Chapter 3: Geologic Structure and Landforms

3.52: The Eastern Ridge of the Brandon Hills

A sharp-crested ridge exists at the east end of the Brandon hills 1; its sides are very steep, close to the angle of repose of the constituent sands and gravels. These permeable rocks produce a dry environment for plant growth. Consequently the ridge is grass-covered, hence its light tone, but trees exist in wetter, more sheltered draws on the ridge side 2, and they are creeping up the east side 3. The tree cover is a mixture of bur oak (Quercus macrocarpa) and aspen (Populus tremuloides); leaves on the latter are often bright yellow at the date when the photo was taken (October 19) and appear light-toned on the image 4. East of the main ridge are three less definite north/south ridges 5, and east of that the land is flat except for a small outlier of the hills 6. Two small intermittent streams 7 that flow to the Little Souris River (off the photo to the northeast) traverse the flat land.

The flat land is fertile, and most of it is used for crop growth except for some fields that are devoted to animal pasture 8. Harvesting of grain crops is complete, leaving behind distinctive harvesting patterns 9. Very dark-toned fields are those that have been left fallow 10, and even on this very flat land, rain splash and wind erosion have produced light-toned crests on slightly elevated land 11. Six farms 12 exist in this area of 6.25 square miles (16.2 square km). Section lines 13 and quarter section lines 14 are clearly visible; PR 340 15 follows one of the section lines. Railway lines on the other hand do not follow the survey system; the CN line 16, long ago abandoned, connected Brandon and Wawanesa. It takes an unexpected loop in the north 17, possibly to meet the Little Souris River just off the photo, at an appropriate point.
