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.

15.10: The Pas in 1973
This newer, slightly larger-scale photo of The Pas illustrates the usefulness of an increase in scale to detect details and of sequential photos to detect changes.
In the south railway cars on sidings 1 and a round house 2 are clearly visible. Further north a long building with railcars beside it 3 can be seen with the railway station (dark-toned) 4 north of that.
Additions since figure 15.9 was taken include a race track north of Halcrow Lake 5, a long narrow building three blocks east of the railway line 6, and a series of large buildings southeast of that 7. The last is Keewatin Community College[i] which was at the time one of three community colleges in Manitoba, the others being Assiniboine Community College in Brandon and Red River Community College in Winnipeg. In the east a cleared area through forest 8 is followed by a power line leading to transformers 9 in the area where the wood processing plant used to be (#11 on figure 15.9). The railway spur leading to the plant still exists 10, leading to a narrow light-toned building 11. The forestry industry has not deserted The Pas but the processing plant is now located outside the city.
Other changes include a new road bridge 12, west of the railway bridge 13 across the
