Historical marker beside the tower: "Bert Vaughan of Jacumba built the stone tower in 1922-23 to commermorate the pioneers and road and railroad builders who opened the area. In the 1930's W.T. Ratcliffe carved the stone animal figures which lurk in the rocks surrounding the tower, creating a fantasy world of surprise and strange beauty. This remarkable sculptural assemblage is one of California's exceptional folk art environments."
