New survey of Wisconsin effigy mounds used Lidar and GIS technology to analyze mound layouts, revealing geometric patterns across regional networks. Earlier surveys relied on basic mapping methods with limited precision. Researchers suggest the geometric relationships may hold cultural meaning, though interpretation remains ongoing.
