[This is a repost of an earlier image ... but without the foliage that was obscuring the stonework] This is one of the two Splitrock furnaces. Between 1770 and 1862, Splitrock in what is now Rockaway, NJ was host to iron mining and refining operations. Local records show that in 1822, John Dixon was assessed for taxes on two forge fires, known as Dixon's Forge, at Split Rock. The ore was loaded at the top of the furnace; the opening at the base (about 10 ft. by 10 ft.) was loaded with fuel. The stream in the foreground provided water power for the operation. The image was recorded by a Nikon Coolpix 4300, tripod mounted, automatic exposure, 2272x1704 pixels, high image quality and cropped in Photoshop 7. Thank you very much for viewing. I appreciate each and every comment that is made -- progress depends on criticism and advice as well as praise.
