"S" is for Sugarloaf Mountain (Chesterfield County). Sugarloaf Mountain is an erosional remnant located in the Sand Hills State Forest within the upper coastal plain. It lies 513 feet above sea level and 100 feet above the surrounding terrain. From this position and elevation, Sugarloaf offers a wide view of the surrounding landscape. The sand dunes and clays that make up Sugarloaf were originally rocks of the various mountain ranges that formed beginning in the Ordovician period and continuing during the Devonian and Permian periods and then wore away. Sugarloaf is made up of sands, clays, and a sandstone that is capped in places by ironstone that formed as iron-rich water percolated through the sands, forming a hard, almost impermeable layer. Sugarloaf Mountain is one of the few sites where abundant ironstone is found in the Sandhills.
