Arthur Saint Cyr (1860 – 1923)
	
Arthur Saint Cyr was a Dominion Land Surveyor.((//Sessional Papers, Volume 9.// Second Session of the Seventh Parliament of the Dominion of Canada. Ottawa: 1892: 29-30.)) Between 1886 and 1893, Saint Cyr worked with surveyors William Stuart Drewry and James J. McArthur on the Canadian Pacific Railway Survey, mapping a significant area along the route between Canmore, Alberta and Revelstoke, British Columbia.((“James J. McAcArthur.” //Wikipedia,// 2024 website: James J. McArthur - Wikipedia))
 
In 1887, Saint Cyr was engaged in defining the boundary of the Rocky Mountain Park at Banff. In 1888 he completed the Rocky Mountain Park boundary and some minor surveys in the Bow Pass and spent the last part of the season surveying the Columbia River to define the southern limit of the railway belt.((//Sessional Papers, Volume 9.// Second Session of the Seventh Parliament of the Dominion of Canada. Ottawa: 1892: 29-30.))
	
In 1892, Canada and the United States agreed to a joint survey of the contested part of the Alaskan Panhandle. The completed data would allow the boundary to be placed within the spirit and intent of the existing treaties. The United States would survey along the major rivers and the Canadians would survey the intervening areas. Four American and seven Canadian parties were sent out in 1893. Dominion Land Surveyor Arthur Saint Cyr was in a Canadian party in the Unuk River area in the far south. The weather was poor in 1894 and not much was accomplished. In 1894, Saint Cyr was surveying in the Portland Canal-Chickamin River area in the south. The maps drawn by both countries were completed that season.((Lewis Green, //The Boundary Hunters.// Vancouver: University of British Columbia press, 1982: 54-57, 62-63.))
	
In the spring of 1897, Saint Cyr was chosen to find and survey an all-Canadian wagon road or railway route from Telegraph Creek in British Columbia to the head (south end) of Teslin Lake for the expected hordes of gold seekers. His assistant was W. Morley Ogilvie, DLS, son of William Ogilvie, DLS. After finishing the survey, Saint Cyr travelled from Teslin to Marsh Lake in November 1897 along the McClintock Lakes to see if a trail was feasible.((R. C. Coutts, //Yukon: Places & Names.// Sidney, B. C.: Gray’s Publishing Ltd., 1980.)) Saint Cyr explored the east side of Teslin Lake in 1897. He continued down the Teslin River to its junction with the Yukon.((Arthur Saint Cyr, //Exploration of the Country East of Teslin Lake: Report of Arthur Saint Cyr, D.L.S.// Nabu Press, 2011 reproduction.)) William Mackenzie and Donald Mann, experienced in the rapid building of railways, signed contracts with Ottawa in January 1898 to build a narrow-gauge railway from the Stikine River, near Telegraph Creek, to the southern end of Teslin Lake.((Gordon Bennett, //Yukon Transportation: A History.// Parks Canada Occasional Papers #19, Ottawa, 1978.)) Minister of the Interior Cifford Sifton supported the bill to charter the railway on the Stikine River route but it was defeated by the Senate in March 1898.((Rod Macleod, //Sam Steele: A Biography.// University of Alberta Press, 2018: 166.)) The project was abandoned after only twelve miles of track was laid.((Gordon Bennett, //Yukon Transportation: A History.// Parks Canada Occasional Papers #19, Ottawa, 1978.))

Saint Cry explored the Nisutlin and Big Salmon rivers in 1898.((Arthur Saint Cyr, //Exploratory survey of the Nisutlin & Big Salmon Rivers in the Yukon Territory.// Ottawa: Topographical Surveys Branch, 1898.)) Saint Cyr’s party occupied ten triangulation points on various mountain peaks and called the last one "Last Peak."((R. C. Coutts, //Yukon: Places & Names.// Sidney, B. C.: Gray’s Publishing Ltd., 1980.))
