Railpictures.ca - MuskokaMoFo Photo: CP SD70ACU 7058, rebuilt from UP SD9043MAC 3551 (built 1/1997 as UP 8080), takes up the rear of CP 112 around the bend at the very top of the Parry Sound sub in Romford. While their sister “Super Stacks” in Sudbury are slowly being dismantled, one of the 2 “Twin stacks” built by Inco in 1954 and 1958 stands tall in the background. Idled in April of 1972 due to stricter environmental laws, the Coniston plant was kept as a “standby smelter” (although it was never used again), until most of the site but the towers and some original buildings was demolished in 1976. They have stood as part of the “Coniston Industrial Park” and the town’s identity ever since, briefly being studied for the feasibility of retrofitting the two dormant 120-metre tall smokestacks with wind powered generation systems in 2007, ultimately resulting in a windmill farm being built further South closer to the French River. | Railpictures.ca – Canadian Railway Photography

Out in Montana, the Anaconda smelter, when it closed down, kept their giant stack as a historical landmark. Now, the location has become a top class park.
