16.17: Artificial Drainage of Sloughs North of Minnedosa
Here is another photograph of hummocky ground moraine topography with numerous sloughs 1, many surrounded by rings of emergent vegetation 2. Also some have been drained 3 by constructing a ditch 4 leading into a lower level slough 5.
Also notable on this image is a combine 6 producing wider combined rows 7 compared with narrower swathed rows 8. Traffic 9 on the highway in the south 10, provides an example of the photo interpretation criterion, size, in identifying objects. There are 3 objects11, one larger and two smaller; the larger object is a truck, and the two smaller objects, cars.
