Emerald and the neighboring settlement of Cylon anchor this mid-1970s survey of St. Croix County's agricultural heartland. The landscape is defined by the headwaters and tributaries of several prominent regional waterways, including the South Fork Willow River and the Rush River, which carve subtle valleys across the dairy country. A significant relic of the area's transportation history is the Old Railroad Grade passing through the northern sections, tracing a path that once connected rural economies before the rise of modern highway networks.
