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.

This area situated near the apex of the Assiniboine Delta is an excellent source of gravel. Spurs from the CN line 7 run into two long (light-toned) gravel pits 8. Pits are also located in other areas; some—light-toned—appear to be active 9 whereas others are overgrown and therefore have a patchy dark tone 10, and others are filled with water 11.
In the extreme east is a chemical plant 12 close to the
In addition to the industry there is some evidence of agriculture. Dugouts 19 suggest livestock grazing in this area with permeable soils developed on sand and gravel.
