A map of the Great Lakes Basin showing the five sub-basins. Left to right they are: Superior (magenta); Michigan (cyan); Huron (green); Erie (yellow); Ontario (red). Though the five lakes lie in separate basins, they form a single, naturally interconnected body of fresh water, within the Great Lakes Basin. As a chain of lakes and rivers, they ...
Diorama of an underground salt mine in Germany. Inside Salina Veche, in Slănic, Prahova, Romania.The railing (lower middle) gives the viewer an idea of scale. Before the advent of the modern internal combustion engine and earth-moving equipment, mining salt was one of the most expensive and dangerous of operations because of rapid dehydration caused by constant contact with the salt (both in ...
The Whiskey Island mine is a salt mine in downtown Cleveland, Ohio owned by Cargill Deicing Technology. It is one of the largest salt mines in the world [1] and one of two in the Cleveland area, the other being Morton Salt's Fairport Harbor mine to the east. [2] It is also one of three mines in the United States owned by Cargill. [3]
Paleo-Indian cultures were the earliest in North America, with a presence in the Great Plains and Great Lakes areas from about 12,000 BCE to around 8,000 BCE. [citation needed] Prior to European settlement, Iroquoian people lived around Lakes Erie and Ontario, [2] Algonquian peoples around most of the rest, and a variety of other indigenous nation-peoples including the Menominee, Ojibwa ...
Stansbury's 1852 map of the Great Salt Lake and adjacent country in the Utah Territory. There are several maps dating back to 1575 that show the Great Salt Lake at the correct latitude and longitude, within an accuracy of a few degrees. [citation needed] One example is a map by Nicolas Sanson dated 1650. [8]
The mine is 530 metres (1,750 feet) below surface, [38] extending 7 km 2 (2.7 sq mi) under Lake Huron - roughly the size of the town. It is the largest underground salt mine in the world. [37] The salt deposits at Goderich are from an ancient sea bed of Silurian age, part of the Salina Formation.
The Great Lakes Basin consists of the Great Lakes and the surrounding lands of the states of Illinois, Indiana, Michigan, Minnesota, New York, Ohio, Pennsylvania, and Wisconsin in the United States, and the province of Ontario in Canada, whose direct surface runoff and watersheds form a large drainage basin that feeds into the lakes.
Visitors at the Bonneville Salt Flats. The thickness of salt crust is a critical factor in racing use of the salt flats. The Bureau of Land Management (BLM) has undertaken multiple studies on the topic; while a 2007 study determined that there was little change in the crust's thickness from 1988 to 2003, [8] more recent studies have shown a reduction in thickness, especially in the northwest ...
