diamond, where an early start was usually made in order to climb the pass by nightfall. Early travellers often referred to the area as Paiute Springs, but the present title has been used for over a century. The altitude made Mountain Springs one of the favorite camping spots on the trail.
The Old Spanish Trail is listed on the National Register of Historic Places (2001 segments listed: Mormon Mesa, Blue Diamond, Stump Spring; 2008 boundary increase: near the junction of Interstate 15 and State Route 169).
Listed as a National Historic Trail in 2002.
Listed as a U.S Historic District.
Located in Clark County.
