7.18: Boundary of First and Third Systems of the DLS Near Sifton

The photograph shows an agricultural area near Sifton 1 with dark-toned woodland 2 in the west. The boundary between the First and Third Systems of the DLS was set at the seventh correction line north of township 26 (or the eighth in the case of range 29). Fractional townships and ranges were required at the junction of the two systems; for example, township 27 shown here was only four sections from north to south. The township line between township 26 and 27 runs along the southern edge of the photo 3, and that between townships 27 and 28 4 runs just north of Sifton. There is a minor jog on the range line between ranges 19 and 20 WI at the crossing from township 26 to 27 5. This results from an imperfect contact between the First and Third Systems. A “normal” correction this far west would be almost a mile. Townships 27 and 28 were surveyed according to the Third System with east/west road allowances every two sections, hence the scarcity of light-toned east/west gravel roads, especially in township 28.

The land is flat with a gentle incline to the east towards Dauphin Lake. Several tree-fringed creeks 6 drain in that direction. At least five Lake Agassiz strandlines can be identified 7 on the basis of tonal variations reflecting land use differences.

The CN line 8 runs north/south through Sifton and bifurcates just to the north 9. The road system in Sifton has the unusual distinction of orientation parallel to and right angles to both the railway and the DLS. Finally PR 267 runs east/west through Sifton 10.
