This is a 30 foot secondary mound on which once stood a temple containing sacred Indian images. At least two small mounds stood along the north and south sides of the primary platform. These mounds may have supported structures of wood plastered with clay.
Frank Lloyd Wright designed this house between 1948-1950, and was built 1950-1954. It is designed in the Usonian style. It is currently under renovation, and not open for tours. This is the closest look I could get.
