The increase in scale results in an even smaller area covered; the photo side is 2.27 miles (3.7 km) with an area of 5.15 square miles (13.34 square km). This results in much more detail being detectable, particularly when compared with figure 1.15a (smallest scale). Details seen along the Assiniboine River 1 are sand bars 2 and the exact location of the mouth of the Cypress River 3. Meander scrolls 4 indicate previous river positions. Tonal variations in the woodland produce a mottled texture 5, and deciduous trees with rounded shadows 6 can easily be distinguished from coniferous trees with triangular shadows 7. Details of a gravel pit 8 east of PTH 34 9 can be obtained whereas the pit is only just identifiable in figure 1.15a. One final detail observable is supports for the bridge across the Assiniboine, five of them in all 10.
