I will start this post off simply by saying that the Marmora Mines site is on private property and monitored heavily by security cameras. People caught trespassing will have to deal with the police.
That being said, when we were leaving we witnessed a group of about 8 teenagers repelling down the side of the mine to get to the water. Also, the parking lot was full of cars, but we passed nobody in the sanctioned lookout area.
Following an aeromagnetic survey of the area in 1948, a steel mill company out of New York began stripping 120 metres of limestone to get to the underlying iron ore. Shipments of iron ore pellets began in 1955, and in total 1.3 million tons left the mine, and another 3.5 million tons of waste rock littered the landscape. (Source: vishwawalking.ca). The mine operated until 1979 and began to slowly fill with water from underground streams making it a present day lake. The pit stretches more than 656 feet deep and covers 85 acres at the surface (Source: ontariohighlands.ca).
Photographer friend Pat Trudeau and I arrived before 9am when there was no wind, no people, and the right amount of dramatic clouds in the sky. I had rented a wide angle lens solely for this site and it did not disappoint. The conditions were perfect. After navigating a hole in the fence, we could walk all around the pit, abandoned buildings and machinery, and even down one of the ramps to the waters edge. This landscape was epic. I often took a couple moments just to stare out and take it all in. I had a difficult time selecting a couple of my favourite shots from the site, so I’ll add my top 10.
