1872 California-Nevada State Boundary Marker

The cast iron obelisk stands at the precise intersection of California and Nevada state lines, marking the territorial division established through official surveys.

The boundary marker, constructed in 1872 under architect Alexey Von Schmidt's direction, represents the culmination of multiple state border surveys between 1855 and 1900.

The marker's National Register of Historic Places designation underscores its role in defining territorial boundaries during the development of the American West.

Located at coordinates 39.524389, -120.001861, the marker is enclosed within a protective fence and integrated into a landscaped park setting.

Despite technological advancements, the marker sits approximately 525 feet west of the actual 120-degree longitude line it was intended to mark.
