Albert Pellew Salter (1816–1874) was a provincial land surveyor in Upper Canada then Ontario in the mid-19th century.
[1] He is historically most notable for having discovered magnetic abnormalities at what is now Creighton Mine in Greater Sudbury, while surveying a baseline westward from Lake Nipissing in 1856.
[1] He subsequently married in 1839 and taught school while obtaining his degree in land surveying and civil engineering.
[1] The area was then examined by Alexander Murray of the Geological Survey of Canada, who confirmed "the presence of an immense mass of magnetic trap".
[1] The later construction of the Canadian Pacific Railway through the area, however, made mineral exploration more feasible and finally resulted in the development of a mining settlement in 1883.
