Old Spanish National Historic Trail

In December 2002, the Old Spanish Trail was designated a National Historic Trail by Congress. The Trail is jointly managed by the Bureau of Land Management (BLM) and the National Park Service (NPS), working in partnership with other federal, state, and local government agencies, and private landowners who manage or own lands along the trail route. The Old Spanish National Historic Trail extends 2,700 miles across New Mexico, Colorado, Utah, Arizona, Nevada, and California to link Santa Fe and Los Angeles.

Antonio Mariano Armijo (1804 - 1850), a Spanish explorer and merchant, led an expedition of 60 men and a pack string of 100 mules and established the first trade route from Abiquiu, New Mexico to California in 1829 -1830. Armijo and his men traded tanned hides, blankets and other wool products for horses and mules, which were sold in New Mexico. His route, the southernmost and most direct, is known as the Armijo Route of the Old Spanish Trail. Armijo’s route joined the Mojave River at its mouth near what is now Soda Lake and followed the River to the foot of the mountains at Summit Valley, down Cajon Pass and into Alta/Nueva (New) California. The second southern route extended from Las Vegas to Tecopa to Barstow to Victor Valley and down Cajon Pass. About 128 miles of the Old Spanish National Historic Trail crosses through the Barstow Field Office.

Two branches of the OST cross within or along the boundaries of the Beaver Dam Wash NCA. The Main Branch of the OST generally followed the corridor of modern-day U.S. Highway 91, north-south through the NCA. The Armijo Branch is currently believed to have been through Bulldog Canyon, along the southeastern boundary of the NCA.
