The Sudbury Reservoir (2.02 square miles) is an emergency backup Boston metropolitan water reservoir in Massachusetts, located predominantly in Southborough and Marlborough, with small sections in Westborough and Framingham. It is the second-largest verified impact crater on Earth, as well as one of the oldest.[2][3].

Sudbury's early growth was constrained by railway lines and the area's topography, as well as by the lack of a sound tax base (the community did not begin receiving any taxes from the mining industry until the advent of regional government in 1973). Water began to fill the reservoir on February 8, 1897, with construction of the reservoir's new Sudbury Dam on the Stony Brook Branch of the Sudbury River completed later that year.[4].

Thanks for contributing to The Canadian Encyclopedia. We tackle difficult conversations and divisive issueswe dont shy away from hard problems. Joyce, D. and Poulin, R. (2020): Sudbury Mining District History, Geology and Mineralogy. A meteorite of sufficient size to create a crater as large as the Sudbury Basin should only be partially vaporised on entry, which leaves a 'comet-as-culprit' scenario as by far the most likely. I would argue that you cant be part of the solution until you see yourself as part of the problem. Much of Sudburys original crater, thought to have measured at least 200 kilometers (120 miles) across, has been deformed and eroded. When the Superstack was constructed in 1972, it was the tallest structure in Canada and the tallest smokestack in the world. F. W. Beales, G. P.

The judicial seat for the District of Sudbury, the City of Greater Sudbury is located on the western shore of Ramsey Lake, about 60 km north of Georgian Bay. Young people in Sudbury, Ontario, jump off rocks into Silver Lake, once one of the most polluted bodies of water in the world.

As of 2016, the citys population was 164,689. The northern Ontario city has worked hard to shed that moonscape imagewith extensive regreening efforts over multiple decades, but the Apollo connection remains. Increasing international tensions and competition for minerals may also make the area more attractive as governments become increasingly concerned with developing domestic supply chains. The superstack now stands dormant and slated for demolition. As David Pearson, a driving force behind Sudburys transformation says, Thats what we need to take from the Sudbury story, and we need to apply it to today.. In contrast to the more temperate, fertile areas of what is now southern Ontario, the area around Ramsey Lake was relatively sparsely populated.

Collaborative research led by geologists at Trinity College Dublin has found strong evidence that one of the largest preserved impact structures on Earth was caused by a comet colliding with our planet over 1.8 billion years ago. has become a major centre for development of mining technology. When completed, the reservoir's surface area was 2.02 square miles (5.2km2), its average depth was 17 feet (5.2m) and maximum depth was 65 feet (20m), and its capacity was 7.253billion US gallons (27.46billion litres).

Subsequent geological processes have deformed the crater into the current smaller oval shape. This series explores efforts around the world to seek justice and restitution for communities subjected to historical harms. By March 1883, they had erected the towns first buildings. The Sudbury model: How one of the world's major polluters went green [2] The mining company Vale finished the final steps to take it out of service in July, replacing the towering structure with two smaller stacks that require far less energy to operate and will reduce greenhouse gas emissions at the smelter by approximately 40%. This is due to the abundance of ore deposits rich in nickel and copper, which were discovered here long before people were aware of the basins cosmic origin. Explore them here. the largest community in northern Ontario. These deposits were found long before the impact crater itself. Gisele Lavigne lives in the Copper Cliff neighborhood at the Superstacks base. ore on open wood fires to extract the desired minerals from it, vegetation in Sudbury became sparse, consisting mainly of poplar and birch species. "I've been pleased to see Sudbury become much more, shall we say, cosmopolitan and diverse with several big science projects involved," he said, referring to the underground Sudbury Neutrino Observatory (SNOLab), and its science, geological and mining projects. "We had a much more conventional geological type tour," Dence said. The object responsible for creating Sudbury Basin crashed into Earth about 1.8 billion years ago. But today Sudbury enjoys some of the cleanest air quality in Ontario. Due to the high mineral content of its soil, the floor of the basin is among the best agricultural land in Northern Ontario. For the Apollo 16 training session, Dence said, NASA decided to make Sudbury a mock traverse on the moon for the July 7-9 training. Early methods of roasting the ore polluted the landscape locally, while later smelting techniques expanded the damage regionally. Formation The Sudbury basin was formed by a strike from a bolide about 10-15 km (6.2-9.3 mi) in diameter. The lowest beds of the Group, the lower Onaping Formation, represent impact-generated breccia and fall-back material, the upper Onaping Formation and the overlying Onwatin Slates represent the restricted crater series, while the succeeding Chelmsford Sandstone represents an open marine turbidite sequence. The Sudbury Fight (April 21, 1676) was a battle of King Philip's War, fought in what is today Sudbury and Wayland, Massachusetts, when approximately five hundred Wampanoag, Nipmuc, and Narragansett Native Americans raided the frontier settlement of Sudbury in Massachusetts Bay Colony.Disparate companies of English militiamen from nearby settlements marched to the town's defense, two of which . 50 years ago, astronauts trained in Sudbury, Ont., for the Apollo 16 moon mission.

The Sudbury Impact Basin is the deeply eroded remains of the 1.85 Ga original bolide impact that formed a 200-250 km multi ring crater with a core comprising of an elliptical, 60 x 30 km layered 2.5 km thick impact melt sheet referred to as the Sudbury Igneous Complex (SIC). So we were all part of the problem here. The enormous heat of the impact melted and mixed these rocks together, effectively combining the main ingredients for magmatic deposits. Nobody was going to say anything against the company, essentially, says Peter Beckett, an ecologist at the university and chair of the citys advisory panel on regreening.
