A finely detailed late-nineteenth-century state map of New Jersey published by the prominent American cartographic firm G.W. & C.B. Colton & Co. The map depicts New Jersey divided into its various counties, distinctly delineated with contrasting hand-colored washes in pastel shades of pink, green, and yellow. Comprehensive regional detail extends into surrounding portions of eastern Pennsylvania, southern New York, and Long Island Sound, grounding the state in its mid-Atlantic geographic context. The cartography highlights the rapid post-Civil War infrastructure development across the state, illustrating dense networks of operational and proposed railroad lines, canals, turnpikes, and post roads. Topographical features including coastal barrier islands, marshlands, bays, and mountain ridges are rendered with delicate hachuring alongside fine typography identifying hundreds of towns, villages, depots, and township boundaries.
