Monticello - Was along the Allegheny River in Rayburn Township. It was built in 1859 by Robert E. Brown of Kittanning. He operated it successfully for several years(s&t). In 1863 it was sold to McKnight, Martin & Co., later McKnight, Porter & Co. The furnace provided employment for as many as 200 people, and its aggregated product was 60,000 tons of pig iron, which found markets in Pittsburgh and Kittanning. Between 1866 and 1874 20,000 tons of Lake Superior ore were mixed with native (carbonate) ores producing a superior quality of neutral iron, well adapted to the manufacture of nails, hoop iron and tool steel. The Allegheny Valley Railroad was extended to this point in 1865 or 1866 probably to service the furnace with ore. The furnace operations were discontinued in 1875(hac). There is very little left on this site except a nice retaining wall and lots of slag piles, the later extension of the railroad covering the site of the stack. (P)(V)(rp-2004).
