It lies 1.0 miles east-south-east of Ballwin, MO (from Ballwin, MO: bearing 108°T), and is situated 5.7 miles south-south-east of Chesterfield. Rolling hills, cloaked in a mosaic of dense woodland and open fields, define its character, their contours softened by the broad strokes of the Midwestern sky. In the late afternoon, the sunlight, filtered through the leaves of mature oaks and maples, paints the air with a honeyed luminescence, a quiet benediction on the land.
