Serpent Mound

The 1,348-foot Great Serpent Mound — the world's largest serpentine effigy earthwork — coils along a ridge above Brush Creek with its head aimed toward the summer solstice sunset. Built over a 320-million-year-old meteorite impact crater, the site generates measurable geomagnetic anomalies. Dowsers, sensitives, and scientific instruments all record something unusual in the energy field here. Native oral traditions describe it as a place of immense power where the boundary between worlds is thin, and visitors frequently report time distortion — feeling that hours have passed when only minutes have elapsed.
