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.

Also of interest on the photo are some gravel pits not seen on previous photos. These pits that are usually light-toned 4 are depressed areas and should not be confused with other light-toned elevated areas 5. The latter result from rain splash erosion of soils; usually they have less well-defined boundaries than gravel pits.
Aside from these features it is worth noting the irregular section line between sections 6 and 7, township 10, range 18 6. Another somewhat unusual feature in this part of
