2021 Map of Antelope Island

About this map

Lake Sharpe dominates the center of this landscape, marking the widened Missouri River as it flows through the Great Plains. Along the southern banks, the Fort Pierre National Grassland encompasses a significant portion of the territory, defined by a network of seasonal drainages including Antelope Cr, Sand Cr, and Timber Cr. These waterways cut through the high ground, creating prominent local features such as Taylor Draw and Mosteller Draw.
