14.11: Haylands Near Oak Lake
Oak Lake and Plum Lakes are glacial lake remnants in the area formerly occupied by glacial Lake Hind. Land southwest of Oak Lake is very flat with a surface close to the water table resulting in marshy areas 1.
A dike runs along the shore of the lake 2 with a narrow waterway behind 3. Although none of this area is actively cropped for cereals, a slight drop in water table has allowed the land to be used for hay. Lines followed by equipment used when cutting and assembling the hay can be seen criss-crossing the area 4. Small black dots 5 are hay piles throwing shadows due north, indicating that the photo was taken near noon.
Section 6 and quarter section lines 7 are visible, but because of the wet surface there are no settlements in the area.
