Alexey W. Von Schmidt

The Von Schmidt State Boundary Monument was designated a California Historic Landmark (No. 859) on April 26, 1973. In 1873 San Francisco civil engineer Allexey W. Von Schmidt built the State Boundary Monument in San Bernardino County, California, near Needles, California. In 1872 and 1873 Von Schmidt did a survey of the border between California and Nevada/Arizona. The California Historic marker is on the dirt road, Pew Road, also called River Road, 2.6 miles (4.2 km) south of the State Line; 14 miles (23 km) north of Needles. The marker is not at the current state boundary, as Von Schmidt made an error in his survey. A new survey in 1893 showed that the Von Schmidt line was 1,600 to 1,800 feet (490 to 550 m) off to the west. The marker is at the southern end of the California-Arizona State boundary. In 1872, a dispute arose between Nevada and California about the location of the state's boundary. Nevada wanted the state divide to be the same as the Sierra Nevada mountain range divide. California wanted the line to the east of the mountain range. When California attained statehood in 1850, it adopted 120 degrees west longitude as its eastern border. Between 1855 and 1900 there were six surveys to locate 120 degrees, with each locating 120 degrees of longitude differently. Von Schmidt applied for and was granted the contract to survey the state's frontier border east of the Sie
