2014 Map of Mounds

About this map

The town of Marmaduke and its rural surrounds in Greene County are defined by a complex network of drainage ditches and ancient ridge formations that rise above the flat alluvial plain. Early 21st-century infrastructure follows the grain of the land, with Us-49 cutting diagonally across the landscape toward Dixie, passing through the small community of Jay. The hydrography here is dominated by the wandering Cottonwood Slough and White Walnut Creek, while topographic elevations like Horse Island Ridge and Brushy Ridge provide a glimpse into the underlying geological history of the St. Francis Basin.
