2021 Map of Meramec State Park

About this map

The Meramec River winds through a landscape defined by dramatic karst features and spring-fed tributaries along the borders of Franklin, Crawford, and Washington counties. In this Ozark river corridor, significant water sources like La Jolla Spring, Pratt Spring, and Hamilton Spring emerge from the limestone terrain. The map details the transition from the edge of Sullivan into the dense topographic network of Meramec State Park, where hiking paths like the Wilderness Trl and Natural Wonders Trl follow the high ridges. These upland areas are deeply dissected by numerous named drainages including Sheep Ranch Hollow and Primrose Hollow. Near the center, the small settlement of Caseyville sits at a crossroads, while to the south, Pea Ridge overlooks the surrounding valleys near the Pea Ridge Cem. The crossing at Sappington Bridge serves as a key landmark for navigating the river's path through the county lines.
