This cache is dedicaded to Albert Pellew Salter (1816 - 1874) who was a provincial land surveyor in Ontario in the mid-19th century. 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 (Sturgeon Falls) Lake Nipissing in 1856. In 1847, he was hired by the Commissioner of Crown Lands to survey mining locations in the Sault Ste. Marie region. In 1855, he was assigned to survey the North Shore of Lake Huron, in light of the recent Robinson-Huron Treaty. The following year, he returned to the region to survey the first baseline, and detected the magnetic anomalies as he passed between Round Lake and Whitefish Lake on what is now the Whitefish Lake First Nations reserve. Salter's Meridian is commemorated by a historical plaque in the Naughton neighbourhood of Sudbury and street name "Salter" in various Northern Ontario municipalties.
