About this map

Indiantown Gap Military Reservation dominates the landscape of this 1947 survey, showing the extensive training grounds established in the Blue Mountain region. The map reveals a transition from the structured military presence to the rural farming communities of southern Dauphin County. In the lower portions of the sheet, the village of Grantville sits near local landmarks like the Grantville School and St Johns Church.

A series of prominent ridges including Peters Mountain, Sharp Mountain, and Second Mountain create a corrugated terrain that influenced local industry and transportation. The Dismantled Railroad following the path of Stony Creek reflects the shift away from earlier extractive or transit economies. Water resources are a central theme, with the Harrisburg Water Supply reservoir stretching through the northern valley, while Manada Creek cuts through the ridges at the distinctive Manada Gap.
