About Willamette Stone State Heritage Site

This small forested park in the hills west of Portland protects the Willamette Stone, the initial point from which the Willamette Meridian and baseline were laid out. Those survey lines were later used to divide land across Oregon and Washington. Visitors walk a short trail downhill from the parking area to reach the current monument, where they can view and read about the marker. The state acquired the property in 1945 to preserve the site. The original marker was an 1885 stone obelisk that replaced an 1851 cedar stake placed by the territorial Surveyor General. Because the park sits in a county with restrictions on certain tree materials, visitors are asked to avoid bringing in firewood from outside the area.
