Beale's Crossing was a river crossing on the Colorado River, near the head of the Mohave Valley, between New Mexico Territory (now Arizona) and California along the 35th Parallel route of Beale's Wagon Road. It was at what became the site of Fort Mohave in what is now Fort Mohave, Arizona, west of Beaver Lake, Nevada. It was named for Edward Fitzgerald Beale, who lead the expedition that built what came to be called Beale's Wagon Road from Albuquerque, New Mexico to Beale's Crossing in California, then by way of the Mohave Trail/Old Spanish Trail, and another old route west from the Mojave River to Fort Tejon, California.
