7.17: Correction Line Between Townships 34 and 35 South of Swan River

The photograph shows the wooded—dark-toned—northeast corner of Duck Mountain 1 with the fertile Swan River Plain to the north. The correction line between townships 34 and 35 can be seen by tracing the range line between ranges 27 and 28 WI 2 north until it reaches the township line where it jogs west about 1.25 miles (2 km) 3. The same can be done with the range line between ranges 28 and 29 WI 4 with the same result except that the jog is slightly larger 5.

This area was surveyed using the Third System of the DLS in which there is a north/south road allowance every section, but east/west allowances occur only every two sections. This is reflected in the predominance of north/south light-toned gravel roads 6. One road 7 is an oddity: it runs along a section line where there is no road allowance.

The drainage in this flat area is generally to the north. A series of small creeks—Lobstick Creek 8, Thomas Creek 9, Hay Creek 10, Ruby River 11, and Roaring River 12—with dark-toned wooded sides drain eventually into Swan River 13 that meanders across the northwest corner.

The main linear features include the CN railway line 14 that traverses the area linking the settlements of Durban 15 and Kenville 16. In the former, the railway line determines the road direction, whereas in Kenville roads are oriented with respect to the DLS system. Part of the CN route is also followed by PTH 83 17 but it digresses from it in the north 18 and south 19. Rather unusually, several almost white clouds can be seen 20 casting dark-toned shadows to the north 21, indicating that the photo was taken near noon sun time.
