1955 Map of Holtwood

USGS Topo · Published 1990

About this map

The Susquehanna River Conowingo Reservoir and Lake Aldred dominate this mid-century landscape, split by the Holtwood Dam. The map reveals a region defined by hydroelectric power and river-dependent transport, with the massive powerplant and various islands like Bear Island (Upper) and Mt Johnson Island punctuating the waterway. On the eastern shore, the Penn Central line follows the riverbank past Midway Sta, while the western side features more rugged terrain carved by Muddy Creek.
