What Are Some Ley Lines Maps of North America?

Ley lines are supposedly geographic areas of alignment where illustrated lines and circles connect around places of interest, such as megaliths and monuments. These areas are believed to have spiritual significance and power according to many New Age and traditional magical beliefs. They were first suggested to exist in 1921 in "The Old Straight Track" by Alfred Watkins. Enthusiasts believe that the ley lines resonate psychic or magical energy, especially along their points of intersection.
