Alexey W. Von Schmidt, Boundary marker in San Bernardino County, US.
The iron column marker stands as a testament to early land surveying efforts between California and Nevada, marking a historical border point.
Civil engineer Alexey W. Von Schmidt erected this marker in 1873 to establish the boundary between California and Nevada following his comprehensive survey.
The marker represents a vital chapter in American westward expansion, demonstrating the technical methods used to define state territories in the 19th century.
Located on Pew Road, approximately 2.6 miles south of the State Line and 14 miles north of Needles, the marker serves as California Historical Landmark 188.
The boundary line marked by Von Schmidt contained a calculation error, placing it 1,600 to 1,800 feet west of the actual border location.
