Figure 8:  Historic map reconstruction of furnaces and associated structures of the post-1860’s  Musconetcong Iron Works shown relative to the 1901 Singer Company and modern Compac Corporation buildings.  With the exception of the cut stone retaining wall, Furnace Falls Dam and the Furnace “Reservoir”, no data for the earlier 1840 - 1855 Sussex Iron Company  are mapped.  Composite is derived from the scaled computer overlay of six historic maps of Compac Corporation property, the 1858 Map of Lands Lying in Stanhope and Vicinity by Roome & Son, Surveyors (Figs. 16-17), five Sanborn Insurance maps (1886, 1896, 1901, 1909 and 1920), and two modern property surveys (Secco 1979 and Romano 2001).  Scale is approximate.
