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.
