THERE IS NO CACHE AT THE POSTED COORDINATES!
Though it's probably a great spot to begin your tour of Mason Dixon Historical Park!
Welcome to Mason Dixon Historical Park!
The publicly owned, 295-acre Original Mason-Dixon Historical Park was established in the 1970s to commemorate the great achievement of Charles Mason and Jeremiah Dixon, the English astronomers who surveyed the Mason and Dixon Line. Brown's Hill is a National Historic Landmark and the Mason and Dixon Line is a National Civil Engineering Landmark. This location has been so honored because it was on Brown's Hill that Mason and Dixon were obliged to end their survey, 23 miles short of their goal.
