1872 California-Nevada State Boundary Marker, Political boundary marker in Washoe County and Sierra County, United States.
The 1872 Boundary Marker is a cast iron obelisk standing at the state line between California and Nevada, marking the official division between the two territories. This monument sits within a landscaped park area and is protected by a surrounding fence.
The obelisk was built in 1872 under architect Alexey Von Schmidt's direction, concluding decades of surveys that began in 1855. Its construction finalized the official border delineation work between California and Nevada.
The marker makes the boundary between two states tangible and visible to those who visit. It serves as a physical reminder of how territorial divisions were presented to settlers and travelers crossing this mountain landscape.
The marker sits in a protected fenced area that allows for safe viewing and examination. The best time to visit is during drier months, as the mountain region can be challenging in winter.
The obelisk stands roughly 525 feet west of the actual 120-degree longitude line it was intended to mark. This offset reveals how challenging early surveying techniques were in difficult mountain terrain.
