1955 Map of Portland

About this map

The Delaware River cuts through the massive ridge of Kittatinny Mountain here, creating the dramatic geological feature known as The Gap. This mid-century landscape is defined by its complex transportation network, where the Pennsylvania and Delaware Lackawanna and Western railroads converge near the river towns of Portland and Columbia. Beyond the industrial corridor of the river, the interior of Knowlton and Blairstown reveals a rural character, marked by small settlements like Hainesburg and Vail, along with numerous youth retreats such as Camp Weygadt and Camp Mohican.
