Chapter 15: Industry/Manufacturing
1) extraction industries, including oil drilling, rock quarrying, gravel pits, and mining.
2) processing industries which are divided into three: a) mechanical processing including saw mills, grain mills, ore concentration plants, hydroelectric plants, water purification plants, and sewage treatment plants; b) chemical processing including petroleum refining and production of chemicals; and c) heat processing including thermal electric plants, cement production plants, and iron production plants.
3) fabrication industries which involve the “use of the output of processing industries to form or assemble finished products.”[iii] Examples are production of structural steel, shipbuilding, and locomotive and car production. These are the most difficult to identify on air photographs because activities are hidden from view in well-constructed buildings and enclosures.
Not all of these industries are found in Manitoba, but a few examples are shown here, and others have been shown in previous photos, for example, oil drilling (figures 13.11 and 13.12), gravel pits (figures 13.1 to 13.8), and mining (figures 13.9 and 13.10). Some activities associated with water—hydroelectric plants and sewage treatment plants—are included in the section on water resources.

15.1: Oil Wells Near Virden
Oil production in
Despite the large number of wells they have little impact on the natural environment. The oil pumps take up only a few square metres of land with slightly more being used where oil and saltwater storage tanks are located nearby.[iii] The surrounding land can be used for agriculture. Pumps are small enough that they are scarcely visible on air photos. However, a few are indicated 1; pipelines running between wellheads 2 often best pick them out.
The photo shows the town of
The CP railway line 8 runs southeast/northwest through Virden before splitting in the north 9. Roads in the town are parallel to, and at right angles, to the railway. The Trans-Canada Highway 10 is twinned 11 as it bypasses Virden to the north. PR 259 12, which crosses the Assiniboine River north of town, eventually joins the Trans-Canada Highway off the photo to the west.
Other features to note are the Virden airfield with grassed runways 13 and a terminal building 14; a drive-in cinema northeast of town 15; and a racetrack 16 with an associated arena 17 and curling rink 18 northwest of it.
