Maryland Pennsylvania West Virginia Tripoint, Maryland

This is a point where you could be in three states at once. It is one of 35 points in the USA where three state lines meet on land (another 27 are in water). There is a stone monument here, originally placed there in 1910, and another placed in 1967 by the Boy Scouts, commemorating the bicentennial of the completion of the survey of the Mason and Dixon line here in 1767.
