1920 Map of Petersburg

About this map

South Br Potomac R and the Baltimore and Ohio railroad corridor anchor this early 20th-century survey of the Appalachian highlands. The landscape is defined by the steep parallel ridges of North Fork Mountain and South Fork Mountain, where isolated communities like the Smoke Hole Settlement established a foothold. Cultural life in the gaps and valleys is evidenced by an exceptionally high density of rural schoolhouses, including the Royal Glen School near the Royal Glen Mill and the Sweedlin Valley School to the south.
