Sunday Rock, a glacial erratic, was used by Indians and early settlers as a landmark when traveling into the mountains. In the early days of settlement it marked the boundary of organized law enforcement. There was none, and no Sunday, south of the Rock. The rock also became a dividing line, seperating the woods from the world. When people passed by the rock, they felt they had arrived at a place where life was freer and easier, leaving the cares of everyday life behind.
