This larger scale photo covers only a small part of the area shown on figure 1.15a. The side of the photo measures 5 miles (8 km) for an area of 25 square miles (64 square km). However, more detail can be observed than on 1.15a; for example, sand bars 1 can be seen along the course of the Assiniboine River 2. But perhaps the clearest example is the possibility of locating individual trees 3, some of which can be identified as coniferous trees 4 on the basis of their shadow shapes. Note also south of the Assiniboine, east of PTH 34 5 an area of deciduous woodland has tonal variations 6 which produce a mottled texture, whereas the same area at the smaller scale of figure 1.15a has a uniform tone that produces a smooth texture.
