History
Boulder Wash was part of the original 1829 Armijo Route of the Old Spanish Trail along the Colorado River, between the mouth of the Virgin River and mouth of Las Vegas Wash. That trail route bypassed the deep narrow gorge of Boulder Canyon through the Black Mountains by way of Boulder Wash, Pinto Valley and Cottonwood Spring to upper Callville Wash which it then followed down to the river. Boulder Wash was a tributary of the Colorado River until the construction of Hoover Dam and the formation of Lake Mead.
