Description

This is a digitized image of a printed paper map of the Ryerson Lake, Ontario region (Sheet No. 052L06), published in 1950. It is the first and only edition of this map, which shows both natural and man-made features such as relief, spot heights, administrative boundaries, roads, railways, trails, waterways, bridges, buildings, mills, power lines, terrain, and land formations. The image includes coverage of Manitoba, Canada. The survey for this map was conducted in 1948 by the Royal Canadian Air Force, as part of a national topographical survey originally commissioned by Department of Militia and Defence in 1904. Surveys for Ontario were completed by one of two Canadian Government Agencies: the Survey Division of the Department of Militia and Defence (after 1923: the Geographical Section, General Staff, Department of National Defence) and the Geological Survey in the Department of Mines (after 1935: the Mapping Branch of the Department of Energy, Mines and Resources). Original maps were digitally scanned and georeferenced as part of the Ontario Council of University Libraries (OCUL) Historical Topographic Map Digitization Project.
