On June 6th, 1765 Charles Mason and Jeremiah Dixon placed an oak post at the point on their survey where the West or Mason-Dixon Line (northern boundary of Maryland) inter- sected with the North Line that formed the boundary between Maryland and the lower three counties of Pennsylvania (later to become Delaware). The survey divided the lands of the Calverts (Maryland), and the lands controlled by William Penn(Pennsylvania). The current permanent marker was set at this location in 1849.

Now, 250 years later, and because of the dedication of volunteers and the financial sup- port of the community, a new public trail provides access to this unique place in our na- tion’s history. This 4-mile looping trail meanders through mature hardwood forests, roll- ing meadows, and around wetlands within White Clay Creek Preserve, in Pennsylvania and White Clay Creek State Park, in Delaware, to the Tri-State marker.

Please join the Friends of White Clay Creek Preserve and the Wilmington Trail Club as we celebrate the accomplishments of the Mason/Dixon survey and dedicate the completed northern segment of the trail to the Tri-State Marker on National Trails Day. Highlights of the celebration include: • The Tri-State Trail Discovery Hike: This self-guided 1.7 mile (one-way) hike along the new trail will feature stations to explore along the way including activities for children, information about the Mason Dixon Survey, Native and Non-Native Plant Identification, and more. Access is from the Parking Lot on Arc Corner Road (off Chambers Rock Road) in Pennsylvania. • Wilmington Trail Club will lead 4 hikes. The 9-mile and 4-mile (round trip) hikes will leave from the pavilion at the Carpenter Recreation Area, in Delaware. A 10-mile hike will leave from the Appleton Road Parking area of the Fair Hill Natural Resources Area in Maryland. A 15-mile hike will leave from the London Tract Meeting House in Pennsylvania. • A Dedication Ceremony of the completed northern segment of the trail to the Tri-State Marker and a celebration of the 250th Anniversary of the setting of this point.
