The distribution of agricultural land in south and central Manitoba is easily mapped using small-scale images that provide an overview. At a larger scale the patterns produced by various stages of harvesting provide some of the most distinctive images of southern Manitoba. Old photos record obsolete techniques, and newer images demonstrate techniques used to cope with high evaporation rates and limited precipitation (field shelterbelts and irrigation). As with natural vegetation, so too with crops, colour infrared photos are useful in detecting crop types and diseases.
14.5: An Agricultural Area Northwest of Dauphin
The commonly held perception of Manitoba as a land with endless fields of grain with little variation is grossly inaccurate as demonstrated by this photo. This relatively flat land is located east of the foot of Duck Mountain (off the photo to the west). There is no topographic hindrance to division of the land into sections 1 and quarter sections 2, both of which are easily identified. Using tonal variations as a basis for identification, it is seen that most quarter sections are divided into several fields, as many as 10 in one case 3. This area is near the highest levels reached by Lake Agassiz, and several indistinct strandlines—some of which influence field shapes 4—can be seen. Soils are on the whole good enough for arable agriculture, but a significant percentage of dark-toned woodland remains 5. Variations in tone within cropped fields 6 indicate different crop types, or different stages of the same crop. Fallow fields have a characteristically mottled texture 7.
The eastward-flowing woodland-fringed Valley River 8, with several small abandoned channels 9, traverses the southern part. The small settlement of Valley River 10 is located near where PR 362 11 crosses the river.
The photo shows the border between townships 26 and 27 12. This is the boundary between the first and second systems of the DLS with a minor jog between the two systems resulting in a bend on PR 362 13.
